Industrial Safety Solutions for Machine Guarding & Automation
Select sensing and safeguarding technologies around the machine, protected zone and automation task — from point-of-operation guarding and robot-cell access to mobile-robot safety, obstacle detection and navigation.
Industrial Safety Solutions by Application
Start with the machine, automation cell or material-flow process. Different applications create different access points, hazardous zones and sensing tasks, so the safeguarding technology should be selected around the actual application.
Machine Guarding & Point-of-Operation Safety
Safeguarding solutions for operator access, hazardous machine openings and working zones where human interaction occurs during production, loading, unloading or setup.
Robot Cell & Automated Workcell Safety
Safeguarding around robot cells and automated work areas where access, perimeter protection and hazardous movement must be considered together.
AGV / AMR Safety, Detection & Navigation
Mobile robots may require different sensing functions for safety-rated protective scanning, general obstacle detection and navigation. These functions should be defined separately.
Material Handling & Transfer Safety
Safeguarding for automated material movement where people, pallets, conveyors, lifts or transferred loads interact with machine openings and hazardous zones.
Application principle: the machine or workflow describes the context, but it does not by itself determine the protective device. Hazard access, safety performance, sensing geometry, stopping behavior and the required machine response should be defined before final product selection.
Machine Safeguarding by Hazard & Access Type
Machine guarding should start with how a person can approach, reach or enter the hazardous area. Point-of-operation access, machine openings, cell perimeters, floor areas, mobile travel zones and material-transfer openings create different safeguarding requirements.
Point-of-Operation Guarding
Protect the area where the machine performs hazardous work and where an operator may place a hand, arm or other body part during loading, unloading, positioning or production.
Openings & Operator Access
Safeguard loading openings, access points and other defined machine openings where personnel can approach a hazardous area during normal operation, setup or intervention.
Perimeter & Cell Access
Protect robot cells, automated workcells and fenced machinery where personnel enter through defined access points or approach the boundary of a larger hazardous area.
Floor Area & Hazardous Zone Monitoring
Monitor a defined two-dimensional area around machinery, robot cells or automated equipment when protection cannot be represented by a single straight access line.
Mobile Robot Protective Scanning
Mobile equipment introduces moving hazardous zones that may change with travel speed, direction, stopping distance and the surrounding operating environment.
Material Transfer Openings
Safeguard openings used for pallets, products, containers or carriers where the intended material flow passes through a machine or cell boundary and unintended personnel access must be considered separately.
Define the Hazard Before Choosing the Device
Machine safeguarding is not a single product category. The appropriate protective technology depends on the hazardous motion, access route, protection geometry, machine stopping behavior and required safety function.
Choose the Right Safety Sensing Technology
Safety light curtains, safety laser scanners, industrial 2D LiDAR and safety relay modules solve different engineering problems. Start with the required protective or sensing function, then move to the product family that fits the application.
Safety Light Curtains
Suitable for defined openings and access lines where a person entering the protected path must be detected before reaching the hazardous machine area.
Safety Laser Scanners
Suitable for safety-related area monitoring where the required protective zone is two-dimensional or flexible field geometry is needed around machinery, robot cells or mobile equipment.
Industrial 2D LiDAR
Designed for industrial detection, measurement and mobile-robot perception tasks. Selected raw-data configurations can provide scan data for applications such as AGV / AMR navigation.
Safety Relay Modules
Used to monitor compatible safety-device signals, including ENT safety light curtains and SH safety laser scanners where the electrical and safety architecture is appropriate, and to provide relay interfaces for downstream machine safety control.
The documented SRB-2A1B configuration supports dual-channel monitoring, reset selection and muting / shielding logic through its dedicated muting inputs. Muting is implemented as part of the complete safeguarding architecture; it is not a built-in function of the ENT safety light curtain.
Safety and industrial sensing are different functions. Standard industrial 2D LiDAR should not be presented as a substitute for a required safety-rated protective device. Likewise, the safety performance of a machine function depends on the complete sensing, control, final-control and validation architecture rather than the rating of one component alone.
Machine Safety Solutions for Presses, Packaging & Machine Tools
Machines with frequent loading, unloading, setup or operator intervention require safeguarding around the actual access path to the hazard. The same machine may need different protection at the point of operation, material opening or surrounding area.
Press Machine Safety
Press operations often combine a hazardous point of operation with frequent manual loading, positioning or part removal. Safeguarding must consider how quickly a person can reach the hazard and how the machine stops after the protective device is triggered.
Packaging Machine Safety
Packaging systems may combine conveyors, product transfer, loading openings and operator intervention points. Safeguarding should protect personnel while also accounting for intended material flow through the machine.
Press Brake Safety
Press brakes create a hazardous working zone around the tooling and bending process. The safeguarding concept must consider operator access, workpiece handling, machine stopping behavior and the practical working space required around the bend.
Machine Tool Safety
Machine tools can require access protection around loading areas, doors, automated handling interfaces or open machine zones. The safeguarding method depends on whether access is occasional, frequent or integrated into the production cycle.
Safety Distance Is a System Calculation
For electro-sensitive safeguarding, device response time is only one part of the required separation distance. Machine stopping time, safety-control response, detection capability, approach conditions and applicable reaching factors must be considered together.
Sensor Response Time
Use the response time of the exact selected safety device and configuration.
Actual Stopping Time
Include the machine stopping behavior relevant to the safeguarded hazardous movement.
Safeguard Separation Distance
Determine the required safeguard position from the applicable method and complete machine risk assessment.
Robotics, Material Flow & Mobile Automation
Automated systems can combine personnel safeguarding with detection, material-flow and navigation functions. Define these tasks separately before selecting the sensing or safety technology for the application.
Robot Cell & Robotic Workcell Safety
Robot cells and automated workcells can require perimeter protection, controlled access and area monitoring around hazardous robot or machine movement.
Material Flow & Transfer Safety
Automated material movement creates transfer points and openings where pallets, products or carriers may pass while personnel access still needs to be considered.
AGV / AMR Safety & Mobile Sensing
Mobile robots can require separate systems for safety-related personnel protection, general obstacle detection and navigation or environmental perception.
Separate the Sensor Task Before You Choose the Technology
A robot cell, conveyor system or AGV can contain several different sensing requirements. Define the personnel-access, safety and automation functions independently before selecting the device.
Safety Laser Scanner vs Industrial 2D LiDAR
Both technologies scan a two-dimensional environment, but they serve different engineering functions. A safety laser scanner is selected for safety-related protective monitoring, while industrial 2D LiDAR is selected for detection, measurement, perception or navigation-related sensing.
Safety Laser Scanner
Use when the application requires a safety-related protective field as part of the machine or mobile-equipment safeguarding function.
Industrial 2D LiDAR
Use when the task is general industrial detection, environmental measurement, perception or selected raw-scan-data navigation rather than a personnel-protection safety function.
One Vehicle Can Need Both Technologies
A mobile robot may use one sensing system for the safety function and another for perception or navigation. The presence of LiDAR on an AGV does not automatically mean that the LiDAR performs personnel protection.
Machine Safety Standards & Engineering Resources
Machine safeguarding decisions sit inside a wider engineering framework: risk assessment, safety-related control design, protective-device selection, safeguard positioning and final validation. Use these standards as topic routes, then open the detailed guides and calculation tools for the specific task.
Start with the Hazard
Identify hazardous situations, foreseeable access and required risk reduction before selecting the protective technology.
Define the Required Safety Performance
Safety-related control functions should be evaluated as complete systems rather than inferred from the rating of one individual component.
Device Requirements & Positioning
Electro-sensitive protective equipment and safeguard positioning require consideration of device capability, response time, machine stopping time and human approach.
OSHA & Consensus Standards
U.S. projects require evaluation of applicable OSHA machine guarding requirements together with relevant machine-specific and consensus safety standards.

ISO 13855:2024 Safety Distance Calculator
Use the CCH calculator for preliminary safety light curtain separation-distance calculations using system stopping time and applicable reaching factors. Final installation still requires the machine’s actual stopping performance and complete safety validation.
Industrial Safety Solutions FAQ
Common questions about machine safeguarding, safety sensor selection and the difference between safety-related protection and general industrial sensing.
01 What are industrial safety solutions?
Industrial safety solutions combine safeguarding devices, safety-related control functions, machine design measures and validation to reduce risk around hazardous industrial equipment.
The appropriate solution depends on the machine, hazard, personnel access route, stopping behavior and required safety function. A safety sensor should therefore be selected as part of the complete machine safeguarding concept rather than as an isolated component.
02 How do I choose the right machine safeguarding method?
Start by identifying the hazard and determining how a person can reach or enter the hazardous area. Then define what the protective device must detect and what safe machine response must follow.
Typical factors include point-of-operation access, opening or perimeter geometry, approach direction, required detection capability, machine stopping time, restart behavior and the required safety performance of the complete control system.
03 Should I use a safety light curtain or a safety laser scanner?
A safety light curtain is generally well suited to a defined opening or access line between an emitter and receiver.
A safety laser scanner is generally more suitable when the required protective zone is two-dimensional or when flexible field geometry is needed around machinery, robot cells or mobile equipment.
Final selection still depends on the risk assessment, required safety function, stopping behavior and application geometry.
04 What is the difference between a safety laser scanner and industrial 2D LiDAR?
A safety laser scanner is selected for a safety-related protective function, such as personnel protection or protective area monitoring.
Standard industrial 2D LiDAR is used for general sensing tasks such as detection, measurement, environmental perception or configuration-dependent scan-data applications.
Similar scanning principles do not make the two device categories interchangeable. A standard industrial LiDAR should not be substituted for a required safety-rated protective device.
05 What safety sensor is suitable for a press machine?
Press machine safeguarding frequently requires protection around the point of operation where an operator loads, positions or removes workpieces. Safety light curtains are one commonly used technology for defined access paths, but suitability cannot be determined from the machine type alone.
The application must also consider machine stopping time, approach direction, required detection capability and the resulting safeguard position. See the Press Machine Safety application guide for the dedicated application discussion.
06 Can an AGV or AMR use both a safety laser scanner and 2D LiDAR?
Yes. The same mobile robot can require separate sensing technologies for different functions.
A safety laser scanner can form part of the safety-related protective function, while industrial 2D LiDAR can be used for obstacle detection, environmental perception or, in selected configurations, raw scan data for navigation.
These functions should be defined and evaluated separately. See the AGV Safety application guide for the application-level discussion.
