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.

03 · Machine Safeguarding

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.

01
Machine Guarding

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.

Typical Considerations Hazard access · detection capability · stopping performance · safeguard positioning
02
Access Guarding

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.

Typical Considerations Opening size · approach direction · access frequency · restart behavior
03
Perimeter Guarding

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.

Typical Considerations Perimeter access · entry detection · restart control · cell layout
04
Area Protection

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.

Typical Considerations Protected area geometry · approach speed · field layout · machine stopping behavior
05
Mobile Equipment

Mobile Robot Protective Scanning

Mobile equipment introduces moving hazardous zones that may change with travel speed, direction, stopping distance and the surrounding operating environment.

Typical Considerations Protective field · warning field · stopping distance · vehicle movement
06
Material Access

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.

Typical Considerations Opening geometry · material flow · personnel access · restart / muting strategy
Safeguarding Logic

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.

Step 01 Identify how the hazard can be reached Hand access, body access, opening, perimeter, floor area, mobile approach or material-transfer opening.
Step 02 Determine the required protective function Presence detection, access detection, area protection, mobile protective scanning or controlled material access.
Step 03 Select and validate the safeguarding technology Device selection, safeguard positioning, stopping time, control architecture and final validation follow from the actual risk.
The safeguarding method should match the actual access path to the hazard. A point-of-operation opening, robot-cell perimeter, floor area, mobile travel zone and material-transfer opening can require different protective technologies and control strategies. Final selection should follow the machine risk assessment and complete safety-function requirements.

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.

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.

Define each sensing requirement independently: personnel protection, obstacle detection and navigation are different functions with different device and system requirements.

09 · Frequently Asked Questions

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.
