In packaging, palletizing and material-handling lines, boxes and pallets are forced through protected openings on the line dozens of times each hour.\n      <\/p>\n      \n      <div class=\"module-text-block module-highlight-box\">\n        At its core, this safety function is an automatic, temporary suspension of the light curtain&#8217;s protection \u2014 triggered by dedicated muting sensors that distinguish material from personnel. When a series of two or more muting sensors (which are programmed to recognize specific material size and sequence patterns) sense an object, the safety function is disabled for the brief time period required to let the material pass through the aperture. As soon as this object exits the sensing range, complete safety protection is reinstated, to include the full &#8220;auto-timed&#8221; function, and not once is it ever necessary to deactivate.\n      <\/div>\n      \n      <p class=\"module-text-block\">\n        A key distinction separates these two functions: blanking permanently masks specific beams for fixed obstructions in the field, while muting temporarily suspends the full protective function based on real-time sensor data. Both serve production efficiency \u2014 blanking handles static interference, muting handles dynamic material flow.\n      <\/p>\n    <\/div>\n\n  <\/div>\n<\/section>\n<\/div><\/div><\/div>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-stackable-columns alignfull stk-block-columns stk-block stk-426d4ce\" data-block-id=\"426d4ce\"><style>.stk-426d4ce {margin-bottom:0px !important;}<\/style><div class=\"stk-row stk-inner-blocks stk-block-content stk-content-align stk-426d4ce-column alignfull\">\n<div class=\"wp-block-stackable-column stk-block-column stk-column stk-block stk-c7f210a\" data-v=\"4\" data-block-id=\"c7f210a\"><div class=\"stk-column-wrapper stk-block-column__content stk-container stk-c7f210a-container stk--no-background stk--no-padding\"><div class=\"stk-block-content stk-inner-blocks stk-c7f210a-inner-blocks\">\n<section id=\"qjkh-muting-safety-module\">\n    <style>\n        \/* ==========================================================================\n           1.

Every unit ships with optical synchronization, IP65 ingress protection, and infrared one-button PNP\/NPN configuration \u2014 eliminating the mode-mismatch errors that account for a significant share of field commissioning callbacks.<\/p>\n        <\/header>\n\n        <div>\n            <h3 class=\"qjkh-title-sub\">ENT Light Curtain Specifications<\/h3>\n            <div class=\"qjkh-specs-grid\">\n                <div class=\"qjkh-spec-card\">\n                    <div class=\"qjkh-spec-val\">10 \/ 20 \/ 40 mm<\/div>\n                    <div class=\"qjkh-spec-label\">Optical Axis Spacing<\/div>\n                <\/div>\n                <div class=\"qjkh-spec-card\">\n                    <div class=\"qjkh-spec-val\">14 \/ 25 \/ 45 mm<\/div>\n                    <div class=\"qjkh-spec-label\">Detection Accuracy<\/div>\n                <\/div>\n                <div class=\"qjkh-spec-card\">\n                    <div class=\"qjkh-spec-val\">0\u201370 m (Model E)<\/div>\n                    <div class=\"qjkh-spec-label\">Max Detection Distance<\/div>\n                <\/div>\n                <div class=\"qjkh-spec-card\">\n                    <div class=\"qjkh-spec-val\">6.0\u201330.8 ms<\/div>\n                    <div class=\"qjkh-spec-label\">Response Time<\/div>\n                <\/div>\n                <div class=\"qjkh-spec-card\">\n                    <div class=\"qjkh-spec-val\">24 V DC \u00b120%<\/div>\n                    <div class=\"qjkh-spec-label\">Operating Voltage<\/div>\n                <\/div>\n                <div class=\"qjkh-spec-card\">\n                    <div class=\"qjkh-spec-val\">IP65<\/div>\n                    <div class=\"qjkh-spec-label\">Protection Class<\/div>\n                <\/div>\n            <\/div>\n        <\/div>\n\n        <div>\n            <h3 class=\"qjkh-title-sub\">Detection Distance Selection<\/h3>\n            <div class=\"qjkh-table-wrapper\">\n                <div class=\"qjkh-table-header\">\n                    <div>Model Code<\/div>\n                    <div>Detection Range<\/div>\n                    <div>Typical Application<\/div>\n                <\/div>\n                <div class=\"qjkh-table-row\">\n                    <div style=\"font-weight: 700 !important; color: #181818 !important;\">A<\/div>\n                    <div>0\u201310 m<\/div>\n                    <div>Small press guards, compact workcells<\/div>\n                <\/div>\n                <div class=\"qjkh-table-row\">\n                    <div style=\"font-weight: 700 !important; color: #181818 !important;\">B<\/div>\n                    <div>0\u201316 m<\/div>\n                    <div>Standard conveyor entry\/exit points<\/div>\n                <\/div>\n                <div class=\"qjkh-table-row\">\n                    <div style=\"font-weight: 700 !important; color: #181818 !important;\">C<\/div>\n                    <div>0\u20135 m<\/div>\n                    <div>High-speed short-range applications<\/div>\n                <\/div>\n                <div class=\"qjkh-table-row\">\n                    <div style=\"font-weight: 700 !important; color: #181818 !important;\">D<\/div>\n                    <div>0\u201340 m<\/div>\n                    <div>Large palletizing systems, wide openings<\/div>\n                <\/div>\n                <div class=\"qjkh-table-row\">\n                    <div style=\"font-weight: 700 !important; color: #181818 !important;\">E<\/div>\n                    <div>0\u201370 m<\/div>\n                    <div>Warehouse perimeter, extended conveyor runs<\/div>\n                <\/div>\n            <\/div>\n        <\/div>\n\n        <div class=\"qjkh-split-grid\">\n            <article class=\"qjkh-card\">\n                <h3 class=\"qjkh-title-sub-lined\">SRB-2A1B Safety Relay Module \u2014 Muting Interface<\/h3>\n                <p class=\"qjkh-text-body\">Our SRB-2A1B safety relay module connects directly to ENT light curtains through dedicated MUT_H and MUT_L signal inputs. It features safety outputs with 2N\/O contacts and 1N\/C contact, supports PNP &#038; NPN signal modes by DIP switches while 4 LEDs are used for showing the status such as CH1 (green) for channel 1, CH2 (green) for channel 2, ERROR (red) for errors, and POWER (red) for power supply indication. The whole circuitry supports self testing to lock the output enabling when the two input signals are not matched with one another to prevent the permanent sounds of muting.<\/p>\n            <\/article>\n            \n            <article class=\"qjkh-card\">\n                <h3 class=\"qjkh-title-sub-lined\">How to Select Your Configuration<\/h3>\n                <p class=\"qjkh-text-body\">Match your application in three steps: first, determine detection distance by the physical length of your guard opening. Second, determine the spacing of the optical axis (10 mm for finger detection, 20 mm for hand detection, 40 mm for body detection in accordance with IEC 61496-1). Third, click the box to select the SRB-2A1B relay and muting sensor kit that is right for your conveyor design &#8211; T-configuration for bi-directional flow or L-configuration for exit-only systems.<\/p>\n            <\/article>\n        <\/div>\n\n        <footer>\n            <p class=\"qjkh-footer-info\">\n                QJKH products are made in our 5,000 sqm electronics workshop fitted with high-end SMT placement lines and MV-6eOMNI 3D AOI inspection, the production requirements are the same as for Cat.4 \/ SIL 3 (Top class) certification under IEC 61496-1:2020 and ISO 13849-1:2023\n            <\/p>\n        <\/footer>\n\n    <\/div>\n\n    <script>\n        document.addEventListener(\"DOMContentLoaded\", function() {\n            var tableRows = document.querySelectorAll('#qjkh-muting-safety-module .qjkh-table-row');\n            \n            tableRows.forEach(function(row) {\n                row.addEventListener('click', function() {\n                    var isSelected = this.getAttribute('data-selected') === 'true';\n                    \n                    \/\/ Clear all highlights\n                    tableRows.forEach(function(r) {\n                        r.style.backgroundColor = 'transparent';\n                        r.setAttribute('data-selected', 'false');\n                    });\n                    \n                    \/\/ Toggle current row highlight\n                    if (!isSelected) {\n                        this.style.backgroundColor = 'rgba(48, 48, 48, 0.04)';

The sensors are designed to see material moving toward the light curtain, starting the muting cycle on a specific sequence- either a certain part of this sequence is what defines a real pallet rather than a person taking a chance at getting into a dangerous area.\n        <\/p>\n\n        <h3 class=\"seo-sub-title\">Muting Sensor Configuration Quick-Reference<\/h3>\n        \n        <div class=\"table-scroll-wrapper\">\n            <table class=\"b2b-data-table\">\n                <thead>\n                    <tr>\n                        <th>Configuration<\/th>\n                        <th>Sensors<\/th>\n                        <th>Direction<\/th>\n                        <th>Key Dimensions (IEC 62046)<\/th>\n                        <th>Best For<\/th>\n                    <\/tr>\n                <\/thead>\n                <tbody>\n                    <tr>\n                        <td>T-Configuration (Crossed)<\/td>\n                        <td>2<\/td>\n                        <td>Bidirectional<\/td>\n                        <td>d1 &lt; 200 mm, d2 &gt; 250 mm; crosspoint inside danger zone<\/td>\n                        <td>Conveyor with two-way pallet flow<\/td>\n                    <\/tr>\n                    <tr>\n                        <td>L-Configuration (Parallel)<\/td>\n                        <td>2<\/td>\n                        <td>Exit only<\/td>\n                        <td>d5 &lt; 200 mm between AOPD and nearest sensor<\/td>\n                        <td>Exit-only conveyor openings<\/td>\n                    <\/tr>\n                    <tr>\n                        <td>4-Beam Parallel<\/td>\n                        <td>4<\/td>\n                        <td>Bidirectional<\/td>\n                        <td>d1, d3 &lt; 200 mm; d2 &gt; 250 mm; sequential timing<\/td>\n                        <td>High-precision palletizing, large irregular loads<\/td>\n                    <\/tr>\n                <\/tbody>\n            <\/table>\n        <\/div>\n\n        <p class=\"b2b-paragraph\">\n            In all cases IEC 62046:2018 specifies a 500 mm diameter matt finished test cylinder must not cause muting to occur &#8211; preventing a human from causing the system to mute as a substitute for material. The maximum time to mute is 4 seconds from the time the first muting sensor is un blocked, a fail-safe timer in the safety controller checks this cycle time and faults if this maximum is exceeded.\n        <\/p>\n        \n        <p class=\"b2b-paragraph\">\n            Proper positioning of the muting sensors relative to the light curtain beam matters more than any other installation variable: the lowest beam of the muting sensor must be at or above the light curtain&#8217;s lowermost beam to prevent muting by a foot. The 200mm d1 and d5 dimensions stems from the 95 th percentile human foot length of 285 mm as specified by ISO 15534-3.\n        <\/p>\n\n        <div class=\"b2b-engineering-quote\">\n            <div class=\"b2b-quote-text\">\n                &#8220;We engineer every ENT muting installation with d5 held under 150 mm (vs IEC 62046 maximum 200 mm) because field data from conveyor retrofits has proven that tighter spacing catches trailing-edge detection failures early, preventing nuisance faults.&#8221;\n            <\/div>\n            <div class=\"b2b-quote-author\">\u2014 QJKH Application Engineering Team<\/div>\n        <\/div>\n\n        <div class=\"b2b-action-wrap\">\n            <a href=\"#ct-popup-788\" class=\"b2b-primary-btn\" id=\"seo-muting-quote-btn\">Get Instant Quote<\/a>\n        <\/div>\n\n    <\/div>\n<\/section>\n\n<script>\ndocument.addEventListener('DOMContentLoaded', function() {\n    var quoteBtn = document.getElementById('seo-muting-quote-btn');\n    \n    if (quoteBtn) {\n        quoteBtn.addEventListener('click', function(e) {\n            \/\/ \u786e\u4fdd\u5f39\u7a97\u76ee\u6807\u5b58\u5728\uff0c\u517c\u5bb9 Blocksy \u7684 #hash \u89e6\u53d1\u673a\u5236\n            var popupTarget = document.querySelector('#ct-popup-788');\n            if (popupTarget) {\n                console.log('Quote Popup Triggered via B2B Module.');\n            }\n        });\n    }\n});\n<\/script>\n<\/div><\/div><\/div>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-stackable-columns alignfull stk-block-columns stk-block stk-6d4a7c9\" data-block-id=\"6d4a7c9\"><style>.stk-6d4a7c9 {margin-bottom:0px !important;}<\/style><div class=\"stk-row stk-inner-blocks stk-block-content stk-content-align stk-6d4a7c9-column alignfull\">\n<div class=\"wp-block-stackable-column stk-block-column stk-column stk-block stk-9a220f1\" data-v=\"4\" data-block-id=\"9a220f1\"><div class=\"stk-column-wrapper stk-block-column__content stk-container stk-9a220f1-container stk--no-background stk--no-padding\"><div class=\"stk-block-content stk-inner-blocks stk-9a220f1-inner-blocks\">\n<section id=\"muting-troubleshooting-module\" aria-labelledby=\"muting-module-heading\">\n    \n    <style>\n        \/* Principle 3: Aesthetics & Fonts \n         * Importing Inter font.
