Commercial-Grade Automatic Door Sensor M-506E: Dual Microwave & Infrared Detection, Auto Open on Human Arrival + Safety Protection

The M-506E Microwave Motion & Infrared Safety Sensor is a dual-function intelligent device integrating microwave motion induction and infrared safety detection. EMC tested, it is specially designed for automatic door scenarios, with dual functions of motion-triggered door opening and safety anti-pinch, adapting to the intelligent control needs of various automatic doors.

Powered by AC/DC 12-30V (±10%) wide voltage, the product has a static current of 75mA (powered by DC 12V) and an action current of 120mA (powered by DC 12V), with a cable length of 2.5m, a maximum installation height of 3500mm, and an external dimension of 268(L)×61(W)×38(H)mm (excluding the bottom shell). It operates within a temperature range of -25°C to 55°C, with strong environmental adaptability. In terms of core performance, the microwave induction adopts 24.125GHz technology, with a detection range of 4m(W)×2m(D); the infrared safety detection uses 940nm modulated light, including 2 safety detection channels and 24 light spots, with a detection range of 2500(W)×600(D)mm (when installed at 2.5m height) and a response time of ≤150ms. It supports optional NO/NC signals, with four background update time modes: 15s, 1min, 30min, and no update. The microwave sensitivity is adjustable in four levels: high, medium, low, and ultra-low. After power-on, it requires 8 seconds of dynamic stability self-learning, and then the green light stays on to enter the standby state.

Product description

▪Integration of Dual Technologies, Safe and Efficient:Microwave induction is responsible for quickly capturing human motion and triggering door opening, while infrared detection real-time monitors the anti-pinch area and immediately outputs safety signals when encountering obstacles, realizing full-process coverage of "trigger-protection" and double guarantee of passage safety.

▪Precise Detection, Strong Anti-Interference:Microwave + infrared composite detection, microwave sensitivity adjustable in four levels, infrared detection depth and width can be manually adjusted to adapt to different door sizes. Supports four background update modes, intelligently identifying fixed obstacles and avoiding false triggers caused by environmental interference.

▪Flexible Adaptation, Wide Application:12-30V wide voltage power supply, maximum installation height of 3.5m, operating temperature range of -25°C to 55°C, can be installed on the lintel of various automatic doors. Supports dual-sensor installation in adjacent areas with separate channels (A/B) to avoid mutual interference, adapting to shopping malls, offices, residences and other scenarios.

▪Easy Installation, Simple Adjustment:Reasonable design of installation holes and wiring holes, supporting surface-mounted wiring. The ABS shell with PMMA optical surface is durable. Detection parameters can be adjusted with special tools, no complex configuration required, and factory default parameters can meet regular use.

▪Clear Status, Convenient Debugging:Distinct indicators: green light (learning/standby), yellow light (microwave motion), red light (infrared safety), with clear working status at a glance. Automatically completes 8-second self-learning after power-on, simple wiring and convenient later maintenance.

▪High Compatibility, Reliable Performance:Supports NO/NC signal switching, which can be seamlessly connected with various automatic door controllers. The microwave transmission power meets safety standards, the core components have stable quality, rapid response and stable output signals, with a long service life.
