Automatic Swing Door Opener Current Safty Sensor with Left-type and Right-type for Shopping Mall

The M-903 Laser Safety Curtain Sensor is a safety protection device specially designed for automatic doors. It is available in left-type and right-type models, with silver and black appearance options. Adopting Time of Flight (TOF) detection principle, it is equipped with 890nm infrared laser (Class I eye-safe laser) and 6 laser beams, providing double protection of anti-pinch and safety sensing for automatic doors.

Powered by AC/DC 12-30V wide voltage, the product has a standby current of 45mA (powered by DC 12V) and an action current of 85mA (powered by DC 12V), with an external dimension of 153(L)x77(W)x30(H)mm and an operating temperature range of -25°C to 55°C, adapting to various environments. In terms of core performance, the detection response time is ≤50ms, the detection angle can be adjusted between 5°-10°, the maximum installation height is up to 5.5m (10% reflectivity), the scanning range is at least 300mm from the ground, supporting 8-level height adjustment (10cm per level), and the on/off of beams 5-6 can be controlled individually. It supports NO/NC signal output, with dual functions of safety presence and anti-collision. After installation, it needs 16-30 seconds of background self-learning. After learning, the blue indicator light stays on and enters the normal working state.

Product description

▪Safe Protection, Rapid Response:6 laser beams provide full coverage detection, with a detection response time of ≤50ms. It immediately outputs STOP/REOPEN signals when encountering obstacles, effectively avoiding the risk of automatic door pinching; Class I eye-safe laser ensures safe use.

▪Flexible Adjustment, Wide Compatibility:The detection angle is adjustable between 5°-10°, the scanning height supports 8-level adjustment (10cm per level), and some beams can be controlled individually, adapting to automatic doors of different heights and widths. It supports normal/stable working modes, and the stable mode can cope with complex scenarios such as falling leaves, complex ground, and rainy days.

▪Easy Installation, Strong Adaptability:Supports two installation methods: drilling fixing and non-drilling installation, with a 2-5cm gap reserved between the sensor and the door side. Equipped with a wire hose, the connecting wire can be fixed into a U-shape to avoid wire pinching when the door body moves, making the installation process simple and efficient.

▪Intelligent Self-Learning, Easy Operation:It automatically performs 16-30 seconds of background self-learning after power-on, no complex debugging required, and the factory default parameters can meet regular use. Equipped with clear LED indicators (blue for standby/learning, red for detection) and beep prompts, the working status is clear at a glance.

▪Wide Voltage Adaptation, Wide Application:12-30V wide voltage power supply, compatible with different automatic door power supply systems; the operating temperature ranges from -25°C to 55°C, with strong resistance to high and low temperatures, suitable for various indoor and outdoor automatic door scenarios such as shopping malls, offices, and residences.

▪Flexible Signals, High Compatibility:Supports NO/NC signal switching, and the safety presence and anti-collision functions can be selected via DIP switch, which can be seamlessly connected with various automatic door controllers. Master-slave design, can be connected to the automatic door machine individually or separately, with flexible wiring.
