Laser Safety Curtain Sensor for Auto Door - Anti-Pinch Human Body Infrared Detector

This laser safety curtain sensor is an intelligent anti-pinch safety accessory specially designed for various doors, adopting TOF (Time-of-Flight) detection technology and equipped with 890nm Class I eye-safe infrared laser, which can accurately detect moving or stationary objects to achieve anti-pinch and anti-collision protection for doors. The product supports 0-25° adjustable detection angle and 7-level adjustable scanning range from the ground, comes standard with normal/stable dual working modes to resist interference from complex environments such as floating dust and rainy days, and is compatible with AC/DC12~30V wide voltage power supply. It has multiple optional sizes and supports parallel connection of multiple units, with a durable aluminum alloy+ABS+PC shell and simple installation and debugging. Assisted by positioning red dots for calibration, it is widely applicable to various doors such as automatic doors and industrial doors, providing all-round safety protection for door operation.
