Anti-Crush Photoelectric Sensor for Sliding Door Barrier Gate Safety - Fast Response, Low Power Consumption 12-24 V

The Anti-Crush Photoelectric Sensor is a critical safety solution designed to prevent accidents and equipment damage in sliding doors, barrier gates, and automated access systems. Utilizing advanced infrared beam technology, this sensor detects obstacles, pedestrians, or vehicles in the door’s path with a rapid response time of ≤0.1 seconds, ensuring immediate interruption of door movement to avoid crushing incidents. Engineered for versatility, it supports 12-24V AC/DC dual power input, making it compatible with a wide range of industrial and commercial systems without requiring additional voltage converters. Ideal for high-traffic environments like shopping malls, hospitals, and warehouses, the sensor operates flawlessly in temperatures from -10°C to +60°C and features an IP65 waterproof and dustproof rating for reliable outdoor performance. Its rugged ABS+PC UV-resistant housing withstands harsh weather, direct sunlight, and corrosive elements, ensuring long-term durability even in extreme conditions. Certified by CE and FCC, this sensor meets global safety and electromagnetic standards, providing peace of mind for facility managers and system integrators.

This photoelectric sensor excels in anti-interference performance, using precision-focused infrared beams to eliminate false triggers caused by ambient light, fog, or dust. The 500mA@48V relay output enables seamless integration with door controllers, alarms, or emergency stop mechanisms, delivering instant signal transmission to halt door movement when an obstruction is detected. Designed for flexible installation, the sensor maintains consistent detection accuracy even at low mounting heights (20-40cm), perfect for low-profile sliding doors or barrier gates. Its low-power design (≤35mA operating current) reduces energy costs and supports solar-powered or battery-operated setups, ideal for remote or eco-friendly installations. Maintenance is simplified thanks to modular transmitter (TX) and receiver (RX) units, which allow quick alignment adjustments without system downtime. Applications extend beyond sliding doors—deploy it in industrial overhead doors, security checkpoints, or automated toll booths where safety and reliability are paramount. Installers praise its plug-and-play setup and intuitive LED status indicators, which streamline troubleshooting and ensure optimal performance. Whether safeguarding public spaces or industrial facilities, this sensor is the trusted choice for enhancing safety, reducing liability risks, and ensuring compliance with modern automation standards.
