Wireless Infrared Beam Sensor for Auto Gate
Wireless Infrared Beam Sensor is a high-performance active photocell designed to provide reliable obstacle detection and safety control for automatic gates, sliding doors, and perimeter security systems. With its battery-powered transmitter and IP55 weather-resistant housing, this sensor offers a convenient wire-free solution for both indoor and outdoor installations-2-3.
How It Works
The sensor consists of a transmitter and a receiver. The transmitter emits an invisible 940nm infrared beam toward the receiver. When a vehicle, person, or object passes through and breaks the beam, the sensor instantly sends a relay signal to the gate controller, triggering an action such as stopping, reversing, or preventing the gate from closing-3-7. This ensures safe operation by preventing accidents and vehicle damage.
