Product Overview

The Detex 104790 Safety Presence Sensor is an active infrared presence sensor designed for use with automatic door systems to detect pedestrians, carts, and other obstacles within the door threshold area. Utilizing Floor Reflection Method (FRM) technology, the sensor creates a precise optical safety field that helps prevent automatic doors from closing when an object is present in the detection zone. The sensor provides up to 32 individual detection zones through four rows of presence detection, allowing comprehensive coverage of the doorway area.

We supplies commercial door hardware, access control products, and OEM replacement components for professional security and facility applications.
