Optex Technologies Inc. manufactures automatic door sensor products. Optex
makes a wide variety of sliding door sensors, swinging door sensors, and
folding door sensors that are commonly seen on most automatic door manufacturer's
door systems. Door sensors are designed to detect moving or stationary
people in the path of the door.
A sensor detects traffic as it is approaching and sensors for automatic
doors can be pressure sensors where a floor mat activates the door if
someone is standing on it, infrared curtains or beams that shine invisible
light onto sensors so that if something blocks the beam the door will
open, remote sensors where a door is activated by a portable remote control
or garage door control (infrared or radio waves), and motion sensors that
use low power microwave radar.
