EMX MRD-1P Radar Presence Sensor

The MRD-1P radar presence sensor is used to indicate the presence of a vehicle or person near a barrier arm. It detects objects over a range of 1–30 ft, with the maximum detection distance adjustable via pushbuttons. The sensor is extremely accurate, measuring distance to within 0.04". Its microwave detection is unaffected by weather conditions such as rain, snow, fog, or sunlight. It features Form C relay outputs for presence detection and pulse-on-entry/pulse-on-exit signaling, along with a 3-digit display for quick configuration.
