This heavy duty vehicle detection sensor operates as a Normally Open (N/O), momentary switch, making contact when pressed by a vehicle wheel. When properly installed, it will deliver millions of cycles of trouble-free operation, and is an excellent replacement for expensive "induction loop" vehicle detection sensors.
The RBMA vehicle sensing switch is double-sealed for weather-resistance. It is supplied in a steel mounting channel which has flanges for fastening with studs, nails or cement. This vehicle sensing switch is suitable for asphalt surfaces as well as concrete roadways.
