EMX Ultrasonic Vehicle Detector, model USVD-4X.

Includes Detector, mounting box, & 12 VAC power supply (not pictured).


This drive thru vehicle detector uses Triangular Planar Array (TPA) technology to detect the presence of a vehicle. This ultrasonic vehicle detector handles any drive thru operation, including fast food, banking, pharmacies, car washes and parking.

Utilizing TPA technology, the detection head consists of 4 ultrasonic transducers that connect to the internal microprocessor-based control board. The detection head “scans” the expected location for a vehicle and activates its output upon detection of a vehicle.


  • Triangular Planar Array Technology USVD-4X
  • Aux. relay, settings for pulse on ENTRY, EXIT or BOTH
  • Output delay option for 1, 2 and 4 seconds
  • Operating range: 1ft. – 5ft.
  • Response time: 2.0 seconds
  • Supply Voltage12…24 VDC/VAC
  • Relay output configuration: 2 SPDT (form C)
  • CE compliant



We'll normally steer you towards the magnetic systems (in-ground loop with detector) but there are instances where these are better (poor condition of concrete/asphalt, dirt lane, landlord or site limitations won't allow a loop to be cut in).  The reliability & durability of these since ~2014 has improved to the point that we have very few reservations in recommending these ultrasonic detectors.

Placement becomes more important on curved Drive-Thru lanes.  Feel free to call with any questions that you might have
