No Underground Wiring!

The Optex 18-Foot Range Microwave & Ultrasonic Vehicle Presence Sensor detects the presence of moving or stationary vehicles all while having the ability to ignore human movement. Unlike other vehicle sensor units, it installs above the ground, eliminating the hassles associated with installing a ground loop. You won't have to worry about cutting concrete or having to stop traffic through your driveway during installation.

The Optex 18-Foot Range Microwave & Ultrasonic Vehicle Presence Sensor features adjustable microwave and ultrasonic detection patterns. Microwave detection patterns are adjustable from 6.56 to 18.04 feet, and ultrasonic detection patterns are adjustable from 1.9 to 3.28 feet. It also features 5 selectable menu settings options to ignore human movement.

  • Detects moving or stationary vehicles using microwave and ultrasonic wave technology
  • Ignores human movement with 5 selectable menu setting options
  • Microwave sensor detects the presence of a vehicle based on FMCW (Frequency-Modulated Continuous-Wave)
  • Built-in heater reduces snow on the sensor (automatically activates based on the outside air temperature)
  • Installs above ground and is not affected by underground obstructions
  • No ground loop necessary for installation

Installation Details

The microwave and ultrasonic vehicle presence sensor easily mounts 2 to 3 feet off the ground and wires directly to the gate operator. No additional loop detector, the need for special programmers, or the need to stop traffic through the driveway during installation are required. A simple to use menu with visual indicators provides a simple and quick installation.

Note: Always install the sensor on the vertical pole that is mounted in or on the ground. Installing a sensor on a tilted pole will result in a detection of the ground by the ultrasonic sensor and correct operation is not ensured.
