Description
Dual Channel Vehicle Loop Detector with Direction Detection
This dual-channel vehicle loop detector is designed for parking systems requiring two road-loop inputs in one controller. CH1 and CH2 can monitor separate detection areas or be installed sequentially to evaluate vehicle crossing order for direction recognition and corresponding relay response.
Dual Channel Vehicle Loop Detector with Two Loop Inputs Direction Detection and Relay Output for Parking Systems
Key Features
  • Two independent inductive loop inputs: CH1 and CH2
  • Vehicle direction recognition based on CH1/CH2 activation sequence
  • Six selectable operating modes for different parking and traffic logic
  • Eight sensitivity levels per channel (0.015% to 0.8%)
  • Four selectable frequency bands (20-100kHz)
  • Presence and pulse relay functions
  • Automatic reset and permanent-presence operation
  • Trailer sensitivity enhancement
  • LED indication for power, detection status, and loop faults
How Direction Detection Works
For directional applications, two sensing loops are placed sequentially in the lane. Vehicle activation sequence (CH1→CH2 or CH2→CH1) determines travel direction. The selected working mode controls relay output generation for parking controller logic.

Installation Guidelines
  • Coil cutting size: rectangle, length 1.0-2.0 meters, width 0.8-1.2 meters
  • Avoid right angles at corners
  • Use ferromagnetic wires for induction coil (total length up to 500 meters)
  • Keep product plug and socket in vertical direction during installation
