Product Description

20kHz - 170kHz Single Channel AC DC Vehicle Loop Detector

High Temperature Stability Single Channel AC DC Voltage Vehicle Loop Detector

About Loop Detectors

Loop detectors are essential for vehicle detection applications including access monitoring, security systems, and traffic management. The output signal controls door and gate mechanisms, operates barriers, manages traffic light systems in parking facilities, and activates card dispensers.

Functions and Features

Reset Switch: Enables manual reset during commissioning and testing, allowing the detector to re-tune the sensing loop
Selectable Pulse Time: Configures pulse relay duration for 1 Second or 0.5 Seconds
Pulse Relay Selection: Configurable to energize on vehicle detection or when vehicle leaves the loop
Sensitivity Boost: Sets undetect level to maximum sensitivity to prevent loss of detection for high-bed vehicles
Switch Selectable Sensitivity: 4 sensitivity settings for flexible configuration
Switch Selectable Frequency: 4 frequency settings to prevent cross-talk between adjacent loops
Filter Option: Provides delay between vehicle detection and output relay switching to prevent false detection
Permanent Presence Option: Ensures continuous vehicle detection during extended parking periods
