DIP Switch Anti Jamming Vehicle Loop Detector 20KHz for Parking Lot Access Control

• Parking lot entrance vehicle detection
• Parking lot space information acquisition systems
• Electronic police traffic light snapshot systems
• Traffic monitoring systems

• Industrial engineering design concept
• Standard industrial guide installation
• Strong anti-jamming capability and stability
• Multiple output interfaces for different scenarios
• Various shape options to meet different requirements
• High temperature stability
• Automatic environmental drift compensation
• Coil automatic fault detection
• Self-detection when DIP switch changes position or output time
• ABS alignment for compact pillar integration
• Adjustable presence output time
• Work mode configurable via DIP switch
• Pulse or permanent output adjustable

Upon power-on, the detector enters self-calibration mode with green LED flashing and red LED off for approximately 1 second. No vehicles should be present on loops during calibration. After calibration, green LED stops flashing and red LED remains off. Red LED illuminates when a vehicle passes over the loop.

DIP1 and DIP2 set sensitivity; DIP3 sets relay 1 presence output time; DIP4 configures relay 2 as presence/pulse output; DIP5 sets presence signal output time; DIP6 sets frequency. Jumper wire connected to open end links PIN16 to NO of relay 1; connected to close end links PIN16 to NC of relay 1.

User-configurable loop work frequency to prevent cross-talk from adjacent loops or environmental frequency interference. Two frequency styles available via DIP6.

Sensitivity adjustable via DIP1 and DIP2 on front panel. Increase sensitivity if vehicle detection fails during testing.

Packaging: Standard export carton/wooden package, with customized packaging available upon request.
