Lusdetector Nice LP21 enkelkanaals lusdetector (model 28130)

The Nice LP21 single-channel loop detector (model 28130) is an inductive vehicle detector designed to sense metal objects passing over a buried or surface-mounted loop wire. It provides reliable single-channel detection suitable for integration with gates, barriers and access control systems. The device monitors loop continuity and vehicle presence, and outputs a switching signal to trigger control panels, relays or safety devices in automated entry and traffic management installations.

Advantages

The loop detector offers stable vehicle detection with adjustable sensitivity to accommodate different loop sizes and vehicle types. Its single-channel design simplifies installation and system integration while maintaining low power consumption and consistent operation in typical parking or gate automation environments. Built-in features support immunity to external noise and false triggers, making it suitable for varied site conditions.

Suitable for

• Automatic swing and sliding gates for vehicle detection
• Parking barriers and access lanes to control entry/exit
• Traffic sensing at private or commercial entrances
• Integration with access control systems and relay interfaces

Key specifications

• Detection type: single-channel inductive loop detector for metal objects
• Loop input: single loop wire connection, suitable for buried or surface loops
• Adjustable sensitivity to detect a wide range of vehicle sizes
• Output: switching control output compatible with gate and barrier control panels
• Power consumption: low-power design suitable for continuous operation
• Installation: DIN-rail or panel mounting options depending on system requirements
• Operating conditions: designed for indoor or protected outdoor control enclosures

How to use

Install the loop wire according to site geometry and the gate or barrier manufacturer’s recommendations. Mount the loop detector in a control cabinet or on DIN-rail near the access control panel and connect the loop input, power supply and the control output to the relevant terminals. Adjust sensitivity and presence timing settings to match vehicle profiles and reduce false detections. Test detection performance across typical vehicle types and refine settings where necessary to ensure reliable operation.

Recommendations

Place the detector inside a weather-protected enclosure and follow grounding and loop installation best practices to minimize interference. Regularly inspect loop continuity and retune sensitivity after major site changes such as pavement repairs or long-term shifts in traffic patterns.
