Nice LP21 magnetic induction loop detector, 1-channel, 24 V

Nice LP21 detects a vehicle above an induction loop laid in the road surface. When a car, motorcycle or lorry passes, it sends a signal to the control unit. Use it for automatically opening or closing a barrier or gate, or for car park management.

Features

• Outputs – presence relay and pulse relay, volt-free contacts max. 250 mA / 24 V.
• Sensitivity – 4 levels, set with DIP switches.
• Hold time – 5 minutes or continuous.
• LED – green: detector ready, red: loop occupied.

Things to consider before installation

• Loop – inductance 25–800 µH (recommended 100–300 µH), insulated copper wire, recommended cross-section 1.5 mm². Determine the number of turns from the loop perimeter given in the instructions.
• Feeder – twist the wire ends (at least 20 times per metre), feeder max. 250 m.
• Location – protection rating IP40; the detector belongs in the control unit enclosure.

For two loops, choose the Nice LP22; an alternative is the Came 1-channel detector. Send questions to eshop@saver.sk.
