Nice LP22 magnetic induction loop detector, 2-channel, 24 V

The Nice LP22 evaluates two induction loops laid in the road surface. When a car, motorcycle or lorry stands on or passes over a loop, the detector switches the relay and sends a signal to the control unit. Use it with barriers, gates and in car parks.

Functions

• Presence or direction – each loop reports occupancy separately, or the detector recognises the direction of travel from the order of the loops.
• Outputs – 2 relays with volt-free contact max. 250 mA / 24 V, NO or NC depending on the jumpers.
• Sensitivity – 4 levels, separately for each channel.
• LED – green: detector ready, red: loop occupied.

What to bear in mind before installation

• Loop – inductance 25–800 µH (recommended 100–300 µH), insulated copper wire, a cross-section of 1.5 mm² is recommended. With a loop perimeter of 4–6 m, 4 turns are enough; with 6–12 m, 3 turns; other values are in the instructions.
• Feeder – twist the wire ends at least 20 times per metre, feeder max. 250 m, loop resistance including feeder max. 20 Ω.
• Location – protection rating IP40; the detector belongs in the control unit enclosure.

For one loop the Nice LP21 is enough; an alternative is the Came 2-channel detector. You will find barriers in the Road barriers category. Send questions to eshop@saver.sk.
