DOMOTIME LD112 Magnetic Loop Detector for Automation

The Domotime LD112 Single Channel Magnetic Loop Detector can manage a magnetic loop and provide an output signal when a reasonably sized metal body (car, motorbike, etc.) travels over the loop. This also allows the control of devices such as traffic lights, gates, barriers, etc. The detector is equipped with two relays:

Relay A: When the loop detects a vehicle, the detector will keep relay A on as long as the vehicle is on the loop;
Relay B: When the loop detects a vehicle, the detector switches relay B with a pulse, even if the vehicle is still detected on the loop.

The detector is also adjustable in both frequency and sensitivity. The frequency setting allows you to install multiple detectors next to each other without causing interference. The sensor also has a "frequency filter" function, which allows you to change the frequency yourself in case it is disturbed by other devices. The sensitivity setting allows the sensor to be selective about the size of metal body that can be detected by the loop. The detector has an automatic sensitivity increase function that automatically changes the sensitivity under certain circumstances
