Automatic Opening/Closing Induction Loop Detector 12V DC Presence and Pulse Relay (12 Volt Version)

The Single channel loop can be used for either a pulse to command operation (upon detection latches the relay) or a presence command (typically as a safety device to hold the relay til clear). With four adjustable sensitivity setting + sensitivity boost feature the loop detector can be fine tuned to suit the installation. The frequency is also adjustable to prevent cross talk between multiple loops in close proximity to one another.
