IRDOT-1EW
(InfraRed Detector Of Trains, Extended Wire-Leads)

Beam of Invisible Light Detects Location of Model Trains!

Our Infra Red Detector Of Trains (IRDOT) emits a beam of invisible infrared light through a small hole drilled between the ties of your model railroad track.

When a locomotive or railcar passes overhead, it reflects this beam through the same hole to IRDOT's detector.

This, in turn, triggers a circuit which turns on a light or energizes a relay.

Use it to indicate when a train has reached the end of a hidden siding, is located in a tunnel, has cleared hidden staging yard switches and more.

IRDOT's circuitry is independent of track power and detects both powered and unpowered rolling stock without modification.

IRDOT-EW has separate emitter and detector attached to 18 inch long leads for mounting in tight spaces or for use as a beam splitter (trains break the beam and trip the circuit).
