Beam of Invisible Light Detects the 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. Operation is not affected by room lighting. Circuit board is 1-1/4 inches wide x 3-1/2 inches long. Requires external 12-16v AC or DC power supply (use the accessory terminals of your power pack or separate transformer). Includes red LED for train indication, plus instructions for advanced circuits, signals and easy installation.

IRDOT-2EW with extended wire-leads 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). Features an on-board relay to isolate switched circuitry and increase maximum switched current to 3a. Use #60748 #2 x 1/2 inch wood screws (sold separately) for mounting IRDOT circuit board to base board. (2 screws required per IRDOT.)
