Model Railroad Infrared Train Detection
If something can be activated with a switch, it can be automated with a train detector!
|
|
Train Detectors
- Pulsed infrared proximity sensors for detecting model trains on the track.
- May be used as a reflective detector (sensors in the roadbed) or as an interrupt detector (detector looks across the track).
- Relay contact triggers crossing signals, trackside signals, panel lights or action accessories.
- Automatically switch track power, see the how to automatically stop trains and the collision avoidance at track crossings pages.
- Sensors can be used with the room lights on or off, and do not require overhead light sources.
- No rail gaps required, no modifications to rolling stock.
- Detectors also available with USB computer interface
