The NightScope™ Infrared Detector reliably senses trains in all lighting conditions.
Just 3 inches long and less than 3/8 inches in diameter, the Detector mounts below your track with two small holes in the ballast between the rails.
When a train is present, the Detector activates its two opposite-polarity outputs, "Detect High" and "Detect Low".
These outputs are designed to drive a wide variety of popular model railroad electronics.
Realiable & Easy Infrared Train Detection
- Independent of layout lighting: bright, dim, or no light
- No false triggering from other light sources (including infrared)
- No changes to track wiring, locomotives, rolling stock - no gaps to cut, no resistor wheel sets, no reflectors!
- Perfect for night operations
Unlimited Model Railroad Applications
- Two outputs of opposite polarity deliver 200 mA each when activated - enough to directly drive relays, switch motors, or dozens of LEDs
- Directly drives inputs to model railroad electronics from Digitrax, C/MRI, Logic Rail Technologies, ITT Sound Modules, and others
- Delayed Response Detector holds outputs 2 seconds after train departs
- Great for computer control applications
Simple Installation
- Self-aligning component installs in the roadbed between the rails
- Powered directly from other electronics or a filtered 5-16 VDC supply (not included)
- 18 inch wires for extra reach
- Onboard LED lights when train is detected - easy to verify installation
- Nothing to adjust
Instant or Delayed Response
- Instant Response is for fast acting electronics that expect and can handle brief changes in detection, such as between railcars.
- Instant Response should be used with the HotShot Speedometer.
- Delayed Response for 2 seconds prevents outputs from "bouncing" between active and inactive during gaps between railcars.
- Delayed Response is not recommended for use with the HotShot Speedometer.

NightScope Infrared Detector mounts between the rails and beneath the roadbed, as in this view of HO track on cork roadbed.
Passing rail cars reflect infrared pulses back to the sensor, triggering the Detectors outputs.
With no rail car present, infrared pulses are not reflected back to the sensor.
