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.
Reliable & easy infrared train detection for model railroads, for all scales
- 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
- Self-aligning component installs in the roadbed between the rails
- Powered directly from other electronics or a filtered 5-16 VDC supply
- 18 inch wires for extra reach
- Onboard LED lights when train is detected — easy to verify installation
- Nothing to adjust
Instant Response Detector Model No. NS-350
Out of stock.
The Instant Response Detector reacts to train arrivals and departures by immediately changing its outputs. This is the Detector for fast acting electronics that expect and can handle brief changes in detection, such as between railcars.
Delayed Response Detector Model No. NS-352
Out of stock.
The red-jacketed Delayed Response Detector activates its outputs instantly when a train is detected. It will hold its outputs active for 2 seconds after the train departs. This prevents outputs from "bouncing" between active and inactive during gaps between railcars. The onboard LED still responds instantly, aiding installation and testing.
