PRECISION Trackside Detector Manual v4.2a

N Scale Installation Video

The Precision Detector from Model Train Technology is the first type to be impervious to all types of room (ambient) lighting conditions.  You can place it any where in any kind of lighting condition. It never needs adjustment or tuning for changing light conditions. The Precision Detector has a 1.0 mm level of precision.  You can set it to detect only the train on a specific track and not the one farther or near one.

The Precision Detector works with Z, N, HO and O/S.

Note: for connecting to NCE AUI-01 a common ground connection must be made.  You can order the extra GND wire to be attached.  MOST PEOPLE DON”T NEED THIS.


A flush bracket is included along with a scale electrical box (shown below).

  1. Kevin Paige

    Best detector I have ever used. Works in all kinds of light straight out of the box. Very easy to program and so flexible in the design – provides excellent detection for all my track scenarios. Used to provide block signaling on my mainline and it worked perfectly. Auto calibration feature is a great plus.

    Just wanted to thank you for a great design. I finally got the time to finish my project and I am truly very happy with the results!
    Your sensors worked perfectly in my Adduino project to police traffic on my layout!
