The Track Sensor incorporates an infrared sensor which detects a train going over it and the output can be used to control and display occupancy for other products in the Layout Link Family - this new Plus version also has additional outputs for direct connection to LEDs and other non-Layout Link items and is supplied with an LED and comprehensive instructions.
A Track Sensor is located next to the track and features a built in infrared sensor which senses a train passing and easily links to and controls a range of Layout Link products using just a single wire which plugs in - no soldering required.
Note: The original ST1 Track Sensor has been superseded by this ST10 which does all ST1 functions plus 4 additional outputs for LED train, occupancy, spark effects etc.
Although the ST10 is designed to just clip or wire into OO/HO track, it can also be used with N Gauge track. To achive this, a small piece of sleeper needs to be cut away from the track to allow the sensor to sit near the rails.
 
You can use a Track Sensor to:
Link to a Mimic Switch or Light to show trains passing or locations
Link to a Sensor Signal to change the following block section signal status
Control a Ground Position shunt signal to change as the train passes
Change a Semaphore signal automatically using the SC300 Dapol controller
Trigger the LC10 / LCN10 Level Crossing lights and sounds when a Train approaches
 
New Track Sensor Plus features:
Track Sensor plus features additional solder terminal outputs to link directly to devices such as LED (included), solid state relay, computers (e.g. Raspberry Pi, Arduino).
 
The 4 additional outputs on the ST10 Plus version are:
Output as a train passes over sensor with occupancy when linked with other Track Sensors or Sensor Signals
Output pulses as train passes over sensor with occupancy when linked with other Track Sensors or Sensor Signals
Random flashes as train passes - like sparking from electric trains or a photographer
Turns on and off between alternate trains
