Installation
The Infra-Red sensor is normally installed below the track-bed.
The detection range of the unit is up to approximately 25mm from the face of the
package when the default sensitivity is set (for dark surfaces with low levels of
reflectivity).
The detector can be mounted in an 8mm hole drilled through the track baseboard. If
required, the detector can be held in place using a small amount of blutack,
expanded polystyrene or similar.
The led diameter is 2.2mm, so on smaller scales the leds can still have a clear view
between the sleepers.
