TCRT5000 IR Sensor Reading Head, Incremental Encoder

This design houses 2x TCTR5000 IR Sensor PCBs.
It is a perfect design for building an Incremental encoder (e.g. an Arduino Hamster Wheel reader) or to allow a autonomos car to follow a black line.
Holes in the lid allow to adjust sensor sensitivity and allow to see the status LEDs.
The cable can be strain reliefed with a Zip-tie.
The Lid can be closed with 2x M3 x 20mm countersunk screws
