Tiny Encoders for DC motors

Hi again! Today I'll show you a small part of a project that I did a long time ago and, due to some changes of plans I didn't end up using. Anyway, maybe this small project might come up handy for you.
Some time ago I went to a junkyard to salvage two powerful high torque DC motors from car window lifting systems to use in a robot and had to make some encoders to put in them. The space where I could put them was really small so I had to find really small sensors and design a PCB for them in Kicad.
The sensors that I used were Vishay's TCUT1300 IR Transmissive Sensor with photo-transistor output. Following the sensor's datasheet I designed a small board (10x8mm) that would fit in the space that I had available.
