Sensors

While the part number on the IR transmitters and receivers is not marked on the part, our best guess is Shinkoh Electronics KB893.

Pinouts

The outputs are split between the two towers, so each has 3. Starting from the lowermost beam to the uppermost beam, the order is as follows:

  • Pin 8, right tower
  • Pin 8, left tower
  • Pin 9, right tower
  • Pin 9, left tower
  • Pin 10, right tower
  • Pin 10, left tower

Note pin numbering is right to left, so pin 8 is the central pin of row 2, pin 10 the leftmost pin of row 2, and pin 9 is between them.

The pinout is annotated, left to right, top to bottom, as so: 5V, TOWER, TOWER, TOWER, TOWER, TOWER, TOWER, OUTPUT, OUTPUT, OUTPUT, GND, GND, NC, EARTH. The pins marked 'tower' connect to the other air tower on the other side, so pin 2 -> pin 2, pin 3 -> pin 3 and so on. Outputs are where the state of the tower can be read from (order to be checked).
