Sensors

The IR transmitters and receivers are Shinkoh Electronics P/N KB893, which have been discontinued.

Cable Harness Connectors

The items below are to mate with the stock harness.

Quantities listed below are for both sides.

Sensor Connector

  • YLR-15V Qty 2
  • SYM-01T-P0.5A Qty 26 (26-20 AWG) OR SYM-41T-P0.5A Qty 26 (20-16 AWG)

LED Connector

  • YLR-06V Qty 2
  • YLS-03V Qty 4
  • SYM-01T-P0.5A Qty 6 (26-20 AWG) OR SYM-41T-P0.5A Qty 6 (20-16 AWG)

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).
