Here's the description of each pin of the LM61:

LM61 TO-92 package, bottom view, with +Vs, Vout and GND pins labelled LM61 sensor wired with red, yellow and black wires, heat-shrink tubed

In the example image, +Vs is connected to RED, Vout to YELLOW, GND to BLACK wire.

It must be connected to the MAIN port of your controller—the MAIN is a female DB9, so you'll use a male connector; the exact pins differ between versions of the controller.

  • For the original Seletek, Armadillo or Platypus:
    • +Vs goes to DB9 pin 5
    • Vout goes to DB9 pin 9
    • GND goes to the shell of the DB9
  • For the Armadillo2, Platypus2, Tarsier or Limpet:
    • +Vs goes to DB9 pin 8
    • Vout goes to DB9 pin 9
    • GND goes to the shell of the DB9

If you are doing this in a motor cable—quite convenient—then, using another 5-wire cable, connect pin 1 to 4 and shell in both the male and female DB9 plugs.

So, for a motor and temperature sensor cable, there are 3 ends:

  1. DB9 male end (will plug into the controller): you'll have the temperature sensor (to whatever pins depending on the version) and the 1 to 4 and shell soldered to a cable going to…
  2. DB9 female end (will plug into the motor): just pins 1 to 4 and shell connected to the male end.
  3. Temperature sensor end: just 3 wires to the DB9 male end as explained.
