1990s PIR: PT06A-12-10S amphenol connector or PT06W-12-10S with a MS3420-4 and MS3420 sleeve 1990s PIR pin outs:

    • A radiometer thermopile low - black
    • C radiometer thermopile hi + red
    • D case thermistor required - white
    • E case thermistor required - green
    • F dome thermistor optional - brown
    • G dome thermistor optional - blue
    • H Case ground (shield?)
    • J not used
    • K not used
    • YSI 44031 (thermistor model)

1980s PIR: PT06W-10-6S amphenol connector with various MS3420 sleeves

  • oldest 1980s (?) PIRs: Emily asks: What are the pinouts for these units? Answer from Eppley:

It depends on the age of the PIR as the 6 pin connectors were used before the dome thermistors were included standard and then we switched to the 10 pins. However, certain customers continued to request the 6 pin in some cases. The wiring of the 6 pin PIR is probably:

    • A: Thermopile (-) black
    • B: Thermopile (+) red
    • C: Case Thermistor required white
    • D: Case Thermistor required green
    • E: Instrument Ground or Dome Thermistor brown
    • F: not used or Dome Thermistor blue
    • Shield is the Ground
  • Belden Cable 6 conductor twisted and shielded 20 or 22 awg

After a field trip to Upper Kuparuk Met on 7/7/2017, I found that the Pinouts that were sent to me by Eppley were incorrect. I guess it really does depend on the age of the PIR. This is what I found:
