I have a combination of sensors with that aviation connector. I am trying to figure out the pin out. I plan to power my sensors with 24 vDC.
All I have come accross so far is in the Liquid level Sensor datasheet which says:
Pin 1 - If powered via 12v connect this pin
Pin 2 - If powered via 5v connect this pin
Pin 3 - RS485A
Pin 4 - RS485B
Pin 5 - GND
