This connector accepts unmodified ISO 8877 8P8C modular connectors (often called RJ45 connectors or Ethernet “Cat 5/6” connectors).
When used in hostile environments, a standard Ethernet cable can have a mating environmental shield (Amphenol part number RJF6MN) fitted.
This is a standard 4-pin military-specification bayonet plug, conforming to MIL-DTL-26482 (formerly MIL-C-26482).
10-36 V DC input
Wiring details for the compatible socket as seen from the cable end (i.e. when assembling).
Caution: Observe the correct polarity when connecting the power supply. The red lead (from pin B) must be connected to the positive terminal, typically labelled ‘+’, and the black lead (from pin A) must be connected to the negative terminal, typically labelled ‘-’. An incorrect connection risks destroying the digitiser, the power supply and any connected instruments.
This is a 14-pin LEMO EEG.1K socket. Suitable mating connectors can be found in the LEMO FGG.1K.314 range.
