XM-LECG is a straight fixed receptacle designed for twin-nut panel mounting and direct PCB installation. It features a female mating interface with straight male PCB pins at the rear.
The threaded mounting body, two fixing nuts and lock washer provide secure installation through an equipment panel. A standard G alignment key supports accurate connector mating, while A–M and R keying options are available for configurations requiring protection against cross-mating.
