It uses a 6.00 mm pitch with an 8.10 mm row spacing, giving it the footprint for a mid-current power interconnect in a harness assembly. The housing is free-hanging (in-line), mates with the matching Power Triple Lock receptacle, and secures the pair with a latch holder.
The 6.00 mm pitch and 8.10 mm row spacing set the mating envelope — the receptacle and any panel cutout must match these centres. The 2-row layout carries 6 circuits in a compact width, which is typical for a power distribution tap or a motor interconnect. The -55°C to 150°C operating range means the housing material (polyamide) is formulated for sustained heat; it will not soften or creep at the temperatures a high-current terminal sees under load.
The mating half is the Power Triple Lock receptacle housing (same series), which carries the male blade terminals. The latch holder on the plug side locks onto the receptacle's mating latch, so the pair stays mated under cable strain and vibration. Crimp termination means you can build the harness at the bench and then snap the contacts into the housing; field replacement is a re-crimp operation.
