The 770077-1: It is a single-row, panel-mount, snap-in housing with a 5.03mm pitch, designed for crimp-terminated contacts. The natural nylon insulator carries a detent lock for vibration-resistant mating. This housing is typically used in power distribution and harness assemblies for appliances, automotive interiors, and industrial control cabinets where the.093" contact family provides reliable current handling at 5.03mm spacing.
The 5.03mm pitch (0.198") is the centerline spacing for the crimp contacts — wide enough to handle moderate power without creepage concerns, but tight enough to keep the connector compact for a 4-circuit run.
The Commercial.093" Pin and Socket series uses standard.093" diameter pins and sockets, typically 14-20 AWG.
How It Stacks Against a Same-Series Sibling
The closest peer in the same Commercial.093" family is the 1-1644055-3, a 6-position plug with a 6.35mm pitch and two rows. The 770077-1 is a single-row, 4-position housing at a tighter 5.03mm pitch — choose the 4-position when your circuit count is lower and you need a narrower connector footprint. The 6-position sibling also uses a latch holder instead of a detent lock, so the retention mechanism differs.
