Product details

CST-100 II Receptacle Housing for 21-Circuit Harnesses

The single-row layout and locking ramp fastening make this housing suited for harness assemblies that need a positive-lock mate with the matching CST-100 II header, common in appliance, industrial control, and automotive interior applications where vibration can back out an unlatched connector.

Pitch, Positions, and the Locking Ramp Fit

The glass-filled PA nylon housing holds its dimensional stability up to 105°C, which covers the warm side of an industrial cabinet or an automotive passenger compartment.

Contacts Are Ordered Separately — What Fits

No special tooling beyond a standard hand crimper and an insertion tool.

Frequently asked questions

What is the exact pitch of the 2-1375820-1?

This matches the footprint of any mating CST-100 II header with the same position count.

Is the 2-1375820-1 housing keyed or polarized?

The housing uses a locking ramp fastening system, which provides polarization when mated with the matching header — the ramp engages with the header latch in one orientation only, preventing a reverse mate.
