12-Position Plug Housing with CPA
The 638394-5: It is a free-hanging (in-line) housing designed for crimp termination — the contacts are ordered separately and must be inserted after crimping to the wire. The housing is molded from glass-filled PBT in black, with a latch holder fastening system and a Connector Position Assurance (CPA) feature that provides a secondary lock to prevent accidental unmating in high-vibration environments. This is a wire-to-wire or wire-to-board interconnect, typically used in automotive, industrial control, and appliance harnesses where a reliable, field-serviceable connection is required.
Housing Specs and Termination
This is a plug housing — it accepts female socket contacts that are crimped onto the wire. The latch holder provides primary retention; the CPA clip engages over the latch to keep it locked even under cable tug or machine vibration. The free-hanging mount suits inline harness splicing or panel feed-through where a PCB header is on the other half.
