The TE Connectivity 1438894-2 is a secondary lock accessory for the SMB / Fakra connector family. It snaps onto the connector body to retain the terminal and prevent back-out under vibration — a standard requirement in automotive RF harnesses where the connector sees engine-bay or chassis-mounted duty. The gray PBT body is color-coded for the Fakra keying scheme, so it matches a specific housing cavity and prevents cross-mating with other Fakra colors in the same bundle.
No last-time-buy or end-of-life notice applies.
Compatibility and installation note
The lock is designed for use with SMB and Fakra connectors. It engages with the housing latch feature after the crimped terminal is fully seated — the lock then prevents the terminal from backing out during cable flex or thermal cycling. No special tooling beyond the standard Fakra crimp and insertion tooling is needed; the lock simply snaps into place by hand.
