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.","metaTitle":"TE 1438894-2 Fakra Lock, Gray PBT, Active","metaDescription":"TE Connectivity 1438894-2 Fakra lock accessory, gray PBT body, for SMB/Fakra connectors.
