This is the two-circuit end of the series — the smallest member, used for simple power or signal pass-through where you only need one or two circuits.
The Contacts Trap — Order Them Separately
The listing explicitly states contacts are not included. The crimp termination means you'll need the correct application tooling for your wire gauge; the housing itself has no contacts loaded. A common rookie mistake is ordering just the housing and wondering why the harness doesn't conduct.
Mating Half and Locking Feel
The friction lock provides a positive but light retention — it won't rattle loose under normal vibration, but it's not as aggressive as a locking ramp. For comparison, the sealed 1-1703532-1 from the same series uses a locking ramp for higher vibration environments. If your application sees heavy shock or continuous vibration, consider whether the friction lock is enough or if you need the ramp-style mate.
