3.3 Centerline GRACE INERTIA connectors

Fewer assembly errors, better connections

3.3mm pitch GRACE INERTIA connector employs an inertia locking mechanism for easier, reliable connections.

3.3mm pitch GRACE INERTIA (3.3 GI) connectors are great solutions to help eliminate human error during assembly. GRACE INERTIA connectors employ an inertia locking mechanism that simultaneously completes the circuit and then “locks” the connector, helping to provide ideal mating reliability and prevention of mismatching. Use of an optional terminal position assurance device (TPA) helps to ensure the contacts are fully inserted into the housing and do not back out. The header provides a PCB to contact height of 8mm, which prevents urethane coating from flowing into the housing. This is particularly advantageous for applications such as washing machines.
