Error Proof Assembly with Inertia Locking

The GRACE INERTIA connector series supports wire-to-wire and wire-to-board systems with a product portfolio that includes 1.25 to 12.4mm pitch connectors with maximum current ratings ranging from 1 to 20A. The defining feature of these connectors is an inertia locking mechanism that locks the connector into place when the circuit is completed. This feature can improve mating reliability and reduce the need for complicated inspection processes. Additional features include lance-less contacts to prevent tangled wires and multiple color and keyed connector options to reduce assembly error. GRACE INERTIA connectors are used in power and signal applications, including appliances, transportation, and lighting.

Featured Products

Signal GRACE INERTIA 2.0 Connectors

Utilizing IDC technology, the 2.0mm Signal GRACE INERTIA (SGI 2.0) connector family can help you achieve higher efficiency and assembly cost savings. SGI 2.0 miniaturized connectors offer 2 through 10 positions in a single row configuration and are rated up to 3 amps and 50 volts AC.


GRACE INERTIA 2.5 Connectors

 The 2.5mm GRACE INERTIA connector features advanced design concepts to facilitate more stable, reliable and durable connection. The new design structure also reduces contact insertion force by as much as 59% during assembly.


GRACE INERTIA 3.3 Connectors

3.3mm pitch GRACE INERTIA (3.3 GI) connectors are great solutions to help eliminate human error during assembly. The header provides a PCB to contact height of 8mm, which prevents conformal coatings from flowing into the housing. This is particularly advantageous for applications such as washing machines.


GRACE INERTIA 6.0 Connectors

TE offers 6.0mm GRACE INERTIA connectors with maximum current rating of 10A. These connectors offer error-resistant mating and strong latching for mid-power connections.
