2.5 Centerline GRACE INERTIA connectors

Eliminate half-mating, and back-out errors

2.5mm pitch GRACE INERTIA connectors feature advanced design concepts to help eliminate connection issues.

TE’s next generation GRACE INERTIA connectors with 2.5mm pitch, GRACE INERTIA 2.5, feature advanced design concepts to facilitate more stable, reliable and durable connection.  The inertia locking mechanism prevents defective products caused by half mating and helps prevent connectors from being disconnected during movement or transportation. The Terminal Position Assurance (TPA) helps to ensure that the contacts are properly seated in the housing and provides an extra measure of protection against contact back-out. The new design structure also reduces contact insertion force by as much as 59% during assembly. Ergonomic design and lanceless contacts, which prevent snagging or entanglement, improve safety and efficiency during operation. Housings and headers meet Glow Wire test (GWT) requirement per IEC 60335-1 5th ed. (750°C, without flame), plus the flammability requirements of UL 94 V-0.
