TE Connectivity Grace Inertia Male Connector Housing, 2 Way, 2.5 mm Pitch, Cable Mount, Nylon, Straight, 2-1971793-3

TE Connectivity’s Grace Inertia Male Connector Housing, model 2-1971793-3, is a specialized wire housing designed for secure, efficient wire-to-board electrical connections in demanding industrial and commercial applications. Featuring a 2.5 mm pitch and 2-way, single-row configuration, the connector housing is expertly crafted from durable nylon for longevity and insulation performance. The cable mount format and straight orientation support streamlined integration into compact assemblies.

The core innovation is the inertia locking mechanism, engineered to guarantee robust mating with audible and tactile confirmation. This patented system simultaneously completes the circuit and locks the connector - helping to eliminate assembly errors such as half-mating. It prevents contact damage, ensures reliable connection integrity, and reduces the likelihood of accidental unmating caused by external forces in environments with vibration or movement.

Grace Inertia 2.5 Mark II connectors are designed with ease of assembly in mind. They reduce contact insertion force by up to 59%, have an ergonomic profile for manual operation, and incorporate lanceless contacts to prevent snagging and entanglement during installation. The dual beam contact design offers stable electrical performance and reduces wear, making this connector housing suitable for frequent maintenance cycles.

This male connector housing features four color-coded keying methods, enabling quick identification and preventing mismatched or blind mating. Terminal Position Assurance (TPA) accessories are available to ensure each contact is properly seated and retained, further enhancing reliability in critical electronics builds. TPA modules and receptacle contacts are sold separately when needed for complex harnesses or panel solutions.

Typical use cases include large electrical appliances and industrial control boxes: air conditioning units, refrigerators, cookers, microwave ovens, dishwashers, and other devices requiring dependable wire-to-board connectivity. Engineers benefit from the compact footprint and enhanced safety features, ensuring compliance and efficiency in high-density PCB layouts and automated production lines.

Additional technical highlights include a housing length of 5.7 mm, width of 10.4 mm, nylon construction for electrical insulation, and compatibility with Grace Inertia Connector 2.5 series. The straight orientation aids in cable routing for modular and rack-based systems.

Compact 2-way, 2.5 mm pitch housing for space-constrained applications. Ergonomic assembly with reduced insertion force and lanceless contacts. Inertia locking mechanism provides secure, audible mating confirmation. Color-coded keying and TPA accessories improve accuracy and reliability.
