2-1971793-3 is a 2-position GRACE INERTIA 2.5mm pitch plug housing connector featuring red keying (Key C) for reliable wire-to-board signal conduction. This second-generation connector incorporates an inertia locking mechanism that prevents disconnection during movement or transportation and eliminates defective products caused by half-mating. The housing is constructed from UL94-V0 rated nylon with tin-plated copper alloy contacts, operating at 50V AC/DC with a maximum current rating of 3.0A and temperature range of -30°C to 105°C. The connector features lanceless contacts to prevent snagging, dual beam contact design for enhanced reliability, and Terminal Position Assurance (TPA) to ensure proper contact seating. This product is ideal for large and small home appliances, industrial control systems, and other applications requiring stable, durable connections with reduced assembly complexity.
