TE Connectivity Grace Inertia Series PCB Header 3 Contacts 2.5 mm Pitch 1 Row Shrouded Straight Through Hole 50V 3-1971800-1

TE Connectivity’s Grace Inertia Series PCB Header 3-1971800-1 is a precision-engineered wire-to-board connector solution designed for demanding electronic applications. Featuring three contacts and a compact 2.5 mm pitch, this through-hole header is shrouded for mis-mating prevention and offers an ergonomic design optimized for reliable manual assembly.

This header integrates an inertia locking mechanism, simultaneously completing the circuit and ensuring a secure connection. When properly mated, it produces an audible 'click' confirming the connection, while its shrouded housing prevents defective products caused by half-mating, thus enhancing assembly quality. If improper mating is attempted, contacts are prevented from making contact, further reducing errors.

Constructed with high-quality nylon housing, copper alloy contacts, and tin plating, the header supports a robust 3A current rating at 50V maximum voltage, suitable for diverse wire-to-board signal and power requirements. Locating pegs at the base enable precise alignment during PCB installation, while the reduction in contact insertion force - up to 59% compared to earlier designs - improves assembly efficiency and operator comfort.

The Grace Inertia Series is designed for use across a wide range of industrial, consumer, and commercial products, including air conditioning units, refrigerators, cookers, microwave ovens, dishwashers, and control boxes. Its performance parameters ensure reliable operation in environments from -30°C up to 105°C, making it adaptable for many electrical and electronic systems.

Key applications include industrial control, HVAC systems, consumer appliances, and electronic manufacturing. Engineers appreciate its color-coded keying for accurate identification and blind mating avoidance, as well as its ergonomic features that foster efficient and error-free production lines.

Inertia locking mechanism prevents accidental unmating and ensures connection reliability. Compact, space-saving form factor with 2.5 mm pitch. Durable nylon housing and copper alloy contacts for long service life. Precise alignment on PCB with locating pegs and straight orientation for streamlined assembly.

Supports up to 3A current at 50V, suitable for a vast array of signal and power interface applications. Browse more TE Connectivity PCB Headers and wire-to-board solutions in the EnvMart Electronics Components category.
