TE Connectivity Mini-Universal MATE-N-LOK Series Straight Through Hole PCB Header 2 Contacts 4.14 mm Pitch 600V 1-770166-0

The TE Connectivity 1-770166-0 is a Mini-Universal MATE-N-LOK series straight through-hole PCB Header ideal for robust and dependable electronic connections. This connector is engineered with 2 tin-plated brass contacts featuring a 4.14 mm pitch, arranged in a single row and housed in white, flame-retardant UL94V-0 nylon. Its shrouded, positive latch mechanism ensures secure mating, helps prevent accidental disconnects, and maintains reliable performance under vibration and movement.

Designed for wire-to-board solutions, this header is perfect for applications requiring stable power and signal delivery, with contact male pins suitable for solder termination on standard PCBs. With a maximum current rating of 9.5 A and voltage handling up to 600 V, it is appropriate for both low- and medium-power tasks in industrial controls, instrumentation, and other electronics requiring a rugged, versatile interface. The through-hole mounting ensures full mechanical strength and stable placement, supporting automated assembly processes.

The durable nylon housing provides excellent thermal and chemical resistance, with an operational temperature range from -55 °C to 105 °C. The compact form factor accommodates boards with limited space while ensuring correct pin alignment and PCB retention. The inclusion of board locks and a shrouded construction adds further mechanical security for high-reliability environments.

This header integrates smoothly into systems built around TE Connectivity's Mini-Universal MATE-N-LOK connector ecosystem. Typical use cases include power and signal routing in automation panels, process controls, electrical distribution boards, as well as test and measurement devices where secure, repeatable connections are essential.

For compatible mating connectors, pair with corresponding Mini-Universal MATE-N-LOK plug housings and socket contacts. Accessories such as strain reliefs or dust covers enhance the lifespan and robustness in demanding environmental conditions.
