6.3mm 1-Pole High-Current Terminal Connectors

Ensure robust, long-lasting electrical performance with high-power Terminal Connectors engineered for superior conductivity and safety in demanding applications. The SH6.3ZC-1P is a single-pole (1P) connector with a 6.3mm pitch, designed for secure PCB mounting and reliable wire termination in power delivery systems. Universally recognized by its industry equivalents 172076-1 and 630591, this terminal block ensures seamless compatibility across global manufacturing platforms, making it a trusted choice for industrial, automotive, and consumer electronics applications.

Constructed with a PA66 UL94V-2 flame-retardant housing, this connector delivers excellent thermal stability, mechanical strength, and resistance to ignition. The high-performance nylon 66 material maintains structural integrity under continuous operation and elevated temperatures, making it ideal for use in environments where safety and durability are paramount.

Unlike standard low-current variants, the SH6.3ZC-1P is rated for a maximum of 250V AC/DC and an impressive 12A per contact, making it suitable for medium-power circuits such as motor controls, power supplies, lighting drivers, and heating elements. The high current capacity is achieved through precision-engineered internal components made from tin-plated brass, including the pin and solder tabs, which ensure low contact resistance, excellent conductivity, and strong resistance to corrosion and thermal fatigue.

This connector supports wire sizes from 24 AWG to 14 AWG, offering flexibility for both fine and heavy-gauge wiring. The solder-tab design allows for secure and permanent attachment to printed circuit boards, ensuring stable mechanical and electrical connections even under vibration or thermal cycling.

Common applications include LED lighting modules, power adapters, industrial control panels, home appliances, and automotive electronics, where reliable power transmission is critical.
