6.3mm 1P Fast-On Terminal Connectors

Ensure fast, secure, and reliable electrical connections with high-performance Terminal Connectors designed for low-power signal and control applications. The SH6.3QX-1K is a single-pole (1P) quick-disconnect terminal with a standard 6.3mm pitch, engineered for easy installation and dependable performance in a wide range of electronic and household devices. Widely known by its industry-standard equivalent KF250, this connector is a popular choice for manufacturers and service technicians seeking a proven, interchangeable solution for wire-to-terminal connections.

Constructed with a durable Nylon 66 UL 94V-2 flame-retardant insulating body, this connector provides excellent heat resistance, mechanical strength, and self-extinguishing properties in the event of overheating. This makes it ideal for use in safety-sensitive environments such as kitchen appliances, heating systems, power tools, and consumer electronics where long-term reliability and fire protection are essential.

The SH6.3QX-1K is rated for a maximum of 125V AC/DC and 1.0A per contact, making it perfectly suited for low-current circuits including control signals, indicator lights, sensors, and switch connections. Its compact 1-pole design allows for space-efficient wiring in tight enclosures and crowded control boards.

This connector supports wire sizes from 20 AWG to 14 AWG, accommodating a wide range of stranded and solid copper wires commonly used in internal wiring systems. The fast-on (also known as quick-connect or blade) design ensures tool-free, secure mating with corresponding female terminals, enabling rapid assembly, easy maintenance, and hassle-free replacements—critical for both production lines and field repairs.

Common applications include microwaves, coffee makers, air conditioners, washing machines, lighting fixtures, and automotive auxiliary circuits, where consistent and safe electrical connectivity is required.
