HARWIN Closed Top 2 Way 1 Row 2.54 mm Pitch Jumper Straight Female Blue 250V 3A M7687-05

The HARWIN M7687-05 is a high-quality closed top jumper designed specifically for printed circuit board (PCB) applications requiring 2 way 1 row connectivity at a 2.54 mm pitch. This jumper socket offers a closed top design which protects the contacts and supports reliable on-board programming and configuration.

Made from blue polybutylene terephthalate housing material, it ensures excellent insulation and mechanical durability. The internal contacts are composed of phosphor bronze with gold plating, which enhances corrosion resistance and maintains low contact resistance rated at a maximum of 25 milliohms.

Rated for use at 250 volts and 3 amperes current, this jumper is suitable for low voltage electronic circuit control and signal routing. The straight orientation and female connector gender provide straightforward and versatile hooking to male pin headers on PCBs.

Its compact size with a length of 10 mm, width of 5 mm, and a depth of 2.4 mm enables dense packing on circuit boards while maintaining functional reliability. The design supports up to 300 insertion and removal cycles, ensuring long-term usability in industrial, laboratory, electronic manufacturing, and repair environments.

This model belongs to the M20 series jumpers with color-coded housings that facilitate identification and efficient installation. Produced in the United Kingdom, it meets industry standards for quality and performance.
