Overview
The 22-01-3037 is a 3-position crimp housing from the Molex KK 254 series, designed for versatile wire-to-board connections. It features a 2.54mm (0.100 inch) pitch and a friction-locking ramp to ensure secure mating with standard headers. This natural white nylon housing is a staple in embedded electronics for low-power signal and power distribution.
Why Choose This Part
The housing is keyed to prevent mis-mating and includes a friction lock for vibration resistance in mobile applications. Its 2.54mm pitch is compatible with standard 0.1-inch pin headers, making it one of the most accessible and widely supported connector systems in the industry. The UL 94V-0 rated nylon material provides excellent insulation and durability for commercial environments.
