Overview

The M50-1900005 is a high-density jumper socket designed for use with 1.27mm (0.05 inch) pitch male headers. Part of Harwin's Archer M50 series, this fine-pitch shunting connector provides a reliable method for manual configuration or hardware strapping in space-constrained designs. It features a gold-flash plated copper alloy contact housed in a UL94V-0 PBT plastic body for durable performance over 300 mating cycles.

Why Choose This Part

The 1.27mm pitch offers a significant space saving over traditional 2.54mm jumpers while maintaining a 1A current rating. Its gold-plated contacts ensure low contact resistance of 20 milliohms and long-term reliability against oxidation in industrial environments. The 3mm height profile and open-top design make it easy to manipulate with tweezers in dense layouts.

Applications

Hardware Configuration
Used as a physical switch alternative to enable or disable specific PCB features, such as boot modes or pull-up resistors.
Bus Termination
Acts as a removable bridge to apply termination resistors on communication lines within compact embedded systems.
Prototyping and Debugging
Allows developers to quickly isolate circuit segments or bypass components during the hardware bring-up phase.
