5001 – KEYSTONE

The KEY 5001 is a single-pole, non-shielded test point designed for PCB-level signal access. It features a black, molded thermoplastic housing, providing insulation and a visual indicator. The component is intended for through-hole mounting with a pin diameter of 0.040 inches (1.02 mm), accepting standard test probes for in-circuit testing and signal monitoring. The 5001 offers a low-cost solution for temporary connection points, facilitating troubleshooting and validation during development and production. Its construction allows for repeated insertions and removals of test probes without compromising electrical contact. The part is typically manufactured from a brass alloy with a tin or nickel plating to ensure reliable solderability and corrosion resistance. It is designed for general-purpose testing applications where signal integrity is not a primary concern.
