399 Series Spring-Loaded Target Connectors

Mill-Max 399 Series Spring-Loaded Target Connectors come in single-row strips with a concave face, offering an improved interface for misaligned connectors. The concave face also provides more surface area for mating with Mill-Max standard 0.042" diameter plungers. The target connectors utilize a gold-plated conductive path back to the board-mounted spring pin connector. Mill-Max 399 Series Spring-Loaded Target Connectors use MM #1947, #1948, and #1960 pins with insulators that are high-temperature thermoplastic.
