Solder cup headers and sockets

16 May 2018 Interconnection

Mill-Max has produced new 1,27 mm pitch solder cup headers and sockets for termination of fine-gauge wires and cables. These solder cup connectors are ideal for applications that demand a highly reliable interconnect in a compact format, such as medical and industrial equipment.

The headers and sockets each feature closed cavity pins and receptacles providing isolation between the soldering and interconnect areas; keeping solder from contaminating the pin and socket connection. The solder cups are uniformly aligned to facilitate efficient soldering, especially useful for terminating cables, and can accept up to #26 AWG stranded wire. The male headers have 0,41 mm diameter tails suitable for mating with all Mill-Max 1,27 mm pitch SMT and through-hole board mount sockets, suitable for making wire-to-board connections.

The socket receptacles are a two-piece construction with a precision-machined outer shell and stamped beryllium copper internal contact designed for repeated mating while maintaining reliable contact over the life of the product. The insulator material is high performance Nylon 46 with excellent chemical resistance, mechanical strength and an HDT of 290°C to withstand most soldering processes. The standard plating option is gold, providing interconnect reliability, corrosion protection and wear resistance.

Connectors are available in single- and double-row configurations with up to 50 or 100 positions, respectively.
