Compression Mount Spring-Loaded Connectors (SLC)

Mill-Max's SLC with two working plungers provide adjustable connections between mating components

Image of Mill-Max's Compression Mount Spring-Loaded Connectors (SLC)Mill-Max's solderless, compression style, spring-loaded connectors have two active plungers and are designed to utilize hardware to secure them in place. Since no soldering is required, they facilitate easy adjustment and flexibility during assembly, and removal and replacement are simplified.

The 858-22-00X-80-XX1101 and 858-22-00X-80-XX2101 connectors are additions to Mill-Max's 4 mm pitch rugged spring-loaded series. They are the first Mill-Max connectors to incorporate spring pins with active plungers at each end. This unique feature makes these connectors ideal for situations in which a soldered connection is not desirable or may not be possible due to design constraints such as temperature considerations, stack up tolerance issues, or where ease of assembly and disassembly is required. With spring-loaded plungers as the interface at both ends, the connector is sandwiched between two mating surfaces using screws to compress the plungers on the base end, eliminating the need for soldering. The opposite end plunger then acts as any other spring-loaded connector, ready to engage with a mating device or board.

Environments such as in medical or research applications, where devices and mating surfaces must be wiped down and cleaned regularly, are excellent uses for solderless, compression connectors as they are easy to assemble and disassemble. Test fixtures are also a good fit as over time the connector will need to be replaced and this is done easily without de-soldering. A variety of board stacking applications as well as docking stations, quick connects, or any assembly that relies on a mechanical means to secure the device to the dock or stationary end are well-suited for these connectors. There are two plunger travel arrangements available: 0.045” stroke for both plunger ends or 0.030” on base end and 0.060” on the device end. Both are single-row and are available with or without alignment pins and threaded inserts. The rugged spring pins are rated for 9 amps and with stainless steel springs, capable of maintaining spring force at elevated temperatures over time.
