Rugged 4 mm Pitch Spring-Loaded Connectors

Mill-Max features a ruggedized long stroke 4 mm pitch spring-loaded connector (SLC) that is aimed at tough applications in rough environments

Image of Mill-Max's Rugged 4 mm Pitch Spring-Loaded ConnectorsMill-Max's 858 series is ideal for applications where the connector will experience side loading, great variation in vertical engagement, high levels of shock and vibration, high cycle counts, and extreme temperatures.

Mill-Max's 858 series features heavy-duty spring pins with 0.050” (1.27 mm) diameter plungers that resist bending during the application of side loads. The gold-plated stainless steel spring ensures reliable operation over 1 million cycles and is less prone to stress relaxation when operating at higher temperatures over time (260°C maximum at 1 hour, 180°C maximum at 24 hours).

Offered in through-hole, SMT, and SMT with alignment pin versions, the 858 series features a high temperature molded Nylon 46 housing that is compatible with RoHS soldering processes. Mounting tabs, integrated into the housing, provide a means for secure attachment to the PCB or product assembly. The tab holes may be specified with threaded inserts or left empty for other hardware requirements. The flanged base provides stability.

In common with all Mill-Max products, the SLCs employ high-speed precision turning with extremely tight tolerances. Established in-house manufacturing and assembly techniques produce a reliable, low resistance, and consistent performance spring pin. Extensive testing and screening ensures that only high quality spring pins are used in these connectors.
