HARWIN 7.25 mm Surface Mount Beryllium Copper Alloy Grounding Contact S1951-46R

HARWIN S1951-46R grounding contact is a 7.25 mm high surface mount component crafted from beryllium copper alloy, designed especially for PCB grounding and RFI shielding applications. This contact features a simple C-style spring design that ensures robust spring properties and positive contact with metal shields or chassis parts on surface mount PCBs.

The contact's plating of tin over nickel provides excellent corrosion resistance, while its low contact resistance of 20 milliohms guarantees optimal electrical performance for currents up to 7 amperes. It measures 7.25 mm in height, 9.59 mm in length, and 5.7 mm in width, making it compact for use in confined spaces or blindmate applications.

The multi-directional spring feature supports both vertical and horizontal operation, making this contact highly adaptable for wiping and sliding actions. It is suitable for automated assembly with standard placement equipment, enhancing production efficiency.

Typical use cases include POS systems, home entertainment devices, industrial process control equipment, motion control units, and mobile power applications, where reliable grounding and RFI immunity are critical.
