HARWIN 1.7 mm Titanium Copper Alloy Surface Mount Grounding Contact S7121-42R

HARWIN S7121-42R is a 1.7 mm grounding contact composed of titanium copper alloy, with gold plating to ensure excellent electrical conductivity and corrosion resistance. The surface mount design is optimized for automated PCB assembly processes, making it ideal for high-volume manufacturing environments.

This grounding contact features a C-style spring configuration that provides reliable wiping and sliding action to maintain positive contact with metal shields or frames. It supports a continuous current rating of 4A, suitable for typical PCB grounding and shielding requirements.

Compact dimensions (1.7 mm height, 1.5 mm width, 2.7 mm length) make this product ideal for use in tight spaces or blindmate applications where access is limited. The robust spring properties ensure consistent contact pressure and durability.

These contacts are commonly used in electronic components prototyping, point-of-sale terminals, home entertainment systems, instrument panels, industrial process control equipment, motion control units, and mobile power devices. They are well-suited for applications requiring reliable grounding and EMI/RFI shielding.

Fabricated from titanium copper alloy for optimal strength and performance. Gold plating enhances conductivity and corrosion resistance. Surface mount fixing allows for automated placement on PCBs. Support for 4A current capacity.

Compact size fits into restricted application spaces. Reliable spring contact mechanism for wiping and sliding actions. Applicable across industrial, commercial, and laboratory electronics uses.
