Harwin, a manufacturer of electrical and electronic interconnect solutions, has expanded its range of EZ-Spring Contacts with new contact styles and heights. Part of the EZ-BoardWare range of PCB hardware products, the surface mount spring contacts—also known as spring fingers or grounding contacts—are now available in 15 different sizes, ranging from 1.70mm to 7.25mm free height (1.20mm to 6.35mm minimum working height). The new spring contacts are suitable for both vertical and horizontal contact actions.
EZ-Spring Contacts are used as grounding or shielding contacts in contact with metal frames or shields, or for general electrical connection between PCBs, the company said. Mounted in a row, the contacts can provide an excellent RFI shielding connection for metal doors or other cabinet enclosures. The contact design ensures positive contact with the mating surface, and is tolerant to both wiping and sliding action.
“These EZ-Spring Contacts are ideally suited for automated applications requirements including motion control units, mobile power units, environmental monitoring systems and broadcast, comms and industrial process control equipment,” product manager Paul Gillam said.
Individual clips are supplied in tape and reel packaging for automated placement, and reduce manufacturing costs by eliminating time-consuming secondary assembly operations. AProtected tip design prevents the product from hooking.
