SMD/EMI spring contacts handle electrical conduction, grounding, and elastic contact on PCBs — small components that carry outsized reliability requirements in electronics, communications, and automotive systems. Here's how our contact types differ.
TYPE C
Our standard C-type SMD spring contact is built for general PCB grounding and conduction, available in multiple heights and current ratings to fit a range of board designs.
TYPE 3 & S
Three-prong (Type 3) and S-profile contacts are engineered for higher retention force and improved contact reliability in more demanding environments — where vibration or repeated connection cycles put more stress on the contact point.
OTHER TYPES
Beyond our standard offerings, we engineer custom and specialty contact geometries to match specific customer requirements, all available in tape-and-reel packaging for automated SMT assembly.
APPLICATIONS
- Consumer electronics. PCB grounding and board-to-board conduction in compact devices.
- Communications infrastructure. Reliable EMI shielding and grounding in networking and telecom equipment.
- Automotive electronics. Contacts engineered to maintain reliability under vibration and thermal cycling in vehicle environments.
WHY THIS MATTERS
Choosing the wrong contact type usually shows up as an intermittent connection issue in the field — hard to diagnose and expensive to trace. Tell us your board design and operating environment, and we'll recommend the contact type built for it.
Send us your drawings, samples, or requirements and our engineering team — backed by 20+ years of spring and machinery manufacturing experience — will get back to you with a competitive quote and realistic turnaround.
