Spring Contacts
Spring Loaded Contacts and Contact Pads
By using either spring forces inherent in bent metal, or an encapsulated miniature spring, these contacts can provide a single contact point for connection, without any specific style of mating connector required. Just a plain conductive surface is required, either to conduct signal current, or for grounding purposes.
SMT Spring Contacts
A comprehensive range of single piece spring contacts, suitable for shielding, grounding, mobile phone antenna and other general electrical connection applications. Also known as antenna contacts, grounding contacts or shield fingers.
- Development Kit DEV-001 with 16 different contacts and free refills
- 30 different designs, ranging from 1.23mm to 7.25mm vertical free heights
- Option of horizontal spring contacts for 90 degree connection
- Protected tip options to prevent hooking
- Positive stop options, to prevent over-stressed contacts
- 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
- All contacts are Surface Mount, supplied in Tape and Reel packaging for automated assembly placement
Spring Loaded SMT Contacts – Pogo Pins
Spring loaded contacts consist of a plunger (or head), barrel (or body), and a fully encapsulated fine spring, to provide the spring force required to maintain positive contact. All have a high durability, exceeding 10,000 mating cycles.
- Surface mountable vertical spring loaded contact pins, free height from 2.8mm to 8.2mm
- Option of Throughboard peg – can be used for Plated-Through-Hole soldering, or just as a SMT location peg
- Rounded contact heads with Gold finish for minimal wear
- Some options supplied in Tape and Reel packaging for automated assembly systems
ATE Test Probes
Probes ideal for automated test equipment (ATE), mounted in a “bed of nails” layout. Consists of a plunger (or head), barrel (or body), and a fully encapsulated fine spring, to provide the spring force required to maintain positive contact. All have exceptional durability to cope with multiple testing cycles.
- Throughboard design for glue or solder application
- Single piece, or two-piece probe and sleeve – probe can be replaced at end of life without de-soldering
- A variety of head style choices, for contact through contamination or leaving no contact marking
- Durability exceeds 100,000 mating cycles
- Choice of end terminations for wire-wrap, crimp or solder to test leads
SMT Contact Pads
Multi-purpose flat contact pads for Surface Mount fixing – thicknesses between 0.1mm and 0.5mm. Ideal for providing a more robust surface than direct track contact.
- Supplied in Tape and Reel packaging for automated assembly systems
- Gold finish for maximum wear resistance
- Choice of contact pad shapes – square, round or oval
