High speed spring contact adapter can be design in different ways. It is better to choose first the right spring contact design: Requested frequency per contact. Single or double ended. With or without flange. Minimum height & travel. With or without barrel (open). Plunger shape & other specifications. ADR also offer the “S-Parameters” information for most the spring contacts (Db/Frequency graph).

Standard spring contacts can be used for 6Ghz frequency maximum. For higher frequencies, a special contacts and contacts arrangement are required. These spring probes can transfer the signals between PCB’s or other layers. ADR offers a wide range of spring contacts for high speed data transferring. There are both single and double action probes.

”Barreless” spring contacts were developed to reduce the spring-contact cost and to improve the signals transfer. These kind of contacts required appropriate socket. Short pins enable higher speed performance. ADR offers short “barreless” spring contacts in length of 3-4mm. The contact is made of one or three parts only. The one-piece spring contact is a low cost solution because it doesn’t require assembly process during production.
