ZIF Sockets
High current Zero Insertion Force (ZIF) test sockets populated with 50A rated contacts.
The Tooltronics Zero Insertion Force (ZIF) Test Socket allows devices to be inserted and removed without applying force, protecting delicate leads from stress and damage. The socket utilizes our HPK-FS Series flat serrated contacts to deliver reliable electrical performance and repeatable test results.
A cam and slide design engages the contacts once the device is in position, securely gripping the leads to provide a stable electrical connection during testing.
Optional device guides ensure proper device orientation during insertion, helping prevent misalignment, bent leads, and contact damage. This design makes the ZIF Test Socket well suited for laboratory, engineering, and production test environments.
