TE Connectivity DRI Relays

TE Connectivity's (TE) DRI Relays are electromechanical hermetically sealed relays and sockets for applications that require dependability and long life. A balanced force design provides the benefits of consistently high contact pressure, reduced bounce, and less arching, leading to extended contact life. DRI Relays effectively support activities in the aerospace, military, rail, and space markets. The TE DRI Relay portfolio includes products qualified to stringent military specifications, including MIL-PRF-83536.
