Teledyne Relays MCR Metal Cover Shielded Reed Relays

Teledyne MCR Metal Cover Shielded Reed Relays provide both the consistency and reliability of a sealed reed switch with the convenience of an integrated coil inside a metal cover package. Rhodium switch contacts are hermetically sealed in glass, mounted on an integral lead frame, then sealed in a metal cover with magnetic shielding to minimize magnetic interference with other relays or other components on the PCB. The metal package with terminal pins allows these relays to be soldered directly into a PCB or inserted into sockets for convenient replacement. These MCR relays are available in multiple contact forms, with several coil voltages and with or without an internal suppression diode.
