T-Bar Hermetically Sealed Relays

881/981 Relays
887/987 Magnetic Latching Relays

T-Bar Hermetically Sealed Multipole Relays offer contact protection against corrosive atmospheres, splashing water, sand, dust, salt spray and altitude changes. Switching and operating specifications and reliability are identical in all T-Bar Relays because the same switching wafers and actuators are used.
Standard T-Bar Relays are installed in hermetically sealed metal enclosures, using glass-to-metal sealed connectors. The enclosure is backfilled with an inert gas to protect the relay for shipboard, ground support and selected airborne applications. The glass sealed termination mates with MS connectors. Pulse operated magnetic latching relays are available. Standard switching configurations are: 24C, 36A, 48A, 34C, 51C.
