887/987 Magnetic Latching Hermetically Sealed Series

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.

* Available in 12, 24 & 34 poles Form C
double throw.

* Coils may be operated from 6, 12, 24, 28,
48 and 110 Volts DC and 115 Volts AC.

* Protects against corrosive atmospheres,
water, sand, dust, salt and altitude changes.

* Uses glass-to-metal sealed connectors.
