807/907 Magnetic Latching Dust-Tight Series

T-Bar Multi-Contact Magnetic Latching Relays, pulse operated and magnetically bi-stable, add the advantages of eliminating power waste during long periods in an operated position, and maintainenance of circuit integrity during a power loss.

T-Bar Magnetic Latching Relays are the same physical size as T-Bar relays which require continuous power and are available in the same contact configurations.

All Switching and reliability specifications are identical.

Two control configurations are available. "Polarity inversion" control
is standard. The relay is driven into the set or rest (latch or unlatch) position by inverting the polarity of the control voltage. As an option, two coil, "Bifilar," operation can be supplied to latch or unlatch using the same polarity DC control voltage.
