G6A PCB Relay
Fully Sea led Relay with High Impulse
Dielectric for Use in
Telecommunications Equipment
■High sensitivity can be driven by digital circuits.
■Horizontal design allows use in 1/2-inch PCB
racks.
■Impulse withstand voltage meets FCC Part 68
requirements.
■Relays can be mounted side-by-side due to low
magnetic leakage.
■Single- and double-winding latching relays also
available.
■Special models available for low thermoelectro-
motive force.
