PCB Relay G6A
Plastic-sealed 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 thermoelectromo
-
tive force.
