Low Signal Rela y G6A
■ High sensitivity – can be driven by digital
circuits
■ Low-profile design allows use in 12.70 mm
(0.50 in) PC board rack
■ Surge withstand voltage meets FCC Part 68
regulation
■ Units can be mounted side by side due to
low magnetic leakage
■ Special models available for ultrasonic
cleaning and low thermoelectromotive force
■ Unique moving loop (permanent magnet)
armature reduces relay size, magnetic
interference, and contact bounce time
■ Single or double coil winding types available
