Low Signal Relay
G6A
Fullly Sealed Relay with High Impulse Withstand
• High sensitivity — can be driven by digital circuits.
• Low-profile design allows use in 12.70 mm 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 low thermoelectromotive force.
• Unique moving loop (permanent magnet) armature reduces
relay size, magnetic interference, and contact bounce time.
• Single or dual coil winding types available.
• RoHS Compliant
