Low Signal Relay
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 reduc-
es relay size, magnetic interference, and contact bounce
time.
• Single or dual coil winding types available.
Ordering Information
To Order: Select the part number and add the desired coil voltage rating, (e.g., G6A-274P-ST-US-DC12).
