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 reduces 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).
