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

Note: 1.
The contact resistance was measured with 10 mA at 1 VDC with a fall-of-potential method.
2.
Values in parentheses are typical values unless otherwise stated.
3.
The insulation resistance was measured with a 500-VDC megohmmeter applied to the same parts as those for checking the dielectric strength
(except between the set and reset coil).
4.
The above values are initial values.
