Low Signal Relay
G5A
• Subminiature 8.40 H x 9.90 W x 16 L mm
(0.33 H x 0.38 W x 0.63 L in).
• Unique moving magnet armature reduces relay size,
magnetic interference, and contact bounce time.
• Low nominal power consumption (200 mW).
• Bifurcated crossbar contact assures highly reliable
switching of loads as low as 10 mVDC, 0.1 mA
(reference value).
• Automatic flow or dip soldering possible.
• Available in standard, high-sensitivity, high-dielectric
(FCC part 68), low thermoelectromotive force, and
ultrasonic cleaning versions.
• Highly stable magnetic circuit for latching endurance and
excellent resistance to vibration and shock.
• Single or double coil winding types available.
Ordering Information
To Order: Select the part number and add the desired coil voltage rating (e.g., G5AU-234P-DC12).
