Relay G5V-2-H1, 5V DC/125V AC 2A

Omron G5V-2-H1 is a miniature signal relay for PCB mounting with a 5 V DC coil in the High-sensitivity version. Thanks to the DPDT (2c) contacts, it is suitable for switching two independent circuits in control, measurement and communication applications where low coil power consumption is required.

Installation and operating instructions

• Observe the nominal coil voltage of 5 V DC and the correct polarity according to the wiring of your board.
• For switching inductive loads, use appropriate surge suppression (e.g. diode for DC, RC element/varistor for AC)
• Respect the nominal values for resistive loads and verify suitability for the specific switched load under real-world conditions.

Safety notice

• There is a risk of electric shock when switching 125 VAC/125 VDC and higher currents; installation should only be performed by a qualified person
• Ensure sufficient insulation distances on the PCB and follow safe design principles for working with hazardous voltages
