Package contents

• OMRON G5V-2 relay, 5 V DC coil

Why choose this product?

• Proven DPDT (2 Form C) design for universal use in signal and control circuits
• Clearly defined switching and insulation parameters for the design of reliable devices
• Standard version suitable for common applications with 5 V DC coil

Installation and operating instructions

• When designing a printed circuit board, observe the recommended insulation distances and track widths according to the switching voltage and current.
• To achieve the declared service life, use the relay within the rated values for the given load type (resistive/inductive)
• For inductive loads, consider using appropriate suppression (e.g. RC element, diode, varistor) depending on the type of power supply and load.

Safety notice

• The relay is capable of switching voltages up to 125 VAC / 125 VDC; when working with hazardous voltages, ensure adequate shielding, protection and compliance with safety standards
• Only perform installation and service when the power supply is disconnected.
