G5LE-1-DC5

Omron Electronics
General Purpose Relays SPDT 5VDC Flux Protected

Overview

The G5LE-1-DC5 is a subminiature SPDT (1 Form C) power relay from Omron, designed for reliable switching in a compact 22.5mm x 16.5mm footprint. It features a 5VDC coil sensitivity and is flux-protected, making it suitable for automated soldering processes on printed circuit boards. This relay is capable of switching loads up to 10A at 250VAC or 30VDC, balancing size and power handling.

Why Choose This Part

The G5LE series offers a high switching capacity of 10A in a small through-hole package, saving valuable PCB real estate. Its flux-protected construction prevents soldering flux from entering the housing, ensuring high contact reliability after assembly. Additionally, the 5VDC coil voltage is ideal for direct or transistor-buffered operation from common 5V logic rails.

Applications

Home Appliances
Commonly used in microwave ovens, washing machines, and HVAC controllers for switching heating elements and motors.
Industrial Controls
Acts as an interface between low-power PLC outputs and high-current actuators or solenoids.
Smart Lighting
Integrates into smart switches and IoT hubs to control lighting circuits remotely.
UPS and Power Supplies
Provides physical isolation and power path switching in uninterruptible power supplies and battery chargers.

Getting Started

When designing with this relay, ensure the driving transistor or logic gate can handle the coil current and always include a flyback diode (e.g., 1N4148) across the coil pins to prevent inductive spikes. Use wide PCB traces for the load pins to handle the rated 10A current and maintain proper creepage and clearance distances between the low-voltage coil and high-voltage load sections.
