Overview
The G5Q-14-1A power relay is a general-purpose electromagnetic relay manufactured by Omron. This product is sold as a 20-pack, ideal for single board computer projects, Arduino, and other electronics work. It is available in coil voltage options of 5V, 12V, and 24V, and can switch loads up to 10A. With a 5-pin SPDT configuration, it supports a wide range of control applications.
Key Features
Coil voltage options: DC5V, DC12V, or DC24V – choose the one that matches your project's power supply. Contact rating: 10A (resistive load) – capable of driving motors, lamps, and other medium-power loads directly. 5-pin layout (common, normally open, normally closed, coil+, coil-) for easy wiring. 20-pack bulk packaging – cost-effective for multi-relay systems or as spare parts. * Compact size (approx. 20mm x 10mm x 16mm) – fits breadboards and perfboards easily.
Connectivity & Compatibility
This relay is controlled via GPIO pins of single board computers (Raspberry Pi, Arduino, ESP32, etc.) using a transistor or relay driver module. The coil draws about 40mA at 5V, so a driver circuit is required for direct GPIO control. The contacts are rated for both AC and DC, up to 250VAC / 30VDC. Proper wiring of the 5 pins (2 coil pins, 3 contact pins) is essential.
Product Info
This product is continuously available on and other electronics retailers. The 20-pack price is approximately 1,000–1,500 JPY (tax included), offering excellent value. Warranty depends on the seller; it is sold as standard electronic components. No accessories are included – only 20 relay units.
Best Use Cases
Ideal for hobbyists and professionals working on single board computer automation projects (home automation, robot control, sensor integration). Perfect for those planning to build multi-relay systems (e.g., custom 8-channel relay boards) – buying in bulk saves money. * Great as a stock of spare parts or for educational purposes to learn relay operation.
