The component is usually UL and cUL recognized, and often VDE approved.
You cannot drive this relay directly from a microcontroller (like an Arduino or PIC) because the coil requires more current than a logic pin can supply, and the coil voltage (12V) is higher than logic voltage (3.3V/5V).
Required Components:
Basic Wiring Steps:
The Omron G8B-201-01 is more than just a switch; it is a robust, engineered solution for high-reliability automotive and industrial applications. Its ability to handle 20 amps continuously, survive extreme temperatures from -40°C to +85°C, and resist vibration makes it a cornerstone component in engine control units, body control modules, and aftermarket power systems.
When designing or repairing a circuit that requires a 12V, 20A SPST-NO relay, the G8B-201-01 from Omron should be your first choice. Always respect its pinout, protect the coil with a flyback diode, and ensure the PCB traces are thick enough to handle the current. By understanding this component’s capabilities and limitations, you ensure a safer, longer-lasting electrical system.
Final Pro Tip: Keep a few of these relays in your workshop. They are ideal for custom automotive wiring projects where you need to switch a high-power device directly from a microcontroller or a low-current switch. Pair them with an inline fuse, and you have a professional-grade power control solution.
Disclaimer: Specifications and data are based on Omron’s official documentation. Always consult the latest datasheet before finalizing a design.
The part number "Omron G8B-201-01" refers to a specific automotive relay manufactured by Omron.
Here is the detailed article / datasheet summary for that component:
The Omron G8B-201-01 is a single-pole, single-throw (SPST) automotive relay, commonly referred to as a "1 Form A" relay. Its primary function is to act as a remote-controlled switch, using a low-current signal to control a high-current circuit. The "G8B" series is Omron’s answer to high-capacity PCB (Printed Circuit Board) mounting requirements in harsh environments.
The component is usually UL and cUL recognized, and often VDE approved.
