The Relpol RM85-2021-35-1012 is a high-performance miniature electromagnetic relay engineered for precise switching in industrial and electronic control environments. This component is designed for direct PCB mounting, providing a reliable interface between low-voltage control signals and higher-power electrical loads. With its 12V DC coil and 2CO contact configuration, it serves as a versatile solution for managing complex electrical circuits in automation and power management systems.
Advantages
This relay offers exceptional reliability and durability, ensuring consistent performance even in demanding operational conditions. Its compact design allows for efficient space utilization on printed circuit boards, making it an ideal choice for modern electronic assemblies where footprint is a critical factor. The high contact rating of 16A enables the switching of significant electrical loads, while the 2CO configuration provides flexibility for dual-circuit control within a single, space-saving package.
Suitable for
- Industrial automation and control systems
- Power management and distribution circuits
- Electronic equipment and appliance control
- Signal switching in low-voltage applications
- General-purpose electrical circuit integration
When it may not be suitable
This relay is not intended for high-frequency switching applications that exceed its mechanical and electrical life ratings. It is also not suitable for environments with extreme moisture, corrosive gases, or excessive vibration unless housed within a protective enclosure designed for such conditions.
Key specifications
- Coil voltage: 12V DC
- Contact configuration: 2CO (DPDT)
- Maximum contact current: 16A
- Mounting type: PCB
- Compact miniature design
How to use
To integrate the relay into your circuit, ensure the PCB layout matches the pin configuration of the component. Solder the relay pins carefully to the board, ensuring that the soldering temperature and duration do not exceed the manufacturer's thermal limits to prevent internal damage. Connect the 12V DC control signal to the coil terminals and wire your load circuits to the appropriate common, normally open, and normally closed contacts according to your schematic requirements.
What to consider before purchase
- Verify that your control circuit provides a stable 12V DC supply.
- Ensure the load current does not exceed the 16A rating.
- Check the physical dimensions against your PCB space availability.
- Confirm the contact configuration meets your specific switching logic.
Usage recommendations
Always ensure that the power supply is disconnected before installing or replacing the relay. Regularly inspect the solder joints and contact connections to maintain optimal performance and prevent overheating in high-load applications.
