Finder 40.52.9.005.0000 Miniature Relay, 2-Pole, 8A, 5V DC

The Finder 40.52.9.005.0000 is a high-performance miniature relay engineered for precise switching in diverse electronic and industrial control environments. This 2-pole double-throw component is designed to provide reliable operation within compact systems, offering a robust solution for managing electrical circuits where space is at a premium. With its 5V DC coil and 8A contact capacity, it serves as a dependable interface between low-voltage control signals and higher-load power circuits.

Advantages

This miniature relay stands out due to its compact footprint, which allows for high-density component placement on printed circuit boards without sacrificing switching power. The construction ensures long-term durability and consistent performance under standard operating conditions. Its design minimizes power consumption while maintaining high contact reliability, making it an efficient choice for modern automation and control hardware.

Suitable for

• Industrial automation systems
• Printed circuit board (PCB) assembly
• General electrical control circuits
• Signal switching in electronic devices

When it may not be suitable

This relay is not intended for high-voltage power distribution or applications requiring switching currents significantly exceeding 8A. It is also not suitable for environments with extreme moisture, dust, or corrosive gases unless housed in a protective enclosure.

Key specifications

• Contact configuration: 2-pole (DPDT)
• Rated current: 8A
• Coil voltage: 5V DC
• Mounting type: PCB mount

How to use

To integrate the relay, solder the pins directly onto the designated PCB footprint. Ensure that the coil voltage matches the 5V DC supply provided by your control circuit to prevent coil damage. Connect the load to the appropriate contact terminals based on the desired normally open or normally closed state. Always verify that the current and voltage ratings of your load do not exceed the relay's specified limits before applying power.

What to consider before purchase

• Verify the coil voltage matches your control system output
• Ensure the PCB layout accommodates the pin configuration
• Check that the 8A contact rating is sufficient for your specific load

Usage recommendations

For optimal longevity, ensure the relay is operated within its specified electrical ratings and avoid exceeding the maximum switching frequency. Proper thermal management on the PCB is recommended to maintain stable performance.
