Finder 34.51.7.024.0010 Miniature PCB Relay, 24V DC, 6A, 1 CO Contact

The Finder 34.51.7.024.0010 is a high-performance miniature PCB relay engineered for precise switching in electronic control systems. With a slim profile of only 5 mm, this relay is specifically designed for high-density circuit board layouts where space is at a premium. It operates on a 24V DC coil voltage and provides reliable signal switching for various industrial and automation tasks.

Advantages

The primary advantage of this relay is its extremely compact design, which allows for significant space savings on printed circuit boards. It features a robust construction that ensures reliable operation across a wide temperature range from -40 to +85 degrees Celsius. The use of high-quality AgNi contact material guarantees durability and consistent electrical performance. Furthermore, it provides secure electrical isolation, meeting stringent safety standards for industrial equipment.

Suitable for

• Industrial automation control systems
• Electronic interface modules
• Space-constrained PCB designs
• Signal switching in control panels
• Home automation and smart building controllers

When it may not be suitable

This relay is not intended for switching high-power inductive loads that exceed its 6A current rating or 1500 VA switching capacity. It is also not suitable for applications requiring direct AC coil control, as it is designed specifically for 24V DC operation.

Key specifications

• Coil voltage: 24V DC
• Contact configuration: 1 changeover (CO) contact
• Maximum switching current: 6A
• Maximum switching voltage: 400V AC
• Dimensions: 5 mm width, 15 mm height, 28 mm length
• Contact material: AgNi
• Operating temperature range: -40 to +85 °C

How to use

The relay is designed for direct mounting onto printed circuit boards using its integrated solder pins. Ensure that the PCB layout matches the pin configuration of the device. When soldering, use standard electronic assembly practices to avoid overheating the pins, which could damage the internal coil or contact mechanism. Once installed, connect the 24V DC control signal to the coil terminals and wire the load circuit through the changeover contact pins according to your schematic requirements.

What to consider before purchase

• Verify that your control circuit provides a stable 24V DC supply.
• Ensure the load current does not exceed the 6A limit.
• Check the physical dimensions to confirm it fits your PCB layout.
• Confirm that the environment does not exceed the specified temperature limits.

Usage recommendations

For optimal longevity and performance, ensure the relay is protected from excessive vibration and moisture. When switching inductive loads, it is recommended to use an external flyback diode or snubber circuit to protect the relay contacts from voltage spikes.
