Finder 67.23.9.024.4300 Power Relay, 24 V DC, 50 A, 3 NO Contacts

The Finder 67.23.9.024.4300 is a high-performance power relay engineered for demanding industrial environments and heavy-duty electrical switching. Designed specifically for integration into printed circuit boards, this monostable relay features a 24 V DC coil and is capable of handling significant electrical loads with a maximum switching current of 50 A. Its robust design and high-quality contact material ensure reliable operation in complex power distribution and automation systems.

Advantages

This power relay offers exceptional switching capacity, supporting up to 20000 VA, which makes it suitable for high-power applications. The use of AgSnO2 contact material provides excellent resistance to welding and wear, extending the service life of the component even under frequent switching cycles. Its compact dimensions allow for efficient space utilization on circuit boards, while the 3 mm contact gap ensures safety and reliability in demanding industrial settings.

Suitable for

• Industrial inverters
• Power distribution systems
• Automation and control panels
• Heavy-duty electrical switching applications

When it may not be suitable

This relay is not intended for low-voltage signal switching or applications requiring high-frequency switching beyond its mechanical and electrical ratings. It is also not suitable for environments where the ambient conditions exceed the specified temperature or humidity limits for electronic components.

Key specifications

• Coil voltage: 24 V DC
• Switching current: 50 A
• Contact configuration: 3 normally open (NO) contacts
• Maximum switching voltage: 690 V AC
• Maximum switching power: 20000 VA
• Coil resistance: 340 Ohm
• Dimensions: 51.5 x 33 x 57.5 mm
• Connection type: Solder pins

How to use

The relay is designed for direct mounting onto printed circuit boards using the integrated solder pins. Ensure that the PCB layout is capable of handling the high current loads associated with 50 A switching. The coil should be energized with a stable 24 V DC supply, maintaining the voltage within the specified operating range of 21.6 V to 26.4 V DC to ensure reliable contact closure.

What to consider before purchase

• Verify that your PCB traces are rated for 50 A current.
• Ensure the 24 V DC power supply is stable and filtered.
• Check that the physical dimensions fit your enclosure or board layout.
• Confirm that the load type is compatible with the AgSnO2 contact material.

Usage recommendations

Always ensure that the power supply is disconnected before installing or replacing the relay. It is recommended to use appropriate heat management if the relay is operated at its maximum switching capacity for extended periods.
