Phoenix Contact 2961105 Power Relay, 24V DC, 1-Pole

The Phoenix Contact 2961105 is a high-performance miniature power relay engineered for reliable switching in demanding industrial electrical control systems. Operating with a 24V DC coil, this 1-pole relay features a single-pole double-throw (SPDT) contact configuration, making it an essential component for signal isolation and power management in automated environments. Its compact design and robust construction ensure consistent performance, providing a dependable solution for circuit control and protection within control cabinets and industrial machinery.

Advantages

This relay offers significant benefits due to its space-saving 5 mm width, which allows for high-density mounting in confined spaces. The use of high-quality silver tin oxide contact material ensures excellent electrical conductivity and durability, even under frequent switching cycles. Its versatile design supports a wide range of switching voltages up to 250V AC/DC, providing flexibility for various control applications. The pluggable miniature form factor simplifies installation and maintenance processes, reducing downtime in industrial operations.

Suitable for

• Industrial automation and control systems
• Control cabinet assembly
• Signal isolation between control and load circuits
• Switching small to medium power loads in machinery

This relay may not be suitable for applications requiring high-current switching beyond the 6A limit or for environments exposed to extreme vibrations or corrosive atmospheres without additional protective housing. It is not intended for direct high-voltage power distribution or applications where a multi-pole switching configuration is required.

The relay is designed for mounting via solder pins, typically onto a compatible printed circuit board or a specialized relay socket. Ensure the control circuit provides a stable 24V DC supply to the coil terminals to guarantee proper switching operation. When integrating into a circuit, verify that the load current and voltage do not exceed the specified maximum ratings to prevent contact welding or premature failure.

What to consider before purchase

• Verify the coil voltage matches your control system output
• Ensure the physical dimensions fit your PCB layout or socket space
• Check that the maximum load current of your application is within the 6A limit
• Confirm the mounting method is compatible with your existing hardware

For optimal longevity and performance, ensure the relay is kept within its specified operating temperature range and protected from moisture or dust. Regularly inspect the solder connections for signs of thermal stress or oxidation in high-duty cycle applications.
