Phoenix Contact PCB Power Relay 24V DC Coil 10mA SPDT REL-MR-24DC/21/MS 2909642

Phoenix Contact 2909642 is a compact PCB power relay specifically designed to provide reliable switching performance for low-voltage applications. The relay operates with a 24V DC coil and offers a switching current of up to 10mA. Its SPDT (Single Pole Double Throw) contact arrangement allows users to switch between two circuit states, offering flexibility in control applications such as programmable logic controllers, signal processing, and automation setups.

The device is engineered for secure PCB mounting, featuring five integrated pins that ensure a robust and stable installation. Its slim construction, with a height of 28mm, a length of 16mm, and a width of just 5mm, enables multiple relays to be densely packed on a board without requiring extra spacing. This makes it ideal for compact electronic designs where space optimization is essential.

Electrical conductivity is assured by its silver alloy contact material, which minimizes resistance and maximizes transfer efficiency. The relay supports both manual and automatic switching modes, thanks to its non-latching action, reverting to auto operation whenever power is disconnected.

The 2909642 model is suitable for a broad range of industrial and commercial applications. It is commonly used in audiovisual equipment, medical devices, communication systems, and automation circuits. With robust insulation and a wide operating temperature range from -40°C to 85°C, it remains dependable in harsh environments.

Electrical ratings are impressive: it can handle up to 250V AC or DC for switching, and its coil power is 0.17W, with a coil resistance of 3.4 kΩ. The relay offers a maximum switching power of 1.5 kVA. Installation is straightforward, and the relay’s lightweight design (approximately 4.7 g) ensures it minimally impacts overall assembly mass.

Additional product highlights include compliance with RoHS standards and compatibility with the REL-MR industrial relay series. Applications span industrial automation, signal switching in control panels, and reliable interfacing with electronic systems in manufacturing, research labs, and equipment construction.

For engineers seeking a miniature yet powerful relay solution, this Phoenix Contact relay is a top choice for efficiency and longevity in demanding conditions.
