K2-42V-3 Medium Power DPDT Plug-In Relay 42VDC 1A

The K2-42V-3 Medium Power Relay is a reliable plug-in relay engineered for precision control, signal switching, and industrial automation applications. Designed with a Form 2C (DPDT - Double Pole Double Throw) contact arrangement, this relay provides flexible switching of two independent circuits, making it ideal for control panels, instrumentation systems, telecommunications equipment, and industrial machinery.

Operating from a 42VDC coil supply, the relay delivers dependable switching performance while maintaining low power consumption of only 333mW. The 7.3k coil resistance ensures efficient operation and stable actuation, making it suitable for continuous-duty and long-term applications.

A key feature of the K2-42V-3 is its bifurcated silver contacts, which provide enhanced switching reliability, especially in low-level signal applications. The bifurcated design creates multiple contact points, reducing contact resistance and improving performance in sensitive control and monitoring circuits.

The relay is housed in a compact vertical package measuring 24 x 19 x 30mm and features a convenient plug-in mounting design. This allows for quick installation, easy replacement, and simplified maintenance, making it ideal for use with relay sockets in industrial and commercial environments.

With UL and CSA approvals, the K2-42V-3 meets recognised safety and quality standards, ensuring dependable operation in demanding applications. Its durable construction, reliable performance, and versatile switching capabilities make it a valuable component for engineers, technicians, and system integrators.
