American Zettler AZ420-1011-4W Industrial Relay

AZ420-1011-4W is a 12 V DC coil plug-in industrial relay from American Zettler, part of the AZ420 family, designed for general-purpose switching in control panels and automation equipment. The AZ420 family offers flexible contact configurations (SPDT, DPDT, 3PDT, 4PDT) and compatible sockets and mounting hardware for plug-in installation in compact control boards. The 12 VDC coil provides actuation for signaling and switching of medium loads, with coil power and exact ratings varying by configuration; consult the AZ420 selector guide for the precise combination of contact arrangement and ratings that matches AZ420-1011-4W. American Zettler lists the AZ420 series as End of Life, with the last order date set at October 31, 2019 and the last ship date targeted for end of Q1 2020; there is no direct drop-in replacement. Typical applications include machine controls, process equipment, and HVAC control circuits where reliable electromagnetic switching is required. For installation, ensure you obtain the appropriate socket or mounting accessory if your design requires plug-in installation with a panel or PCB, such as sockets designed for AZ420 relays.
