199AX-4 DAYTON Vac Coil Spdt Power Relay Terminal Mount

Review DAYTON 40a 120 Vac Coil Spdt Open Power Relay Terminal Surface Mount

The Dayton 199AX-4 is a 40A, 120V AC single-pole double-throw (SPDT) power relay designed for terminal mounting applications. This reliable and versatile component is essential for various control systems, automation projects, and industrial applications.

The 199AX-4 coil is engineered with a 40A current handling capacity and operates on a 120V AC voltage. It's designed as a SPDT relay, meaning it has three terminals: Common (COM), Normally Open NO1, and Normally Open NO2. When no coil voltage is applied, the contacts are in their normal position, keeping NO1 and NO2 separated. However, when the coil is energized, the contacts switch, connecting COM to NO1 and disconnecting it from NO2.

This Dayton power relay features a rugged construction, ensuring its durability even in harsh environments. The terminal mount design allows for easy installation, as it can be directly mounted on a PCB or panel. The relay is also RoHS compliant, making it an environmentally friendly option for your projects.
