Product Description:

Danaher's EA790-10100 Limit switch is made for precise operation in control applications that are very demanding. The switch is activated by a lever, which guarantees a consistent and dependable mechanical reaction. The EA limit switch is protected by enclosure grades NEMA 1, 4, 4X, 6, 6P, and 13, ensuring that it can operate in a variety of sealed environments.

The EA790-10100 limit switch works in temperatures ranging from -20°C to +90°C and keeps working well even when temperatures change. With a travel of 18 degrees, the switch allows you to decide how it responds when it is activated. The switch gives off 15 inch-pounds of torque, which makes sure that there is mechanical input and constant resistance. The mounting configuration is a front shaft for installations that need a straight front engagement. The switch doesn't have any wire leads, which makes unique electrical interfacing easier. When it comes to normal industrial control protocols, it can work with LS N/M CW/CCW R-F MIL-C-2212F NSP80. The sealing on the enclosure fits with the needs of industrial machinery, which needs to keep out outside elements and work reliably. The EA790 switch can be used in situations where repeatability, longevity, and mechanical accuracy are very important.

The EA790-10100 limit switch has a spot on the front shaft that allows for direct mechanical linkage. The values are 20 A at 125V AC, 15 A at 250V AC, 10 A at 480V AC, and 5 A at 600V AC. The limit switch can take 5 A at 125V and 1.5 A at 250V for DC use, making it compatible with both AC and DC systems. The EA790 switch is designed to meet very high standards for operating repeatability and torque needs. The switch gives clear movement under electrical loads while staying in line with mechanical and housing requirements.
