Product Description:

Danaher EA990-00085 Limit switch offers precise position detection and activation. The rocker-type mechanism ensures mechanical dependability and a long service life. The switch is designed to fulfill the needs of rotary-style switching components in industrial automation systems, where consistency and durability are paramount.

The EA990-00085 limit switch has 1 x open and 1 x closed contact when used in a Form Z setup along with butt contacts. Zinc with a gray painted finish makes up the housing. Dust, oil, and water are unable to penetrate the container that has been sealed. The exposed rotating operating shaft enables the lever to be adjusted in increments of 7.5 degrees across the entire vertical range of 360 degrees. Various panel layouts can be accommodated by the mounting options, which include broad and long mount possibilities. Ten amperes at 480 volts, twenty-five amperes at 600 volts, and fifteen amperes at 125 volts are the electrical ratings. The ratings for DC loads are 1.5 A at 250 V and 5 A at 125 V. In resistive and motor control circuits, the EA990 limit switch is suitable for power factor loads ranging from 75% to 100%.

The ideal temperature requirement of the EA990-00085 limit switch is between -20°C to +90°C. The switch weighs around 3.7 pounds. The switch is designed to withstand environments where it may be exposed to dust or oil. Industrial automation systems that use rotary-style actuators and levers with flexible positioning are suitable for the limit switch. When it comes to electrical control systems, the limit switch consistently delivers. You can order this EA990-00085 limit switch from Wake Industrial. It comes with a 1-year replacement warranty.
