Product Description:

Danaher's EA170-31302 professional Snaplock Limit Switch series is resilient enough to withstand the demands of a manufacturing environment.

The limit switch's 600 V and 5.0 A rating, which operates within a power factor range of 75% to 100%, allows it to handle applications of any type. Types 1, 4, and 13 NEMA enclosures guarantee that the switch stays oil-proof and keep water and dust out of its housing. The housing material of EA170-31302 is engineered with zinc and aluminum zinc metals to defend against corrosion and ensure reliable operation over time. The switch offers a solid feel to the touch due to its regular shipping weight of 3.5 pounds and optional versions at 4 pounds, which show strong construction quality. There are several ways to modify the lever position of the EA170-31302 switch. The standard shaft may be adjusted in stages of 7degrees30' to 167degrees. Users may position the switch for 360-degree modifications to suit any mechanical arrangement demands thanks to the reverse shaft construction.

This design creates a robust and reliable switch connection system by using butt-shaped Form Z silver alloy contacts. A mounting plate with four holes is included with the equipment for simple and secure connection. All four holes have a uniform size of 0.255 to 0.260 inches. This device can run in temperatures between 0degrees C and 90degrees C while meeting crucial safety standards IEEE 323, 344, 383, which makes it suitable for applications with stringent safety demands, especially in nuclear settings. The EA170-31302 serves multiple installation styles including regular, wide, and long options, for safety and sensing operations. It can be purchased at Wake Industrial with a one-year warranty.
