Product Description:
Danaher's EA170-14300 Limit switch is a rotary-operated device that provides accurate electrical control for detecting rotary motion. The switch is widely used in industrial automation systems and is designed specifically for tasks that require dependable cam-actuated switching.
The EA170-14300 limit switch can handle two voltage ratings: 125V at 20A AC and 5A DC. Other ratings are 250V at 15A AC/1.5A DC, 480V at 10A AC, and 600V at 5A AC. The switch's serrated rotating shaft provides a stable mounting for cams or levers. The top plate of the lid is composed of stainless steel, which shows its durability. The switch is most likely made of die-cast zinc. The shaft allows for continuous or cyclic rotation, as well as for maintaining or short journey activation. Two contacts are generally open and two contacts are normally closed in Form Z, forming a DPDT configuration for the contact block. The right-hand channel entry features a blue insert compatible with the EA170 series' 302 connection option. The bolt and shaft alignment indicates that the mounting configuration is more likely the front shaft, with conventional or wide mounting choices. The standards set by NEMA 1, 4, and 13 are satisfied by the switch.
The EA170-14300 Limit switch operates within a temperature range of 0 to 90 degrees Celsius and may resist brief exposures to temperatures as high as 175 degrees Celsius. The limit switch weighs about 3.5 pounds. Over its entire 173-degree range, the lever can be turned in increments of 7°30′. The EA170 switch offers constant mechanical performance and reliable switching action. The switch is built to be included in systems that necessitate accurate mechanical input tracking and repeatable actuation. The limit switch is used in panel and actuator assemblies for automated manufacturing processes.
