Product Description:

The EA700-85000 limit switch is built by Danaher within the Snaplock Limit Switches series. Designed for automated lines, the unit converts a set lever rotation into an isolated electrical change, giving controllers a precise end-of-stroke signal that can halt motion, index tooling, or initiate safety interlocks. A sealed zinc housing and an internal contact mechanism allow the device to withstand repetitive cycling in material-handling, packaging, and assembly stations.

In its neutral position, all four contacts remain open, following the 4 N.O. contact arrangement wired in Form Z. These silver-alloy contacts close only when the shaft moves, and their low resistance supports control-level currents. Clockwise actuation requires 19.5 in-lb of torque, and the contacts trip after 11° of rotation, creating a quick snap to full conductivity that minimizes chatter. Once released, the lever springs back and resets at 9°, so the differential helps prevent false resets caused by vibration. A 7°30' lever adjustment range allows the cam profile to be aligned without repositioning the housing. Long mounting slots accept standard hardware and provide additional support on vibrating frames.

Counterclockwise movement is calibrated differently to accommodate bidirectional cams. The switch trips after 35° of rotation, requires only 15 in-lb of torque in the opposite direction, and resets at 13° of rotation. This movement creates an overtravel window that provides a full wipe across the contact faces. Danaher recommends 45° of working rotation, leaving space before the mechanical stop and reducing stress on the mechanism. Across both directions, the lever can move through a 90° total stroke without damage, and the contact format allows independent circuits to mirror each other or provide redundant feedback. Because every contact returns to an open state when the lever centers, operation can be checked with a continuity meter without removing the field wiring.
