Siemens Rotary lever for 3SE52 limit switch

Actuator type: Rotary lever
For use with: Limit switch 3SE5

The limit switch actuators 3SE5 are a series of switch heads designed for use with the SIRIUS limit switch series 3SE5. Due to their plug connection and standardized interface, these switch heads can be easily replaced. They are compatible with both modular switching units and complete switch units. Rounded plungers and roller plungers allow operation in the direction of the plunger axis or with the rod at a right angle to the plunger axis. Rounded plungers and roller plungers have an additional follow-up path, providing a greater operating distance. For lateral actuation and a relatively long follow-up path, the roller plunger is recommended.

Roller levers and angled roller levers offer different approach angles (α = 30°) and follow-up angles (γ = 45°), depending on the output direction (left or right). The actuating elements are made of finely ground steel in the form of cams, straight edges, or cam discs. Rotary levers and rod actuators are designed for high starting speeds (v = 1.5 m/s) and offer a variety of starting options. They are resistant to oil, grinding dust, ice, and coarse-grained materials.

With the rotary lever, the maximum approach angle is always equal to the maximum follow-up angle. Plunger actuators are available when no actuator with approach and follow-up angle is possible. A 10° adjustment of the rotary lever is possible. Spring rods can be used for undefined actuations and varying starting conditions, with the start occurring from any direction. Roller plungers are designed for central mounting with a thread of M18 x 1, allowing for quick installation and easy adjustment. Fork levers can be switched in two directions and provide a latching actuating element for alternating movements.
