A range of actuator heads for use with the SIRIUS 3SE5 series limit switch. The actuator heads can be easily replaced thanks to their plug mounted design and uniform interface. Compatible with both the modular switch units and the complete switch units.

Operation in direction of the plunger axis or with bar at right angles to the plunger axis
Rounded plungers and roller plungers have an additional overtravel and hence a larger operating distance
The roller plunger is recommended for lateral actuation and relatively long overtravel

Depending on the direction of starting (left or right), various approach angles (α = 30°) and trailing angles (γ = 45°) are possible
For actuators made of finely ground steel in the form of cams, straight-edges or cam disks

For a high starting speed (v = 1.5 m/s)
Variety of starting options
Insensitive to oil, grinding dust, ice and coarse-grained material
With the twist lever the maximum approach angle is always equal to the maximum trailing angle
Rod actuator - when no actuator with approach and trailing angle is possible
10° adjustment of the twist lever possible

Can be used for undefined actuations and changing starting conditions
Starting from any direction

Fast assembly
Easy adjustment

Switchable in two directions
Latching actuator
For reciprocating movements
