Siemens 3SE5 Series Limit Switch Operating Head for Use with 3SE5 Limit Switch

3SE5 Limit Switch Actuators

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.

Rounded plungers and roller plungers

• 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

Roller levers and angular roller levers

• 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

Twist levers and rod actuators

• 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

Spring rods

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

Roller plungers for central fixing with M18 x 1 thread

• Fast assembly
• Easy adjustment

Fork levers

• Switchable in two directions
• Latching actuator
• For reciprocating movements
