Benefits

Flexible Mechanical Actuation

The spring-rod design provides flexibility when machine components approach the actuator from different directions.

Long Service Life

The actuator is designed for repeated mechanical operation in industrial machinery.

Modular Design

It forms part of the Siemens 3SE5 modular position-switch system, allowing compatible actuator heads and switch bodies to be selected according to the machine design.

Easy Replacement

The separate actuator-head design is useful when replacing a damaged or worn actuator while retaining a compatible 3SE51/52 position switch.

Important Compatibility

The 3SE50000AR01 is specifically intended for 3SE51/52 position switches with snap-action contacts.

It should not be selected for slow-action contact configurations.

Also, Siemens specifies that spring-rod actuators must not be used for safety circuits. Therefore, this actuator is intended for suitable position-monitoring and control applications rather than safety-related switching functions.
