The Siemens 3SE50000AF02 is a SIRIUS actuator head for 3SE51/52 position switches, featuring an angular roller lever with a metal lever and 22 mm stainless steel roller. It is designed for industrial position detection and mechanical limit-switch applications where a durable roller interface is required between the moving machine component and the position switch.
The actuator head is part of the modular Siemens SIRIUS 3SE5 position-switch system, making it suitable for OEM machinery, machine tools, conveyors, packaging equipment, production lines, and other industrial automation applications.
The 3SE50000AF02 is used to mechanically actuate a compatible 3SE51/52 position switch when a machine component reaches or passes the actuator.
The 22 mm stainless steel roller provides a rolling contact surface between the moving machine component and the actuator. This makes the configuration particularly suitable for applications where the machine movement occurs across the actuator rather than directly toward a fixed plunger.
Typical applications include:
The 3SE50000AF02 uses an angular roller lever arrangement.
The actuator consists of a metal lever carrying a 22 mm stainless steel roller. When the moving machine component contacts the roller, the lever moves and transfers this mechanical movement to the compatible position switch.
The angular configuration provides flexibility when the position switch cannot be installed directly in line with the moving component.
This can be useful when designing around:
One of the main features of the 3SE50000AF02 is its 22 mm stainless steel roller.
Compared with smaller plastic rollers, a stainless steel roller can be advantageous where a more robust rolling contact surface is required for industrial mechanical actuation.
The roller allows the moving machine component to pass over the actuator with rolling contact rather than directly sliding against the metal lever.
This configuration is particularly suitable for machinery where the actuator is subjected to repeated mechanical movement.
The actuator incorporates a metal lever, providing the mechanical connection between the stainless steel roller and the position-switch mechanism.
The metal lever is designed for repeated mechanical operation in appropriate industrial applications.
For reliable operation, the actuator should be correctly aligned with the machine's moving component and should not be subjected to excessive mechanical force or unintended impact.
The 3SE50000AF02 is intended for compatible Siemens 3SE51/52 position switches.
The 3SE5 system uses a modular approach in which different actuator heads can be combined with compatible position-switch bodies.
This allows machine builders to select an actuator according to the required mechanical movement.
For replacement applications, always verify the exact existing position-switch model and actuator compatibility before ordering.
The basic operating principle is:
Moving machine component → 22 mm stainless steel roller → metal lever → position-switch mechanism → electrical switching signal
When the machine component reaches the roller, it moves the actuator lever. The lever then operates the internal mechanism of the position switch.
The resulting electrical switching signal can be used for:
The exact switching behavior depends on the compatible 3SE51/52 position-switch configuration.
The actuator can be positioned alongside a conveyor to detect the position or arrival of moving components.
Automated packaging equipment often requires mechanical position feedback. The roller lever can detect movement at defined machine positions.
It can be used for suitable machine-travel and end-position monitoring applications.
The actuator can provide mechanical position feedback for automated production equipment.
The stainless steel roller can provide a durable interface for moving machine components in material-handling equipment.
Machine builders can select the actuator head separately according to the mechanical arrangement of the machine.
The 22 mm stainless steel roller provides a robust contact surface for repeated mechanical interaction.
Potential advantages include:
Actual suitability depends on the machine's operating speed, mechanical force, environment, and installation arrangement.
Position switches are commonly installed at specific points in machinery to determine whether a mechanical component has reached its required position.
For example, a roller lever can be mounted near the end of a machine's travel path. When the moving component reaches the defined position, it contacts the stainless steel roller and actuates the position switch.
The resulting signal can be used to:
The control system and safety logic must be designed according to the specific machine requirements.
The 3SE50000AF02 provides a ready-made actuator solution for compatible Siemens 3SE51/52 position switches.
Instead of developing a custom roller mechanism, OEMs can use the appropriate Siemens actuator head within the modular 3SE5 system.
This can help with:
The separate actuator-head configuration is useful when the position-switch body is still serviceable but the actuator has become damaged or worn.
Before replacing the actuator, maintenance teams should compare:
Using the correct actuator helps maintain the intended mechanical operation of the position-switch assembly.
For reliable operation, the actuator should be installed so that the machine component contacts the roller smoothly.
Important considerations include:
The actuator should not be treated as a mechanical stop unless the complete installation has been specifically designed for that purpose.
The actuator head is a mechanical component and does not independently provide a safety function.
Where the associated 3SE51/52 position switch is incorporated into a safety-related machine function, the complete assembly—including switch, actuator, mounting arrangement, wiring, safety controller or relay, and safety architecture—must be appropriately selected and validated.
Always follow Siemens installation and application requirements for safety-related configurations.
The Siemens SIRIUS 3SE5 family provides a modular range of position-switch components and accessories.
Depending on the application, the system can include:
This modular design makes it easier to select the appropriate mechanical interface for different machine configurations.
