Siemens 3SE5112-0CD02 Position Switch with Roller Plunger

The Siemens 3SE5112-0CD02 position switch with roller plunger is a high-performance industrial component engineered for precise position detection and limit monitoring. Housed in a rugged metal enclosure, this switch is designed to withstand the rigors of demanding industrial environments while providing consistent mechanical switching performance. Its snap-action contact mechanism ensures reliable signal transmission, making it an essential element for automated control systems.

Advantages

This position switch offers exceptional durability due to its robust metal housing, which provides superior protection against mechanical impacts and environmental factors. The roller plunger actuator design allows for smooth operation and high-precision triggering, even in applications involving frequent mechanical movement. With its snap-action contacts, the device guarantees a clear and definitive switching state, minimizing the risk of contact bounce and ensuring long-term operational stability in complex automation setups.

Suitable for

• Machine tool manufacturing and control
• Conveyor belt systems and logistics automation
• Limit monitoring in automated assembly lines
• Position detection for moving machine parts

This switch may not be suitable for applications requiring non-contact sensing, such as those involving high-speed proximity detection without physical contact. It is also not intended for use in explosive atmospheres or environments with extreme chemical exposure unless specifically protected by additional housing.

Key specifications

• Actuator type: Roller plunger
• Enclosure material: Metal
• Contact configuration: Snap-action
• Application: Industrial automation and limit monitoring

To install the switch, mount it securely to a stable surface using the provided mounting points, ensuring the roller plunger is correctly aligned with the moving object. Connect the electrical wiring according to the terminal diagram to ensure proper contact closure and opening. Regularly inspect the actuator for signs of wear or misalignment to maintain optimal performance.

What to consider before purchase

• Verify the mechanical travel distance required for your specific application
• Ensure the mounting dimensions are compatible with your existing equipment
• Confirm the electrical load requirements match the switch contact ratings

Usage recommendations: For optimal longevity, ensure the roller plunger is not subjected to excessive side-loading forces. Periodically check the mounting hardware for tightness and ensure the actuator remains free of debris or heavy dust accumulation.
