Siemens 3SE5112-0CA00 Position Switch, Metal Enclosure, 1NO+1NC Snap-Action Contacts

The Siemens 3SE5112-0CA00 position switch is a high-quality industrial component engineered for precision and durability in demanding automation environments. Housed in a robust metal enclosure, this switch provides reliable performance and long-term protection against mechanical stress. It features a versatile 1NO+1NC snap-action contact configuration, ensuring rapid and accurate switching operations. As a modular unit supplied without an actuator, it offers significant flexibility, allowing users to select and install the specific actuator head required for their unique machine safety or position monitoring tasks.

Advantages

The primary benefit of this Siemens position switch is its exceptional build quality, which ensures consistent operation even in harsh industrial settings. The metal housing provides superior resistance to impact and environmental factors compared to plastic alternatives. The snap-action contact mechanism guarantees a clean and definitive switching signal, which is essential for safety-critical applications. Furthermore, the modular design allows for easy integration into existing systems, as the absence of a pre-installed actuator enables custom configuration to meet precise mechanical requirements.

Suitable for

• Industrial automation systems
• Machine safety monitoring
• Position detection of moving parts
• Conveyor belt control systems
• Automated assembly lines

When it may not be suitable

This switch is not suitable for applications requiring a specific actuator type if you do not have the compatible Siemens 3SE5 series actuator head available for installation. It is also not intended for use in environments where specialized chemical resistance or non-metallic housing materials are strictly mandated by safety regulations.

Key specifications

• Contact configuration: 1NO (Normally Open) + 1NC (Normally Closed)
• Switching mechanism: Snap-action
• Enclosure material: Metal
• Modular design: Supplied without actuator
• Application: Industrial position sensing

How to use

To use the Siemens 3SE5112-0CA00, first select a compatible actuator head from the Siemens 3SE5 series that matches your mechanical application. Securely mount the switch body to a stable surface using the provided mounting holes. Once the switch is positioned, attach the chosen actuator head to the top of the unit. Connect the electrical wiring to the 1NO and 1NC terminals according to your control circuit diagram. Ensure that the actuator is correctly aligned with the moving part of the machine to trigger the switch at the desired position.

What to consider before purchase

• Verify that you have a compatible actuator head for this switch body.
• Check the physical dimensions to ensure it fits your mounting space.
• Ensure the electrical ratings match your control system requirements.
• Confirm that the metal enclosure is suitable for your specific environmental conditions.

Usage recommendations: Regularly inspect the switch for mechanical wear and ensure that the actuator remains properly aligned. Periodically test the snap-action contacts to confirm they are triggering correctly within your safety circuit.
