This reliable switch is ideal for monitoring the position of moving machine parts in demanding industrial environments.

## Long description

The Siemens SIRIUS 3SE5112-0CH51 is a high-performance position switch engineered for precise position sensing and monitoring of moving machine parts in industrial environments. Housed in a durable 40 mm metal enclosure compliant with EN 50041 standards, this device ensures long-term reliability and resistance to mechanical stress. It features a versatile rotary actuator that can be adjusted for left or right operation, paired with an adjustable-length metal lever and a stainless steel roller for optimal mechanical interaction.
Advantages
This position switch offers exceptional flexibility through its modular design, allowing it to adapt to a wide range of industrial applications with minimal inventory requirements. The snap-action contact mechanism provides clear and reliable switching signals, while the robust metal construction ensures protection against harsh environmental conditions. Installation is streamlined thanks to the quick-connect technology, which significantly reduces setup time. Furthermore, the device supports high safety standards, enabling compliance with demanding requirements such as PL e or SIL 3 when configured correctly.
Suitable for
Monitoring the position of machine components
Safety gate and protection equipment monitoring
Industrial automation systems
Applications requiring EN 50041 compliance
When it may not be suitable
This switch may not be appropriate for environments involving extreme chemical exposure that could degrade the metal housing or stainless steel components. It is also not intended for applications requiring non-contact sensing technologies, such as inductive or capacitive proximity sensors, where physical contact with the actuator is not possible or desired.
Key specifications
Enclosure width: 40 mm
Contact configuration: 1 NO / 1 NC (quick action)
Actuator type: Rotary lever with adjustable length
Roller material: Stainless steel (19 mm)
Connection type: 1x M20 x 1.5
Standards compliance: EN 50041, IEC, UL
How to use
The switch should be mounted securely to the machine frame using the designated mounting points in accordance with EN 50041. Ensure the rotary actuator is positioned so that the metal lever makes consistent contact with the moving machine part. Connect the electrical wiring to the 1 NO/1 NC contacts through the M20 cable entry. After installation, perform a mechanical test to verify that the lever triggers the switch at the intended position and that the contact state changes correctly as expected by your control system.
What to consider before purchase
Verify that the 40 mm enclosure size fits your mounting space requirements.
Ensure the 100 mm adjustable metal lever provides sufficient reach for your specific machine part.
Check that your control system is compatible with the 1 NO/1 NC snap-action contact configuration.
Confirm that the environmental conditions are suitable for a metal-housed mechanical switch.
Usage recommendations
Regularly inspect the stainless steel roller and the lever mechanism for signs of wear or debris accumulation to ensure consistent performance. Periodically verify the electrical connections and the integrity of the cable gland to maintain the enclosure's protective rating.
