SIEMENS SITRANS LCS050 Capacitance Point Level Switch


& Free Shipping

Siemens SITRANS LCS050: With its ultra-compact design and short insertion length of just 15 mm (0.59 inches), this versatile device is perfect for a wide range of vessel or pipe applications, serving as an ideal replacement for traditional point level switches.

Equipped with an advanced alternating capacitance field at the sensor tip, the LCS050 ensures precise material detection through capacitance changes, delivering consistent performance every time.


The PEEK probe boasts chemical resistance and supports an effective operating temperature range from -20 to +100 °C (-4 to +212 °F), enabling sterilisation in place at temperatures up to 135 °C (275 °F) for up to 1 hour. Engineered for reliability even in vibrating environments such as agitated tanks, withstanding up to 5 g.

  • Easy installation with no need for adjustment
  • Low maintenance with no moving parts
  • Highly visible 360-degree status indication
  • M12 connector for ease of installation
  • IO-Link communication option for advanced monitoring and configuration
