Linear LVDT with Integrated Electronics SM40 Series

LVDT with Electronics | Stroke 20 mm to 360 mm | IP67/IP68 Protection | Output 4-20mA / ±10V | Housing Ø 25 mm | Frequency 800 Hz | PCD Mounting 30.0 mm

He Linear LVDT The Schreiber SM40 series is the flagship displacement measurement device with integrated electronics for long-travel industrial applications. Designed in a robust stainless steel housing... 25 mm in diameter, This inductive transducer eliminates the need for external signal conditioners by processing the signal internally and delivering standard mA or Vcc outputs. This compact architecture ensures a signal stability and EMI immunity superior, allowing a 1:1 compatibility / drop-in replacement in heavy machinery, hydraulic presses and automation systems where long-term reliability is non-negotiable.

This displacement transducer It achieves measurement ranges of up to 360 mm, maintaining exceptional linearity of 0.5% and a dynamic response of 800 Hz. Thanks to its IP67/IP68 protection rating and multiple mechanical options (spring-loaded probe, ball joints, or fiberglass protective sheath), the SM40 is suitable for even the harshest and most contaminated environments. It is the ultimate technical solution for engineers seeking a robust position sensor with infinite resolution and easy direct integration into PLCs via an M12 connector or cable output.
