M603 Intrinsically safe large angle tilt sensor

The M603 is a rugged, intrinsically safe tilt sensor ideal for hazardous environments such as mining and industrial automation. It offers high accuracy over a wide angle range with reliable linear output.


Key features

  • Intrinsically safe for gas, vapor, dust and mining environments (ATEX/IECEx/UKEX)
  • Non-contact inductive technology with infinite resolution
  • Factory-set angle range between 15° and 160°
  • EMC compliant, IP67 sealed stainless-steel housing
  • M12 connector with adjustable mounting flange
  • High durability, low noise, and excellent temperature stability

Performance highlights

The M603 delivers precise angular position feedback using non-contacting inductive technology, ensuring no wear and outstanding reliability. It offers high repeatability and linear output throughout the specified rotation range, which is factory-calibrated between 15° and 160°.

Usage conditions

Designed for use in hazardous environments, the M603 complies with ATEX, IECEx, and UKEX standards. It operates in temperatures from -20°C to +80°C and includes EMC protection. The IP67 stainless steel housing and secure flange mounting make it suitable for harsh applications.
