E117 Slim-line linear position sensor

Compact and intrinsically safe position sensor for demanding linear measurement tasks in hazardous environments. Designed for OEMs and industrial integration.


Key features

  • Non-contact inductive technology
  • Slim 19 mm stainless steel housing
  • Travel range from 5 to 350 mm
  • ATEX/IECEx/UKEX approved
  • High precision with low temperature drift
  • Sealing to IP67

Performance highlights E117 Linear inductive position sensor

The E117 slim-line linear position sensor provides accurate linear displacement feedback in hazardous environments. Its robust stainless steel body and contactless inductive technology ensure long-lasting stability and reliability. It offers excellent repeatability, a frequency response above 10 kHz, and an infinite resolution for precision measurement.

Usage conditions

The sensor operates from −40°C to +80°C and is sealed to IP67. With ATEX / IECEx / UKEX approval for gas and dust zones, it is safe for Zones 0, 1, 2 and 20. It supports both axial and radial mounting options and is compatible with a wide range of connection configurations.

Possible applications

  • Process automation in hazardous areas
  • Petrochemical and oil & gas facilities
  • Industrial OEM equipment
  • Position control in machinery
  • Valve and actuator feedback

Advantages of choosing this linear position sensor

With its intrinsically safe design, the E117 is suitable for explosive atmospheres. Its modular build allows customization in travel length, push rod type, and cable connection. Easy integration and zero-maintenance operation make it ideal for space-constrained applications.

Other important features

  • Multiple cable and connector types (M8, M12, Pg9)
  • Captive or free push rod with spring return options
  • Calibration range from 5 mm up to 350 mm
  • Linear output: 0.5–4.5V ratiometric
  • EMC compliance: EN 61000-6-2, EN 61000-6-3
  • Certified for use with up to 1000 m of cable
