H117 Slim-line linear position sensor

Compact and intrinsically safe sensor for precise position measurements in hazardous areas.


Key features

  • Intrinsically safe for gas and dust zones
  • Custom travel lengths from 5 to 350 mm
  • High accuracy and long-term stability
  • Compact 19 mm stainless steel housing
  • Sealed to IP67, robust and durable
  • Infinite resolution and >10 kHz response

Performance highlights

The H117 Slim-line linear position sensor delivers high-precision measurements with exceptional stability and repeatability across a wide temperature range. Designed for demanding environments, the sensor uses non-contacting inductive technology, ensuring no mechanical wear and long-term reliability.

Usage conditions

Certified for use in hazardous gas and dust atmospheres (Class I/II/III, Division 1), the H117 meets stringent CSA intrinsic safety standards. It operates reliably from -40°C to +80°C, features IP67 sealing, and offers EMC compliance for industrial environments.

Possible applications

  • Position feedback in hazardous process plants
  • Displacement monitoring in offshore and petrochemical environments
  • OEM integration in ATEX/IECEx rated equipment
  • Feedback systems for hydraulic cylinders
  • Robotics and mechanical automation in Zone 0/20 areas

Advantages of choosing this product

The H117 is especially valued for its customizable travel range, robust stainless steel construction, and compatibility with the G005 galvanic isolation amplifier. The sensor’s compact 19 mm diameter makes it ideal for confined spaces, while the choice of connector and push rod options supports flexible integration.

Other important features:

  • EMC performance: EN 61000-6-2, EN 61000-6-3
  • Vibration resistance: 10 g (IEC 68-2-6)
  • Shock resistance: 40 g (IEC 68-2-29)
  • Optional sprung push rod and rod eye configurations
  • Sensor output: 0.5 – 4.5V ratiometric with 5V supply
