X117 Slim-line linear position sensor

Compact intrinsically safe sensor for precise displacement feedback in hazardous gas and vapor environments.


Key features

  • Intrinsically safe for hazardous gas
  • Compact 19 mm stainless steel body
  • Travel range 5 to 350 mm
  • High accuracy and repeatability
  • IP67 environmental protection
  • Custom mounting and push rod options

Performance highlights

The X117 slim-line linear position sensor delivers accurate and stable displacement measurements in demanding industrial environments. Using non-contact inductive technology, it ensures long-term reliability without wear.

Usage conditions

With ATEX, IECEx and UKEX certification (Ex II 1G, Ex ia IIC T4 Ga), the X117 is intrinsically safe and approved for use in gas and vapor hazardous areas, even under continuous exposure. It operates reliably from –40 °C to +80 °C and offers EMC protection and sealing to IP67.

Possible applications

  • Valve and actuator position monitoring
  • Process control in hazardous areas
  • Test and measurement equipment
  • OEM sensor integration in industrial systems
  • Feedback control for cylinders and machinery

Advantages of choosing this product

The X117 combines compact size with robust stainless steel construction, making it ideal for space-limited installations. It supports both three-wire and five-wire connections for optimized accuracy with long cable runs. Each unit is factory-calibrated to customer-defined travel, ensuring maximum precision.

Other important features

  • Frequency response > 10 kHz
  • Infinite resolution and low noise < 0.02% FSO
  • Customizable push rod (thread, rod eye, or magnetic tip)
  • Optional spring-loaded push rod in both directions
