H130 Long stroke in-cylinder linear position sensor

Intrinsically safe linear sensor for hydraulic and pneumatic cylinders with long stroke range and high durability.


Key features

  • Intrinsically safe for gas and dust zones
  • Wear-free inductive technology
  • Custom stroke lengths from 0–1485 mm
  • Output: 0.5–4.5 V ratiometric
  • Sealing to IP67, stainless steel housing
  • High accuracy and EMC compliant

Performance highlights

The H130 is a high-performance linear position sensor with intrinsically safe design for hazardous environments. Its non-contact inductive technology ensures long service life without wear and delivers outstanding accuracy and stability over a wide temperature range.

Usage conditions

Designed for in-cylinder integration in hydraulic and pneumatic applications, this sensor operates reliably in harsh environments, with protection ratings up to IP67 and vibration resistance up to 10 g. Its stainless steel housing and fluoropolymer-sheathed probe ensure durability even in demanding settings.

Possible applications

  • Hydraulic cylinder position monitoring
  • Pneumatic actuator feedback
  • Offshore and marine installations
  • Explosive gas and dust zone environments
  • OEM equipment in hazardous areas

Advantages of choosing this product

Thanks to CSA-approved EX08 electronics, this sensor can be safely deployed in Zones 0, 1, 2 (gas) and Zones 20, 21 (dust). The flexible stroke length customization and excellent EMC protection make it a robust and versatile option for OEMs and end users alike.
