Performance highlights E100 Intrinsically safe linear position sensor

The E100 intrinsically safe linear position sensor delivers accurate and repeatable displacement feedback in harsh and hazardous environments. It offers non-contact inductive sensing, eliminating mechanical wear and ensuring long-term reliability in cylinder integration.

Usage conditions

Designed for hydraulic or pneumatic cylinder applications in explosive gas and dust atmospheres, the E100 is ATEX / IECEx / UKEX certified (Ex II 1GD) and operates in temperature ranges from -40°C to +80°C. It withstands hydraulic pressure up to 350 bar and is environmentally sealed to IP67.

Possible applications

  • Position sensing in hydraulic or pneumatic cylinders
  • OEM applications in oil & gas, mining, and chemical sectors
  • Mobile machinery and heavy industrial equipment
  • Measurement systems in Zone 0 and Zone 20 environments
  • Test benches for explosion-proof development testing

Advantages of choosing this product

With high accuracy, temperature stability, and rugged stainless steel construction, the E100 ensures reliable measurements even under demanding conditions. It can be customized to match any stroke length between 5 mm and 800 mm, offering tailored precision. Optional five-wire connections maintain accuracy over long cable runs.

Other important features:

  • Ratiometric analog output (0.5–4.5 V)
  • Full EMC compliance (EN 61000-6-2, EN 61000-6-3)
  • Compatible with Althen X005 galvanic isolation amplifier
  • Multiple mounting thread options: M20x1.5, 3/4-16 UNF, M18x1.5
  • Target tube options for major OEMs like Temposonics and Parker Hannifin
