E500 Intrinsically safe rotary position sensor

ATEX & IECEx approved intrinsically safe sensors for hazardous dust environments calibrated between 16-160 degrees


Key features

  • Intrinsically safe for gas and dust (ATEX, IECEx, UKEX)
  • Non-contacting inductive technology
  • Factory-set angle from 16° to 160°
  • High frequency response >10 kHz
  • Long lifespan with rugged stainless steel housing
  • Sealed to IP67 for harsh environments

Performance highlights E500 Intrinsically safe rotary position sensor

The E500 rotary position sensor uses advanced non-contacting inductive technology to deliver high accuracy and linear output, even in extreme conditions. It offers full 360° shaft rotation and infinite resolution, with superior repeatability and stability across wide temperature ranges.

Usage conditions

Built for harsh industrial and scientific feedback applications, the E500 operates reliably from -40°C to +80°C and is protected to IP67. Its rugged stainless steel body and EMC compliance (EN 61000-6-2, EN 61000-6-3) ensure durability in dusty, wet, and hazardous zones.

Possible applications

  • Valve position feedback in ATEX zones
  • Rotational angle feedback in industrial automation
  • Rotary displacement in scientific measurement systems
  • OEM machinery requiring compact explosion-proof sensors

Advantages of choosing this product

Designed for OEMs and system integrators, the E500 offers intrinsic safety (Ex II 1GD) with flexible mounting options, fast delivery, and customization possibilities. The sensor is factory-calibrated to user-specified angles (16°–160°) and ensures outstanding reliability, even with long cable lengths (up to 1000m using 5-wire configuration).

Other important features

  • Temperature coefficient: <±0.01%/°C (gain and offset)
  • Torque: <20 mNm static
  • Noise: <0.02% FSO
  • Mounting: Flange or servo
  • Optional spring-loaded shaft
  • 3-wire or 5-wire configuration based on cable length
  • Certification: SIRA, IECEx, CSAE
