H505 Slim-line rotary sensor (intrinsically safe)

Compact rotary sensor with high accuracy and CSA certification for hazardous dust and gas zones. Designed for OEMs where space, reliability and safety matter.


Key features

  • Certified for hazardous dust and gas zones
  • Factory-set measurement range up to 160°
  • Robust IP67-rated stainless steel housing
  • Compact 19 mm diameter body
  • Output: 0.5–4.5 V ratiometric with 5 V supply
  • High stability across temperature range

Performance highlights

The H505 slim-line rotary sensor delivers high-precision angular measurement using non-contact inductive technology. It ensures linear output over a calibrated range (15°–160°) with infinite resolution, excellent EMC protection, and low noise (< 0.02% FSO). Suitable for tight-space installations, it provides robust and accurate feedback under tough industrial conditions.

Usage conditions

This intrinsically safe sensor is CSA-approved for Class I, II, and III Division 1 areas, including Zones 0 and 20. It operates between -40 °C and +80 °C and withstands high shock (40 g) and vibration (10 g). The H505 is housed in a corrosion-resistant IP67-rated stainless steel enclosure.

Possible applications

  • Grain and dust processing environments
  • Pharmaceutical and chemical facilities
  • Robotics and automation with limited space
  • OEM equipment for hazardous locations
  • Tank lid position detection in ATEX zones

Advantages of choosing this product

With its compact footprint, full rotational freedom, and configurable output angle, the H505 is ideal for OEMs needing precise and space-efficient rotary sensing in hazardous environments. The sensor offers stable output in varying temperatures and long service life due to its wear-free inductive design.

Other important features

  • Class I, Zone 0 & Zone 20 Ex ia certified
  • Pre-calibrated to customer angle requirement
  • Servo or flange mounting options
  • EMC compliant: EN 61000-6-2, EN 61000-6-3
  • MTBF: 350,000 hrs at 40 °C
  • Galvanic isolation amplifier recommended (G005)
