Explosion Proof Ex d Hall Effect Sensors

Motion Sensors explosion proof sensors are certified (ATEX compliant with 2014/34/EU,) IECEx and comply with the essential health and safety requirements relating to the design and construction of equipment and protective systems intended for use in potentially explosive atmospheres.


Explosion Proof (Ex d Certified) version of the H and HN Hall Effect sensors are available.

Physical Features

  • Body material: 300 series stainless steel
  • Epoxy encapsulation
  • Magnet that resists demagnetization
  • IR leakage: 100 Mohms @ 100 VDC min.
  • High Shock and Vibration resistance (MIL-STD-202G METHOD 214A, Test Condition H)

Interconnection Options

  • Male or Female NPT threaded body with wire or cable pigtail for explosion proof environments
  • Cylindrical Male or Female thread types also available; e.g. M10 through M20

Mounting Thread Options

  • Threaded options range from 3/8-24 through 3/4-20 or M10 through M20
  • Body can also be smooth with no mounting threads
