Explosionproof Rotary Encoder carries UL- and ATEX-rating.

Press Release Summary:




Hollow shaft encoder, HS52, can operate directly in Division 1 and Zone 1 environments, where ignitable concentrations of flammable gases, vapors, or liquids are likely to exist under normal operating conditions. Product does not require accompanying intrinsic safety barrier, and enclosure can withstand and contain internal explosion of most volatile gas-to-air mixtures. Fitted with flexible shaft bore design, housing can be rigidly mounted.

An Industry First: BEI Releases UL & ATEX Rated Explosion Proof Hollow Shaft Encoder



BEI Sensors has released the industry's first UL and ATEX rated explosion proof hollow shaft encoder, Model HS52. BEI has developed this ultra rugged and space-saving industrial encoder to meet the high standards and certifications required for use in potentially explosive environments. The HS52 is capable of operating directly in Division 1 and Zone 1 environments where ignitable concentrations of flammable gases, vapors or liquids are likely to exist under normal operating conditions. This rugged and reliable encoder does not require an accompanying Intrinsic Safety barrier, which simplifies installation and provides a more streamlined feedback system in explosion proof environments.

Using the explosion proof construction method, this rotary encoder is housed in an enclosure that can withstand and contain an internal explosion of the most volatile gas-to-air mixture. Fitted with a flexible shaft bore design, the HS52 housing can be rigidly mounted, preventing stress to encoder bearings and providing a more secure attachment for the required hazardous area conduit fittings. Additionally, the compact hollow shaft design offers engineers space-saving advantages over traditional shafted encoders. The HS52 is the ideal position sensing solution for use in oil and gas industries, solvent refining operations, spray painting applications, and explosive environments where space is limited and operating conditions are extreme.
