HS52 ABZC SC
The HS52 is the industry’s first UL and ATEX rated explosion proof hollow shaft
encoder. Capable of operating directly in Division 1 or Zone 1 environments, the
HS52 does not need an Intrinsic Safety barrier. This provides a simpler, more
streamlined feedback system in explosion proof environments worldwide. Fitted with
a flex shaft in the bore, 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 provides
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.
