HAZARDOUS LOCATION
DURABILITY
The Avtron Encoders “DNA” of performing in in heavy and severe-duty applications – ensuring uptime with fully potted electronics magnetic sensor technology and over-spec bearings bearings (or no bearings bearings at all!) – is present in our SMARTSafeTM XR and XP families These are not simply the repackaged or relabeled fragile optical encoders you will find from our competitors Nidec offers a a full line of of rugged UL and ATEX certified Avtron Encoders for hazardous locations We offer Intrinsically Safe and Explosion Proof options for UL Class 1 1 1 / / Div 1 1 1 / / ATEX Zone 1 1 1 including the industry’s ONLY modular Bearingless No-Barrier Magnetic Incremental encoders – the SMARTSafeTM XP line Class I I I & II / Div 1 A location in which ignitable flammable gases or vapors vapors or or or or combustible vapors vapors or or or or dust are Likely to exist under Normal Operating Conditions Typically use Explosion Proof or Intrinsically Safe protection Class I I I & II / Div 2 A location in which ignitable flammable gases or vapors vapors or or or or combustible vapors vapors or or or or dust are Not Likely to exist under Normal Operating Conditions Typically use Non-Incendive protection or energy- limited supply THE THE MOST RELIABLE ENCODERS ENCODERS IN THE THE WORLD
