BEI Sensors full line of UL-certified nonincendive Division 2 encoders are now compliant to CENELEC/ATEX and IECEx non-sparking Zone 2 hazardous area standards. This triple certification is provided on six popular heavy-duty encoder models sized 2 to 4.5 inches in both hollow shaft and shafted versions. These models include the H20, H25, HS20, HS25, HS35, and HS45.
The non-incendive/non-sparking protection method assures that no sparking or hot surfaces will occur in the encoders under normal operating conditions. Encoders with this certification offer several operational benefits including simpler installation, no need for an associated apparatus (such as a barrier) and no restriction of energy to the hazardous location. These encoders also take up less space in the application and are often less costly than encoders designed for more stringent hazardous locations such as Division 1, Zone 0 or Zone 1.
Triple ratings for these hazardous area encoders also help to simplify the certification process of the end-users assembly and save costs in obtaining additional approvals to comply with international safety regulations. In applications where explosive agents are only present in abnormal operating conditions, non-incendive/non-sparking encoders can be used instead of more expensive explosion-proof or flameproof products that exceed the hazardous area requirements of Division 2 and Zone 2 environments.
