DURABILITY
What use is a hazardous duty encoder if it fails
to work? Many “hazardous duty” encoders from
the competition are merely repackaged weak
optical encoders.
Avtron hazardous duty SMARTSafe XR encoders
are heavy and severe duty units, with potted
electronics, magnetic sensors and huge bearings
or no bearings at all!
XRB1 isolator for remote installation; XR4F, XR45 incremental encoders with Level
Nidec-Avtron offers a full range of SMARTSafe XR 2 Local Protection
encoders including shafted, hollow shaft, and LEVEL 1 PROTECTION
modular no-bearing styles. HAZARDOUS AREA SAFE AREA
