Wraising the bar for simultaneous
position and speed monitoring solutions in
heavy-duty applications to a new level of
performance. The new universal encoder
system not only reduces costs while
significantly increasing switching accuracy,
it also offers a wide range of useful
additional functions.
For applications requiring functional
safety up to SIL 2 to DIN 61508 and PL

step-up gearing. • Extremely economical thanks to the low overall operating costs
This translates to a significant - Attractive purchase price
reduction in investment, maintenance and - Simple to install
installation costs while at the same time - Time saving start-up
allowing you to improve system accuracy - Low standstill costs during maintenance tasks
and implement useful additional functions. - Long service life
The UOC 40 guarantees rapid availability • High levels of availability in extreme operating conditions
following initial installation, maintenance - Robust housing
