At this year’s SPS/IPC Drives,
Johannes Huebner Giessen released
two new absolute encoders with SIL
certification that have been
developed for use in heavy duty
applications.

The AMP(H) 41 (Profibus) and
AMPN(H) 41 (Profinet) are certified
to Safety Integrity Level (SIL) 3 in
accordance with German industry
standard DIN EN 61508 and to EN
ISO 13849-1 up to performance
level (PL) ‘e’.

As of spring 2013, these encoders
will be available in two versions: AMP
41 or AMPN 41 with a solid shaft (14
mm in diameter) for mounting the
encoder using a coupling, and the
AMPH 41 or AMPNH 41 with a
continuous hollow shaft (20 mm in
diameter) for direct mounting of the
encoder on the drive shaft.
