Absolute encoder WH3600MR

Magnetic safety rotary encoder with hollow shaft

open expert video

The smallest safety multiturn rotary encoder for mobile machines! Specially developed for use in mobile machines, the absolute safety rotary encoder WH3600MR provides reliable and precise measured values even under the toughest environmental conditions. Thanks to the innovative safety concept, certified according to SIL2, the WH3600MR can also be used in safety-critical applications up to performance level d. Available as a singleturn and multiturn version and with an outer diameter of only 36 mm, it can also be mounted in applications with extremely limited installation space.

Profile WH3600MR:

Smallest safety multiturn rotary encoder for mobile machines
Single turn or multiturn variant available
SIL2 (IEC 61508) PLd (DIN EN ISO 13849) certified (in preparation)
E1 approval by the German Federal Motor Transport Authority (KBA) pending
Extremely compact and very robust design
Protection class up to IP6K9K
With PURE.MOBILE technology
