Absolute encoder WH3600M

Compact magnetic rotary encoder with hollow shaft

open expert video

Specially developed for use in mobile machines, the absolute rotary encoder WH3600M provides reliable and precise measured values even under the toughest environmental conditions. Available as a singleturn and multiturn version and with an outer diameter of only 36 mm, it can also be mounted in applications with limited installation space. Despite the compact design, the WH3600M convinces with a wide variety of variants. In addition, the WH3600M has the optimum robustness thanks to its high degree of protection and salt mist-tested housing.

Profile WH3600M:

CANopen (DS406) or SAE J1939 interface
Extremely compact design with ø36 mm flange
Single turn or multiturn variant available
E1 approval by the German Federal Motor Transport Authority (KBA) pending
Salt-spray resistant housing available
With PURE.MOBILE technology
