Resistant, smart, compact: Encoders for harsh environments

The AHS/AHM36 IO-Link Inox absolute encoders set standards in resistance to environmental influences and IO-Link communication. Due to the stainless-steel design and enclosure rating IP69, the encoders are suitable for use in very harsh ambient conditions.

With various mounting hole patterns and adapter flanges, the AHS/AHM36 IO-Link Inox absolute encoders fit into nearly every application. The IO-Link interface enables economical encoder integration into Ethernet and fieldbus networks. The configuration can be adjusted individually using SOPAS or IO-Link master. The rugged, reliable, fully magnetic sensor system achieves a maximum resolution of 14 bits for the singleturn variant and maximum 26 bits for the multiturn variant.
