Absolute encoder WH3650M
compact hollow shaft rotary encoder with SSI and IO-Link
The WH3650M rotary encoder is an absolute magnetic single- and multi-turn rotary encoder, which impresses with its extremely compact design. It is particularly robust and resistant to vibrations. Thanks to its high degree of protection up to IP67 and a temperature range of -40° C … +85° C, it is also suitable for demanding industrial applications. The particularly small design with a diameter of only 36 mm predestines the rotary encoder for use in applications with limited installation space. Thanks to the IO-Link and SSI interfaces, it is ready for Industry 4.0 and ideally suited for point-to-point communication in automation networks.
- Absolute wear-free magnetic encoder
- Multiturn without gearbox and without battery
- Interface SSI, IO-Link
- Extremely compact and very robust design
- IP67 protection class
- Extensive temperature range -40 … 85° C
- Optimal price-performance ratio
- Industry 4.0 ready

Industry 4.0
In most cases, data exchange with the absolute rotary encoder is limited to the exchange of process data. In addition to the process data, the rotary encoder provides additional information with an IO-Link interface that can be evaluated for condition monitoring up to predictive maintenance:
