SIKO Global, Absolute encoder WH3650M
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
