More information

Rotary encoders that can be combined with this wire-actuated encoder

"You can find suitable rotary encoders on our website www.siko-global.com. They are suitable …
  • for analog outputs such as current or voltage: AV3650M
  • for incremental outputs: IV2800
  • for absolute outputs: WV3650M, WV36M/CAN
SIKO rotary encoders have the following interfaces, among others: incremental, SSI, CANopen, IO-Link
The technical specifications for these devices can be found in the respective data sheets. In addition, numerous encoder variants from different manufacturers can be used.

Hint for mounting

When securing the wire it must be ensured that the wire is straight and vertical in relation to the wire outlet. Recommendation: Only select the starting position after an unwound length of approx. 5 mm. This prevents the wire hitting the end stop when it is rewound.
