Draw-wire encoder SG121

robust design with 12 m measurement length

SIKO Global, Draw-wire encoder SG121
SIKO Global, Draw-wire encoder SG121
Universally usable wire-actuated encoder with measuring lengths of max. 12000 mm, robust design as well as precise and safe wire guidance; prepared for the attachment of various types of rotary encoders with 58 mm standard flange. In combination with a safety encoder from the PURE.MOBILE sensor platform, the wire-actuated encoder can also be used in safety-critical applications up to Performance Level PLd. Furthermore, the wire-actuated encoder can also be used in safety-critical applications up to Performance Level Pld for easy parameterization.
  • Robust design
  • Easy mounting
  • Measurement lengths up to max. 12000 mm
  • Flexible wire outlet thanks to Wire-Flex technology
  • Incremental or absolute encoder
  • Also available as a safety version in combination with WV58MR rotary encoder
  • High flexibility thanks to free choice of rotary encoders with 58 mm standard flange
  • Various wire types
  • With PURE.MOBILE technology

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, AV58M
  • for incremental outputs: IV5800
  • for absolute outputs: WV58MR, WV5800M, WV5850, WV3650M, WV36M/CAN
SIKO rotary encoders have the following interfaces, among others: incremental, SSI, CANopen, CANopen Safety, SAE J1939, various fieldbus protocols
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.

Extension length/measuring range

SIKO wire-actuated encoders achieve the maximum measuring accuracy when the entire wire length (measuring range) is only wound onto the drum in one layer. On the SG121, the wire diameter is selected so that when the first drum layer is used, a maximum measuring range of 6000 mm is possible.
If a lower measuring accuracy is acceptable, two to three layer winding is also possible, and the possible measuring lengths change accordingly.
Dimensions in millimeters

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.
