Draw-Wire Encoder SG121

robust design with 12 m measurement length

Three in one – wire-actuated encoder with integrated inclination sensor for position, speed and inclination

Mobile machines such as mobile cranes or lifting platforms are exposed to harsh environmental conditions, which their components must withstand at all times. At the same time, installation space is at a premium, so the more compact and smarter a component, the easier it is to install and integrate.  SIKO’s PURE.MOBILE line of wire-actuated encoders was specifically developed for mobile machines.  With the optional integration of inclination sensors, they meet the requirements for high precision with little assembly and cabling effort, even in safety-critical areas of application
 
Various measured variables must be detected via different sensors to ensure the safe use of mobile machines. Wire-actuated encoders, for example, detect the linear position of mobile elevating work platforms, while separate rotary encoders or inclinometers detect the installation angle of the boom. However, too many components result in higher installation and commissioning costs.
 
As a sensor specialist for mobile machines, SIKO GmbH is now providing a smart sensor solution:  the PURE.MOBILE family of wire-actuated encoders feature an optional integrated single-axis inclinometer that can also detect the inclination. Thanks to its modular sensor design, every SIKO draw-wire encoder can thus be expanded to include inclination detection without changing the sensor’s design, size or connection type. Installation space, cabling work and product costs can be reduced in this way – with increased functionality.
 
The SG121 and SG150 wire-actuated encoder types provide maximum measuring lengths of 12,000 and 15,000 mm respectively. For mid-range measuring lengths, you can select the SG31 and SG61 wire-actuated encoders that feature maximum measuring lengths of 3,000 mm and 6,000 mm respectively.
 
The latest-generation integrable inclinometer measures inclinations in the range of ±180°. With its resolution of up to 0.001° and precision of ±0.2°, it provides high precision even in case of minor deflections. Compared to what’s available on the market, it stands out in particular thanks to its integrated temperature compensation, which ensures stable values over the entire measurement and temperature range. The sensor data can be transmitted independently of the position value via CANopen, CANopen Safety or SAE J1939 interface.
 
The SG121 and SG150 wire-actuated encoders are available in both redundant and non-redundant position and inclination detection variants. As a result, the sensors can also be used in safety-critical applications up to performance level d.
 
SIKO developed the PURE.MOBILE sensors specifically for mobile machines to meet their special requirements. The sturdy housings of the sensors make them extremely robust and very compact, enabling them to provide precise and reliable measured values even when exposed to harsh environmental conditions. For example, they feature significant EMC, shock and vibration resistance as well as E1 certification from the German Federal Motor Transport Authority.
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.
