Draw-Wire Encoder SG31

Smart sensor family for mobile machines
Wire-actuated encoders measure position, speed and inclination

Regardless of whether lifting platforms, mobile cranes or self-concrete pumps, mobile machines must always function as smoothly, precisely and efficiently as possible. Smart sensors are in demand here that reliably detect the complex movements of the machines. With the wire-actuated encoders of the PURE.MOBILE family from SIKO GmbH, whose functions can be optionally enhanced, several measured variables can be recorded simultaneously and thus assembly effort and costs can be reduced. 
 

Different sensors are necessary to detect all geometric positions of a boom/lifting mast in mobile machines or industrial trucks. In addition to wire-actuated encoders for detecting the linear position, rotary sensors or inclination sensors are also used for detecting rotational movements. All these sensors are essential for the safe workflow and stability of the machine. However, a large number of sensors also means increasing complexity due to increased cabling and assembly costs as well as higher product costs. The integrated sensor variants of the PURE.MOBILE family from SIKO GmbH, manufacturer of sensors for mobile machines, are a smart alternative that saves installation space, assembly effort and costs.
 
The central components of the PURE.MOBILE series are wire-actuated encoders of the type SG31 and SG61, which have a maximum measuring length of 3 to 6 meters. By integrating the latest generation of inclination sensors, they combine not only the detection of position and speed, but also the measured value of inclination. The two integrated inclination sensors are complemented by the large variants SG121 and SG150, which offer a maximum measuring length of 12 or 15 meters.
 
The integrated single-axis inclination sensor is available as an option and measures inclinations in the range of ±180° with a resolution of up to 0.001° and an accuracy of ±0.2°. In this way, the sensor also detects small deflections. Its integrated temperature compensation keeps the values stable over the entire measuring and temperature range. The sensor data are transmitted to the controller via CANopen, CANopen Safety or SAE J1939 interface, independent of the position value.
 
Thanks to the modular sensor design, the inclination detection can be integrated into any SIKO wire-actuated encoder without changing the design and size or connection type of the sensor. With an increasing range of functions, installation space, assembly effort and product costs on the machines can be reduced
 
The SG31 and SG61 wire-actuated encoders are also available in both redundant and non-redundant position and inclination detection variants. As a result, they can also be used for safety-critical applications up to performance level d.
 
All PURE.MOBILE sensors have been developed according to the requirements of mobile machines and are extremely robust. This includes an E1 approval from the Federal Motor Transport Authority as well as high EMC, shock and vibration resistance. The sensors are installed in compact housings and always provide reliable and precise values, even under harsh environmental conditions.
