Description
Siko SG31 Draw-Wire Encoder
Siko SG31 Draw-Wire Encoder is a very robust wire-actuated encoder in a compact design for numerous applications including crane construction, stage construction, warehousing technology, etc., with a measuring length of up to 3000 mm. Easy, universally changeable installation. 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.
Length measurement technology with Siko SG31 Draw-Wire Encoder
SIKO wire-actuated encoders have been in use for many years in the field of length measuring technology and have already proved their worth in different conditions, including difficult conditions Robust compact design, with maximum precision and reliability are the criteria that are set as the most important goals for every new development in this area.
Only a wire-actuated encoder can be used as a linear measured displacement encoder for many applications because no guided sensor systems can be used due to the spatial constellation.
Wire-actuated encoders are flexible with respect to integration and interfaces
The easy assembly and guiding of the wire pull-out mean that the measuring system can be integrated into existing systems simply and flexibly. Different interfaces and output signals make it possible to connect to a vast range of different control concepts.
Wire-Actuated Encoders Are Robust, even in Adverse Conditions
Thanks to the possibility of attaching various rotary encoders, wire-actuated encoders provide a wide range of possibilities for use, regardless of what signal output is required. The user is able to assemble the encoder himself or herself using simple means. Outdoor use, something that can never be ruled out for mobile machines, in particular, is already standard for the wire-actuated position encoders, which meet the necessary prerequisites: working temperature ranging from -40°C to +80°C, the robust casing that can include outlets by means of which fluid in the device can be drained off again.
The basic design of SIKO wire-actuated encoders
The way it works is very simple: a measuring wire is wound onto an internal drum in one layer, guaranteeing very high linearity across the entire measurement range. When the wire is pulled out, the drum rotates. The angle sensor connected directly to the drum axis registers this rotation and produces a measurement signal that is proportional to the wire movement and that can be evaluated at will. The wire is returned using a spiral spring on the rotational axis of the drum. Because the wire is simply attached to the measurement object, especially little effort is required for assembly.
