Incremental encoders generate signal periods or signal sequences of pulses whose frequency is proportional to the rotational speed. The number of pulses per revolution determines the resolution. Counting the pulses makes it possible to record positions and rotation counts as well. The stainless steel types are particularly suitable for use under challenging ambient conditions. SICK also offers incremental encoders with a functionally safe design that support safety functions according to IEC 61800-5-2.
Absolute encoders generate unique position values. Depending on the requirements, information about the position, angle of rotation or speed can be derived. For singleturn variants, the resolution describes the number of possible steps per revolution. A multiturn encoder type also records the number of revolutions. The stainless steel variants are particularly suitable for use under challenging ambient conditions. SICK also offers absolute encoders with a functionally safe design that support safety functions according to IEC 61800-5-2 and applications for safe positioning.
Wire draw encoders consist of a wire draw mechanism and an encoder. The rotation of the drum, which is proportional to the length being measured, is recorded and output by an encoder. This facilitates positioning on linear measuring paths. SICK's wire draw encoders support a large selection of interfaces and facilitate easy system integration for applications in challenging industrial settings. Different performance classes make it possible to select the ideal device for the application at hand.
Linear encoders detect linear movements as absolute position values without making contact. No reference run is required for the wear- and maintenance-free encoders. Different constructions with high resolution and rugged design enable use in a wide range of applications and industries.
Position data of objects is indispensable for the automation of processes, especially in demanding and mobile applications. SICK offers a wide range of inertial sensors for this purpose, for both simple static and highly dynamic applications.
