SICK encoder ARS60-FAL01024 in stock

The core working principle of the Sik encoder is to convert the position, angle, or velocity of mechanical motion into electrical signals for output. The specific principles of different types of encoders vary. The following is an introduction to the working principles of the main types:

incremental encoder

The core components include a code wheel, a light source, and a photoelectric receiving element. The code wheel is engraved with evenly distributed transparent and opaque stripes.

When working, the light emitted by the light source passes through the code wheel, and as the code wheel rotates, the transparent stripes and opaque stripes alternately block the light. The photoelectric receiving element converts the light signal into a pulse electrical signal.

The control system calculates displacement or angle by counting the number of pulses, and calculates velocity by pulse frequency. This type of encoder requires a reference point to determine the absolute position.

Absolute value encoder

The code wheel is engraved with a unique binary encoding pattern, with each position corresponding to a code.

After the light source illuminates the code wheel, the photoelectric receiving element reads the encoded information of the current position and directly converts it into a digital electrical signal output.

Regardless of whether the power is cut off or not, the current absolute position information can be immediately output after powering on again, without the need for recalibration or zeroing.

The multi turn absolute value encoder also records the position after multiple rotations through mechanical gear sets or electronic counting methods, achieving a wider range of position measurement.

Linear encoder

Divided into optical and magnetic types, the core is to convert linear displacement into electrical signals.

The optical linear encoder works with a grating ruler (similar to a linear encoder) and a reading head. Light passes through the engraved lines of the grating ruler to produce Moir é fringes, which are then converted into electrical signals by the reading head to measure displacement.

The magnetic linear encoder utilizes the magnetic scale on the magnetic grid ruler to generate an electrical signal by inducing magnetic field changes through the magnetic head, achieving linear displacement detection.

Measuring wheel encoder

The measuring wheel comes into contact with the surface of the object being measured, and when the object moves, it drives the measuring wheel to rotate. The rotational motion is transmitted to the built-in incremental or absolute encoder core.

The encoder converts the rotation of the measuring wheel into an electrical signal, and combines it with the circumference of the measuring wheel to calculate the distance and speed of the object being measured.
