German VS Sensorik encoder, VS Sensorik model, VS Sensorik price

VS Sensorik encoders are a type of digital sensor, belonging to the code disk encoder category. Code disk encoders are also known as absolute encoders; they convert angles into digital codes and can be easily connected to digital systems (such as microcomputers). Contact encoders consist of a code disk and brushes. The code disk uses printed circuit board manufacturing processes to create a disk-shaped PCB with a specific code pattern on a copper-clad laminate. A brush is a movable contact structure; under external force, when the code disk rotates, the contact point between the brush and the code disk generates a digital code output in a specific coding format.

VS Sensorik encoder classification

According to working principle, encoders can be divided into incremental and absolute types. Incremental encoders convert displacement into periodic electrical signals, which are then converted into counting pulses, using the number of pulses to represent the magnitude of displacement. Each position of an absolute encoder corresponds to a definite digital code, so its indication depends only on the start and end positions of the measurement, not on the intermediate process. Rotary incremental encoders output pulses during rotation, and their position is determined by counting equipment. When the encoder is stationary or power is lost, the position is retained by the internal memory of the counting equipment. Thus, after a power loss, the encoder must not move; when power is restored, pulses must not be lost due to interference during output, otherwise the zero point remembered by the counting equipment will shift. The amount of this shift is unknown and can only be detected when erroneous production results occur. The solution is to add a reference point; each time the encoder passes the reference point, the reference position corrects the memory position of the counting equipment. Before the reference point, position accuracy cannot be guaranteed. Therefore, in industrial control, methods such as finding the reference point before each operation or finding zero at startup are used. For example, the positioning of printers and scanners uses the principle of incremental encoders; each time they are powered on, we hear a rattling sound as they find the reference zero point before starting work.

VS Sensorik encoder features

1) After the encoder is powered on or after internal/external power faults, no reference drive is required; once power is normal, the current accurate position is immediately available. Under interference from various harsh environments, the raw position test data of hollow shaft encoders remains stable and is not easily affected by interference. 2) The encoder can provide an incremental pulse code value for each axis position, especially in position control. Incremental encoders do not require counting, enabling direct high-speed internal reading and external output. Furthermore, hollow shaft encoders reduce the cost of additional input components by handling subsequent calculation tasks in the receiving device controller. For example, hollow shaft encoders in multi-axis parallel industrial robots enable high-speed multi-axis parallel synchronous operation, as well as in various control fields requiring multi-axis synchronization. 3) Fast and reliable digital data transmission is currently one of the core elements of encoders. Due to their high-resolution characteristics, hollow shaft encoders generally output digital signals directly without internal or external counting, thus avoiding the influence of pulse reading and accumulation. They respond at high speeds; even in high-efficiency equipment, hollow shaft encoders achieve high-resolution performance. 4) Additionally, this encoder is highly flexible, characterized by compactness and ease of adjustment; positions are generally adjusted flexibly via spring leaves. Hollow shaft encoders determine the rotation direction based on the numerical value of pulse signals from A phase pulse signals and B phase output timing. Currently, hollow shaft encoders are suitable for various application scenarios. 5) The clamping method and spring leaf structure of this shaft encoder allow for easy position adjustment and absorption of load vibration and shock. Moreover, hollow shaft encoders output based on the rotational displacement of the shaft during operation; when coupled with the shaft, they can directly detect rotational displacement. Typically, no origin reset is required at startup; under normal conditions, the rotation angle can be output in parallel as an absolute value.
