H20DB-37-SS-250-AB-15V/OC-SM16-S application field and working principle

Encoder is a device which could convert motion information into electrical signals, and send out different meanings signals according to the type and quantity of motions. The H20DB-37-SS-250-AB-15V/OC-SM16-S type encoder is a kind of absolute encoder, and its application field includes consumer electronics, automotive electronics, and some industrial fields. It has high precision, linearity, stability and repeatibility in performance. Furthermore, it adopts the differential signal transmission form, which is a high-level signal transmission and ensures the accuracy in transmission in a stronger way.

This type of encoder has a fast response time, and its working principle is actually very simple. It is composed of two parts, the first part is the sensing unit which consists of the self-generated magnetic field and a Hall effect sensor, and the second part is the conversion and transmission unit. The sensing module will generate a certain magnetic field with its self-generated winding or permanent magnet, and the Hall element will detect the change of the magnetic field. After the detection, the system will generate an analog voltage signal according to the magnetic field. This voltage signal can then be converted to a digital signal, and it can be transmitted as a signal pulses or other digital signals, from the conversion and transmission units.

The analog voltage signals generated by the sensing module varies with rotational speed, and the conversion and transmission module can then output corresponding electrical signals according to the analog voltage signals. In this way, the encoder will record the rotary displacement of the shaft, and it can also identify the direction of displacement and the speed information. Therefore, it can be used to control speed and count pulse, and this encoder can be widely applied in robots, robots, CNC machine tools, electrical machinery, printing machinery, paper and pulp machinery, and other automated products. The H20DB-37-SS-250-AB-15V/OC-SM16-S can be used in fields where high precision, high stability, and high speed are required.

The H20DB-37-SS-250-AB-15V/OC-SM16-S type encoders features a wide operating temperature range from -20°C to +100°C, can work in a wide range of voltage from 3 to 15V, and its repeatability can achieve a value as low as 0.1μm. It is also protected with a high waterproof and dustproof rating, which is ideal for use in harsh and extreme environment. It also has a real-time self-diagnosis, which can detect the fault in electronic circuits, and thus improve its accuracy and reliability. In conclusion, the H20DB-37-SS-250-AB-15V/OC-SM16-
