Auxiliary mechanical devices: commonly used are rack and pinion, chain belt, friction runner, rope reeling machinery, etc.
Low-speed end device: device after the reduction gear, such as the shaft end of the winch wire rope drum or the shaft end of the next section of the reduction gear, this method has no gear back and forth clearance, the measurement is more direct, the accuracy is higher, this method generally measures long-distance positioning, such as various lifting equipment, feeding trolley positioning, etc.
High-speed end device: device at the power motor shaft end (or gear connection), the advantage of this method is high resolution, because the multi-turn encoder has 4096 circles, the number of motor rolling turns in this range range, can fully use the full range to improve the resolution, the disadvantage is that after the moving object passes through the reduction gear, there is a gear gap error in the round-trip trip, which is generally used for one-way high-precision control and positioning, such as the roll gap control of rolling steel. In addition, the encoder is directly installed at the high-speed end, and the motor jitter must be small, otherwise the encoder will be easily damaged.

A little bit about photoelectric sensors – a blessing
Under normal circumstances, a photoelectric sensor consists of two parts: a processing path and a processing element. Its basic principle is to use the photoelectric effect to convert the measured change into a change in the optical signal, and then use the optoelectronic components to further convert the non-electrical signal into an electrical signal. The "photoelectric effect" refers to the use of light ...

A brief introduction to our sensors
Proximity sensors are a general term for sensors that replace contact detection methods such as limit switches and do not require contact detection of the detected object. It is capable of converting information about the motion and presence of objects into electrical signals. The detection method of replacing the electrical signal includes: using an electromagnetic induction bow to ...
