What are the parameters of the model selection of the rotary encoder products? Automation technology release date: 2019 - 8 - Browse 7 750 times the speed of the rotary encoder is integrating opto-mechatronics technologies displacement sensor. When rotary encoder shaft drives the rotating grating, light emitted by the luminous element is slit grating plate cutting into intermittent light, and by generating the initial signal receiving components. Is characterized by small volume, light weight, many varieties, full functions, high frequency response, high resolution, small torque, low consumption, stable performance, reliable service life is long, etc. Encoder to introduce what are the parameters of the model selection of the rotary encoder products? In the process of using a rotary encoder, the outstanding performance depends on the center of the encoder. , have different scribed line above, starting from the Angle of use, the rotating disc is divided into four parts, including A/B/C/D four parts, just the difference between each part is 90 degrees, when the signal began to accept the corresponding sine signal through the corresponding Angle difference between different signal will make the necessary reverse and increase the performance of flexible each output signal, in the process, the corresponding zero reference appears very important. At the time of selection or procurement rotary encoder, need considering from various aspects, especially on the technical parameters of the need for a technical parameters on the reference: 1, the rotary encoder is in line with their own processing requirements and quality requirements; Rotary encoder system sort is more, to choose the suitable system; Due to the drive unit is the key to the rotary encoder control, when choosing drive unit, according to the precision of the workpieces to choose the appropriate drive unit. 2, performance: the performance of the rotary encoder mainly reflected on the equipment data processing and its material, considering the different use of the environment, for the encoder on the quality, wear resistance, corrosion resistence have more strict requirements. Encoder data processing ability is according to equipment considering internal chip data processing capabilities, usually, the higher the frequency of the processor, the better. 3, price: the price is also a vital factor, purchase to cost-effective products, of course, each user is the most ideal idea. While selecting a rotary encoder to choose prices consistent with equipment performance and consistent with the product for their own use, for similar products in the contrast, when choosing the encoder manufacturers also want to try to choose a large company, product quality and service quality more assured. 4, resolution: rotary encoder each lap of the output pulse number at work, whether using precision meet the design requirements. 5, installation size: including positioning check mouth, trunnion, mounting holes; Cable wire way; Installation space volume; Work environment protection grade whether meet the requirements. 6, electrical interface: rotary encoder output way has a push-pull output (common F type HTL format) The output voltage, ( E) , open collector ( C, C for common NPN output, C2 for PNP tube output) Long-term drive output. Its means of output should match the interface circuit of the control system. 7, space size: because of different environment, the choice of the size of rotary encoder is key, because the encoder connection between the internal parts, choose appropriate to the size of the code for the installation of machinery and equipment configuration has a good effect. For the shaft encoder and the user connection between the output shaft: should use elastic soft connection, avoid by all means use rigid connection, in order to avoid the user axis series, beating, causes the damage of shaft encoder and encoder. Encoder when installation should be gently push the bedding bag axis, it is forbidden to use hammers and break the collision, so as not to damage the shafting and encoder. Pay attention to the allowable axial load, shall not exceed the limit load. Should guarantee the encoder shaft and output shaft of the user in different speed < 0. 2 mm, with the axis of the Angle of < 2 °. For hollow shaft encoder, pay attention to the axial runout of encoder and the parameters of the radial runout whether the encoder to, be careful not to exceed its speed limit, such as more than allowed by the encoder limiting speed, the electrical signal may be lost, or bearing life shortened, use for a long time, please check the part connected to the encoder entity, and set screw is loose, affect the normal use of equipment in case, because the encoder is a precision instrument, should pay attention to when using the surrounding without source. Automation science and technology ( Shanghai) Co. , LTD. The main products are rotary encoder, photoelectric encoder, magnetoelectric encoder, composite encoder, bus encoder, absolute encoder, incremental encoder, miniature encoder, etc. On more than one: what are the differences between circle encoder and lap encoder? Next article: absolute value encoder application occasions have?
