Installation and use of hollow encoder

Hollow encoder is a kind of rotary encoder with free part in the middle for customers to add functions. Many customers use it in car products or power amplifiers, some kitchen appliances, medical equipment, etc. function rotation and key position applications. The hollow encoder has a good operating feel, and the hollow space can be added with a push switch to meet the needs of multi-functionality. Today we will discuss the installation method of the hollow encoder and the precautions for the operation of the hollow encoder.

Hollow encoder installation method

Generally, the hollow encoder is directly installed on the output shaft of the device. How to install the hollow encoder? First, install the shrapnel on the encoder and lock it with screws, and then let the locking ring of the encoder Unscrew the screw, and then gently push the encoder onto the output shaft of the coupling on the client. At this time, the output shaft of the client is stationary. At this time, the spindle of the encoder needs to rotate for two weeks. The purpose is Fix the shrapnel of the encoder on the mounting hole, and finally lock the locking ring of the encoder with the screw, and then the installation can be completed.

Precautions for the operation of hollow encoder

1. Regarding whether the resolution of the encoder is required by the equipment, it means that when the encoder is working, it will output a set of pulses per revolution to see if it meets the accuracy requirements of the equipment.

2. The common output methods of hollow encoder generally include push-pull output, open collector and voltage output. Then when using the encoder, you have to consider whether its output mode matches the interface circuit of the device's control system.

3. During the use of the encoder, pay attention to whether the connection between the encoder output shafts is flexibly connected. If there is looseness or bounce, the shaft disc of the encoder will be easily damaged.

4. When operating the encoder wiring, make sure that the wiring between the encoder and the device is not connected incorrectly, so as to avoid damage to the internal circuit of the encoder due to incorrect wiring during use.

5. When using the hollow encoder frequently, pay attention to checking the parts connected between the encoder and the device regularly, such as checking whether the fixing screws of the encoder are loose or whether there are any problems between the lines. In order to avoid some safety hazards and other accidents in the use of the encoder.

6. Since the inside of the hollow encoder is composed of some relatively high-precision components, it is necessary to prevent some water droplets or oil from splashing into the inside of the encoder during use, so as to prevent the components inside the encoder from contacting water droplets. , Causing some short-circuit and other faults.

7. Before installing the hollow encoder, first confirm whether the positioning stop on the equipment, installation space, installation space volume, installation hole position and other working environment protection meet the requirements.
