Tips: Precautions for Installing and Using Rotary Encoder.
1. Although the encoder itself will not lose the number of turns in the interference environment, it will cause interference to the data in the transmission process, so when there is a motor in the system or a strong electromagnetic interference environment, the encoder power supply should use an isolated power supply and external extension. It is best to use double-shielded cables and other measures for the communication line.
2. The outer shell of the encoder shell and shielded cable should be well grounded to prevent damage to the encoder circuit due to lightning strikes or high-voltage static electricity!
3. Except for the above zero-setting (yellow wire) allows grounding, any other signal wires of the encoder are forbidden to be short-circuited with each other. After power-on, avoid accidentally touching the signal wires, otherwise it may cause permanent damage to the
circuit!
Single turn rotary encoder with single turn, 14 bit absolute encoder with natural binary code encoded output, working voltage 5V/ 24V can be chosen, the shaft encoder with shaft diameter 6mm/ 8mm, blind hole 8mm are optional. The absolute rotary encoder is used in computer input devices such as optomechanical mice and trackballs, controlled stress rheometers, and rotating radar platforms.
