Tips: Precautions for Installing and Using Rotary Encoder.
1. The encoder is a precision instrument. Please handle it with care and use it carefully, especially for the encoder shaft, please do not knock, hit or pull hard. Flexible connectors or elastic supports should be used for the connection between the encoder and the machine, and the rigid damage caused by the non-concentricity of the rigid connection should be avoided.
2. Although the encoder housing is waterproof (IP54), the protection level of the shaft is IP65. Avoid installing the shaft upward or immersing in water, otherwise use a waterproof cover or other measures.
High resolution rotary encoder with single turn, shaft encoder has RS485/ CAN/ SSI three communication interfaces for selection, with shaft diameter 6mm/ 8mm, blind hole 8mm are optional. The 12 bit absolute encoder offers high quality, high resolution and optional installation advantages.
