Tips: What is Rotary Encoder?
This is a detector that can output angle data within one revolution of the motor to an external target. Absolute encoders are generally capable of outputting 360° with 8 to 12 bits. Incremental encoders have the disadvantage of losing axis position in the event of a power failure. However, with absolute encoders, the axis position is not lost even in the event of a power failure. Various codes such as binary code and BCD code can be output. Absolute encoders are more expensive, more precise and larger than incremental encoders.
Cheap rotary encoder for sales online. Single turn absolute encoder with 10 bit, RS485/ CAN/ SSI three communication interfaces for selection, working voltage 5V/ 24V are available, absolute rotary encoder with 50mA/ 100mA working current. The shaft encoder is widely used inmachine tools, food machinery, elevators and other special equipment.
