The RK series is a high-performance, low-cost optical 2-channel incremental encoder module for wide voltage range operation.
It consists of a highly collimated light source and a detector IC enclosed in a small C-shaped plastic package, matched with a code-wheel or code-strip, it provides information of rotary or linear position.
The RK Series has linear ( LPI ) options: 20, 37, 45, 75, 90, 120, 150, 180, 254, 300, 360, 450.
Typical applications include: Printers, Plotters, Servo motors, DC motors, Office automation etc.
Safety Notice: Not recommended for use in safety critical application. Eg. ABS braking system.
