    High-precision wheel rotary encoder designed for measuring material length, movement speed, and angular position in various industrial and automation systems. This encoder operates based on an optical sensor principle, ensuring stable and accurate pulse generation even in high-speed applications. The wheel-type construction allows direct measurement of moving materials such as cables, textiles, films, paper, or metal strips. With a resolution of 300 pulses per revolution (300 PPR) and a push-pull signal output, the encoder can be easily integrated into PLCs, counters, automation systems, or microcontrollers.

    Functions

    Accurate length measurement – the wheel directly contacts the moving material and generates pulses corresponding precisely to the traveled distance

    Motion direction detection – A and B phases allow detection of movement direction, making the encoder suitable for various automation processes

    Zero reference signal – the Z phase provides a reference pulse used to determine the exact starting position

    Stable signal for automation systems – push-pull output ensures reliable operation with most PLCs, controllers, and industrial counters

    Real-time speed measurement – pulse frequency enables accurate calculation of linear or rotational speed
