Power source: DC5-24V Shaft: 6x13mm / 0.23x0.51" Size: 38x35.5mm / 1.49x1.39" Output: AB 2-phase output, rectangular orthogonal pulse circuit, NPN open collector output type Maximum mechanical speed: 5000 RPM Response frequency: 0-20kHz Cable length: 1.5 meters Note: AB 2-phase output must not be directly connected to VCC, as this may damage the output transistor. Terminal availability may vary by batch. Connection: Green = A phase White = B phase Red = Vcc power + Black = V0 Application: Used for measuring rotational speed, angle, acceleration, and length Suitable for intelligent control systems requiring displacement measurement, automatic length detection in leather cutting machines, steel cutting length control, height measurement devices, human scales, and student robotics projects Package included: 1 x Incremental Rotary Encoder
