• 【General Parameters】Model: KY-040, Working Voltage: 5V, One round number of pulse: 20.
• 【No Limited Rotation Counts】The rotary encoder can count the number of pulse output during rotation in the positive direction and reverse direction through the rotation and this rotation counts are not limited.
• 【Encoder Key】With the key on the rotary encoder, you can reset to the initial state, that is, counting from 0.
• 【Application】Best choice for stepper and servo motor control. You could also use it to control devices like digital potentiometer.
• 【Package Included】5 x KY-040 360 Degree Rotary Encoder Module + 5 x Encoder Push Button
