Feature: 1. [High Performance] Encoder adopts premium 385 DC motor, with good anti interference. The commutator thickens the carbon brush. The encoder circuit board already has a processing circuit. 2. [Input and Output] The input voltage of VCC is DC3 to 5 V. The output of phase A and phase B can be directly identified by the IO port of the single chip computer. 3. [90 Degree Phase Difference] The phase difference of AB encoder is 90 degree, and the lattice number is 96, that is, the motor rotates one circle, and 96 rectangular pulses are output by phase A and phase B respectively. 4. [Aluminum Alloy Shell] Premium aluminum alloy shell, not easy to corrode and rust, sturdy and firm. Excellent lubricating oil makes the friction force smaller and the motor starts more powerful. 5. [Brass Coil] Excellent brass coil, better conductivity, low power consumption and low noise, slow temperature rise, not easy to heat, supports long term use in various harsh environments.
