Feature:1. The use of all metal materials makes it more wear resistant, rust proof and prolongs its service life. The copper wire has super electrical conductivity, which makes the motor output like water and high temperature resistance.2. The built in encoder measures the speed to ensure that a whole set of motors have the same speed and the same transmission speed. Two channel and three channel magnetic encoders with increased mile, suitable for any harsh environment.3. After the gear is ground, it is heat treated, which has the advantages of wear resistance, long life, and low noise. The protective cover protects the encoder and prevents it from becoming dusty and unusable after being used for a period of time.4. Each magnetic encoder contains a magnetic grid and a magnetic sensitive detection motor, and outputs two channels of squares waves with a quadrature phase angle of 90, and each motor has 16 pulse signals for each circle AB.5. This encoder gear motor is suitable for massage chairs, electric ovens, medical equipment, baby electric shakers, paper shredders, electric doors and window and industrial drives.Specification:Item Type: Encoder Metal GearmotorMaterial: Zinc Alloy, CopperOperating Voltage: DC 12VOutput Signal: Squares Waves AB PhaseOutput Shaft Size (Diameter x Length): Approx. 6x12mm / 0.2x0.5in Motor Diameter: Approx. 36.7mm/1.4inWhether To Measure Speed: Can Measure SpeedWhether Forward And Reverse: Can Be Forward and ReverseTemperature Range: -40~120Purpose: Industrial Drive Device.Package List:1 xMotorNote:1. Make sure that the voltage of the motor is correct before use. If it is a DC motor, confirm whether the power supply current is sufficient.2. It cannot be used with overload. The reason for overload is mainly divided into two parts: torsion and shaft force. The load torsion cannot exceed the rated torsion of the motor. The shaft force cannot exceed the axial and radial allowable force of the shaft. After the load is loaded, the measured current of the motor cannot exceed the rated current. Generally, the motor must be equipped with a fuse to avoid overloading the motor.
