D7/D12 Servo Series

    Looking for L12 series? Please see here.

    The 1st generation of mightyZAP actuator supporting precise position control / position feedback through communication without speed and current control features. IR Open protocol provided.

    D7/D12 Servo Series Features

    • Position control / Position feedback feature
    • Built-in drive circuit, position sensor, DC motor and gear box
    • Reasonable price compared to the 12Lf series
    • Stall force and speed adjustment within a limited range by adjusting the motor operating rate
    • 12mm diameter cored motor lineup
      (For better durability and force, see the 12Lf series)
    • 26mm stroke
    • Rated Load of 6N and 12N according to gear ratio
      (Speed ​​is inversely proportional to Rated Load, so the stronger the Rated Load, the slower the speed.)
    • Support RS-485 or TTL / PWM communication
      - TTL / PWM communication version operates by automatically recognizing the input TTL / PWM signal
      - When using PWM communication, only the position command is available without position feedback (For feedback feature, use TTL or RS-485 communication)
    • IR open protocol available.
      (The MODBUS RTU protocol is available with 12Lf series)
