12Lf Servo Series
Looking for L12 series? Please see here.
The 2nd Generation of mightyZAP actuators supporting position, current and speed control. Both MODBUS RTU & IR Open Protocols available

12Lf Servo Series Features
- The 2nd generation mightyZAP series supporting dynamic speed & current control as well as
position control along with position & current feedback - Built-in drive circuit, position sensor, 12mm diameter coreless DC motor and gear box
- 27/40/53/90mm stroke option
-
Rated Load of 12N ~ 100N according to gear ratio for each stroke
* 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)
-
Both MODBUS RTU and IR open protocols available
(Default : IR Open protocol)
