These nifty little linear servos act like pneumatic air cylinders, but are powered by an electronic servo instead of compressed air! This means that not only do they provide reliable linear motion, but also have the added bonus of being able to extend to any position in its range of motion, not just full in or full out!
These are self contained linear motion devices with position feedback for sophisticated position control capabilities, end of stroke limit switches for simple two position automation, or RC servo. Several gear ratios are available to give you varied speed/force configurations.
Notable Features
Available in 50, 100, and 140 mm stroke lengths
35:1, 63:1, and 150:1 gear ratios
Servo powered actuator does not take up a PDP slot
Mounts like a pneumatic air cylinder
The L16 is designed to push or pull a load along its full stroke length. The speed of travel is determined by the load applied. (See the Load Curves). Actuator speed can be reduced by lowering the drive voltage. When power is removed the actuator will hold its position, unless the applied load exceeds the back drive force. Repeated stalling or stalling for more than a few seconds will shorten the life of the actuator significantly. Stalling is when an actuator is pushing a load that it cannot move. Actuators should be tested in each specific application to determine their effective life under those loading conditions and environment.
1 - White – RC input signal (RC-servo compatible)
2 - Red – Power (+6 VDC)
3 - Black – Ground
Note: Reversing the polarity of pins 2 and 3 may permanently damage the actuator -R actuators are ideally suited to use in robotics and radio control models. The –R actuators or ‘linear servos’ are a direct replacement for regular radio controlled hobby servos. The desired actuator position is input to the actuator on lead 1 as a positive 5 Volt pulse width signal. A 1.0 ms pulse commands the controller to fully retract the actuator, and a 2.0 ms pulse signals it to fully extend. If the motion of the actuator, or of other servos in your system, seems erratic, place a 1–4Ω resistor in series with the actuator’s red V+ lead wire. L16 –R Linear Servos are the only 6 volt models in the L16 range because they are designed to work with typical RC receivers and battery packs. Consequently they also are compatible with Arduino control boards, VEX Microcontrollers and many other similar boards designed for robotics.
