## Specifications
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](/welcome/electronics/miniature-linear-servo-actuators/general-info/general-data.md)). 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.
## Wiring
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.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://docs.wcproducts.com/welcome/electronics/miniature-linear-servo-actuators/overview-and-features/general-specs.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
