# Overview and Features

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

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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.md?ask=<question>&goal=<user_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.
