# ODAC

ODAC is Zumbach's series of laser-based diameter measuring heads. They measure the diameter, ovality, and position of round products and profiles without contact. They are typically used in wire, cable, and hose extrusion as well as in plastics and rubber processing.

The number in the model name indicates the measuring field (the maximum measurable diameter) in millimeters. An **ODAC 34XY** therefore measures up to approx. 34 mm, an **ODAC 64XY** up to approx. 64 mm. The `XY` stands for dual-axis measurement.

## Supported protocols

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.enlyze.com/en/connect/ot-connectivity/supported-machine-manufacturers/zumbach/odac.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
