Okay, I've analyzed the provided text. It appears to be a section from a technical drawing or specification sheet, likely for a connector or similar component, specifically an "18 POSITION PLUG, SOCKET, AT SERIES" manufactured by SINE, a subsidiary of Amphenol Corporation.

Here's a breakdown of what the text describes:

1. General Information:

· Product: 18 Position Plug/Socket, AT Series
· Manufacturer: SINE (subsidiary of Amphenol Corporation)
· Document Type: Technical Drawing/Specification Sheet (provides design details)

2. Key Components/Configurations:

· Configurations: The document describes several configurations based on "KEY" designations: KEY-A, KEY-B, and KEY-C. These likely refer to different versions or variations of the plug/socket.
· Part Number Structure: The part numbers follow a pattern: `AT16-XX-XX`, where:
* `AT16`: Likely identifies the series and potentially other characteristics.
* The subsequent characters represent configuration options.
· Key Attributes: For each configuration, the document details:
* Part Number: The specific identifier for that variant.
* Strain Relief: Indicates whether strain relief is present ("NO" or "YES").
* Relief Color: Specifies the color of the strain relief, typically "BLACK," "GRAY," or "GREEN."

3. Data Table Format:

The data is presented in a table-like format, listing the part numbers and their associated attributes (strain relief and relief color) for each KEY designation.

4. Repeated Sections:
The content is repetitive.

5. Other Notes:

· The document notes that it is supplied "for information only," meaning it's likely not the complete set of documentation.
· It mentions "normal manufacturing variations," indicating that some tolerances are expected.
· "SEE P/N CHART" means that additional part numbers/information can be found on another chart.

Essentially, this excerpt is a detailed reference for identifying and understanding the different variations of a specific connector model.
