Explanation:

Series

ETL - MIL connector terminal interface modules; this breakdown covers ETL-20, ETL-20K, ETL-34, ETL-34K, ETL-40 and ETL-40K only.

Connector Contacts

20 - 20 contacts
34 - 34 contacts
40 - 40 contacts

Terminal Numbering

Blank - Omit this field; consecutive rows 1–10 and 11–20 for 20 contacts, 1–17 and 18–34 for 34 contacts, or 1–20 and 21–40 for 40 contacts
K - Odd numbers in one row and even numbers in the other: 1–19/2–20, 1–33/2–34 or 1–39/2–40 for the respective contact counts

Description

MIL signal connector interfaces

ETL modules bring a MIL connector to field-wiring terminals in three contact counts. Standard models number each terminal row consecutively; K models use odd and even terminal numbering. Match the numbering layout and cable assignment to the equipment connection.
