RF one-step BNC/TNC connectors
(cont’d.)
Part selection process
1. From Product Options and Dimensions on page 8-61, select the connector style you need
(BNC or TNC, plug or jack, male or female contacts).
2. From the tables that follow, find the appropriate table for the connector style you selected.
3. From the appropriate table, select the connector part number based on the RG cable type or Raychem cable part number.
For cable types not shown use the cable dimensions.
Note: The cable dimensions in each table are keyed to the diagram below.
