Recommended Procedures for Coaxial Termination Type 734A Cable with BNC 90 Degree Plug Connector
**
This procedure provides the information to select cable, connectors, and the tools needed to terminate coaxial connectors on the coaxial cable at the customer location. This new product, when released, will use the same strippers, etc., as the BNC and TNC Straight Plug Connectors. COAXIAL CONNECTOR

Step 1
0.594 IN (15.09 MM)
Cut Type 734A Cable for BNC 90 Degree Plug Connectors to the proper length using the coax cutting tool.
0.344 IN (8.74 MM)
0.094 IN (2.4 MM) 0.156 IN (3.96 MM)
Step 2 Slide the crimp sleeve of the BNC connector onto the cable, placing it in a location at least 6 inches (15.3 cm) from the end of the cable.

Follow stripper instruction sheet included with the stripping tool for adjusting cutting lengths of each element of the coaxial cable. The stripped cable should be as shown in the diagram.
MARKED END OF CRIMP SLEEVE AWAY FROM CABLE END
Coaxial cable from some suppliers may have an additional metallic shield under the braided shield. This additional shield shall be trimmed back to the same dimension as the outer braiding. (See diagram.)
4403-B
Step 4 Snip the center conductor so there is a measurement of 0.156 in. (3.9 mm).
4618-A
Step 5 Place the center contact over the center conductor and crimp in place with the specified crimping tool.
4619-A
Note: Be sure the flange on the center contact butts against the crimping die of the jaw. To test the crimp strength, pull on the center conductor. Step 6
4625-A
Slide the BNC connector over the dielectric and under the braid until it is fully seated against the dielectric. Step 7 Slide the crimp sleeve over the braid until it butts against the BNC (TNC) connector. The crimp sleeve should cover approximately 0.125 in. (3.2 mm) of the jacket. No excess shield should be exposed between the sleeve and the body.
4638-A
Step 8 Using the specified crimping tool, center the die over the ferrule and crimp in place. To test the crimp strength, exert a moderate pull on the cable to test the strength and seating of the crimp connection. Using company standard procedures, test for opens or shorts.
