HOW TO SELECT A BACKSHELL
1. Select the Backshell Type, pg. 6-7
(i.e. Non-Environmental backshell)
2. Select Angle, pg. 8
(i.e. Straight)
3. Select Coupling Style, pg. 8
(i.e. Spin)
In order to complete steps 4-9, you must know the connector specification. For example, we’ll use connector D38999/26WB35PN
to walk through the remaining steps of selecting a backshell.
4. Select Connector Group Code based on your connector specification, pg. 9-13
(i.e. L)
5. Go to Table of Contents, pg. 4, to find the page numbers your selection resides
(i.e. page 56-58)
6. For the material and finish options, review Table-2 on pg. 14
(i.e. Cadmium Olive Drab over Electroless Nickel)
*Recommended to follow the same finish as connector
In order to complete step 7, you must know the actual cable diameter. For example, we’ll use the cable diameter of 0.20 inches to
walk through the remaining steps of selecting a backshell.
7. Determine the clamp size by using the table on the product page.
(i.e. page 56)
For this example a 0.20 in cable diameter
will be used.
(i.e. Clamp size-02)
*Omit if not available in the backshell selected
8. If applicable, determine backshell length using the table on the product page.
(i.e. page 56; 2.53 = A)
*Omit if not available in the backshell selected/ Skip for 90
o

9. Build a part number based on the selections you made
(i.e. M85049/2111W02A)
