Option 1: Crimped Strain relief
Cable rotation can lead to breakage of the individual wires in the cable. This can lead to intermittent system errors
which are typically very difficult to find.
The Solution: Crimping the cable jacket
Advantage: A well defined and proven method. The crimp insert protects the
con-ductors against damage during the crimping process. Creating unparelleled
EMI shielding all around the connector.
Fits both Standard and
Quick Lock hoods.

How to select the correct crimp flange
Step
1
Description
Example
Measure the outside cable diameter (3 times on different places at different angles)
OD = 6.5mm
2
Strip the cable and remove the cable braiding
3
4
Measure the diameter of the inner cable bundle including the foil
ID = 4.4mm
PN = 2-2308349-1,
ID = 4.5mm, OD = 5.5mm
Select the crimp flange with a hole diameter next up to the cable bundle diameter
Thickness cable jacket =
6.5 -4.4)/2 = 1.05mm
Barrel ID = 5.5mm + 2x 1.05
+ 0.2mm = 7.8mm
Calculate the recommended barrel inner diameter with the following formula:
5
Recommended Inner crimp barrel diameter = OD of crimp flange + 2x(thickness of the
cable jacket) + 0.2mm
PN = 1-2308350-7,
ID = 8.0mm, OD = 9.0mm

Select the crimp barrel with the next size up
PN = 1-2823557-1 &
1-2823558-3
Order the correct crimp tool & crimp insert using the crimp barrel selection matrix
Prepare a cable sample and check if the pull out force meets your requirements.
