Crimping Anderson SB 175 Wire Contacts like DIN 46235 Compression Cable Lugs

- This is my take on how to crimp Anderson SB 175 wire contacts. Instead of soldering, I use a Hilti NUN 54-22 crimping tool with DIN 46235 compatible dies.
The sound of the original video was rather bad because of the wind, so I overdubbed it and added some more background information to it. Therefore, video and audio are not in sync.
First of all:
You stripped the insulation to far back. You should strip it a few millimeter longer than needed for the lug.
Second:
Start crimping at the contact end and not the wire end as the lugs elongate a few millimeter when being crimped.
On crimping with a hexagonal crimp tool:
About 10 years ago I reached out to Anderson with the question if hexagonal crimpers are allowed as they recommend a 4 point indent crimper themselves. This also because of several forums and videos on CZcams making hexagonal crimps with a decent result.
That lead to a visit of their sales representative Jurgen Mann. I showed him how I made the crimps and he took a few samples with him for testing.
Testing confirmed a correct crimp on the condition that I use the 35mm2 crimping die for all the wire sizes of the SB175. So for the 25mm2 cable in the 25mm2 lug, 35mm2 cable in the 35mm2 lug and even for the 50mm2 cable in the 50mm2 lug.
So it is possible to get a correct crimp on the SB175 with a hexagonal crimper. But they still not recommend it.
Hi @Richard1977, thanks for sharing this information. I will try that out.
Thanks sir! I may get into using these!
There was analysis for resistance between soldered and crimped Anderson connectors. The crimps had more resistance.
That sounds quite plausible. I never measured and compared that directly. Do you have any numbers on that or a link to such information?

Bad idea to have all that exposed copper even with shrink tubing on top. Less rigid and can give trouble. And the insulation helps with positioning the contact properly in the housing. Better to strip the insulation flush with the contact barrel end. Also, if your red marked wire is the +, as one would expect, you have the wires the wrong way around in the Anderson plug.
Hi @e9999qwe and thank you for your comment and sharing your experience with crimping Anderson connectors. For my installations the crimping even with the exposed copper proved not be a problem or causing trouble. I will try your method on the next crimp. Regarding the marking and "+" you are absolutely correct.
