I have found that the Hirose (HR30) connector used with the G55/G58 doesn't create a very secure connection. If the connector is tugged straight on it will hold well, but if it is pulled at at an angle it pulls off very easily. Are there alternatives to this termination? Are there any plans to use something more rugged? Obviously the integral cable is an option, but on the G58 you cannot get both the integral cable and NEMA-4 sealing, the latter of which we require.

Thanks!

At this time we are not planning to use any other connector. The only options are the Hirose HR30 or an integral cable. We have spent a great amount of time looking for the connector on the G55/G58 but we were not able to find any other connector that would fit. There are many other circular connectors available but most are much larger than the Hirose HR30 and would not fit.

I talked to the design engineer for the G55/G58 and he told me that he was aware that the connector can come off when pulled to the side but that he could not find a better connector.

We have been using this connector for several years and most of our customers have no trouble with it. I asked my customer service department and they have not received any complaints about this connector coming off when pulled at an angle.

I tried two different cables on a G58 in my office. I found that one connector would not come off when I pressed on it at an angle but the other connector would. The connector that seemed to have trouble at an angle is on a very old cable and the connector has seen a lot of abuse (it was used for both G55 and G58 development and testing). I found that this particular connector, when used on my G58, that the locking ring would not always snap into place. The connector stayed on better when I pushed the locking ring up towards the G58.

I second that motion....

The hirose connector is not very secure nor is it very durable. Our main customer is the Navy Seals... believe me, they have no problem breaking these. A new option would be much appreciated.

I also have issue with the integral cable because of the loss of the NEMA rating as well.
