We use 38999 series 1 at work for lots of things but mostly for I/O panels on thermal vacuum chambers. Offers up to 61 pins and they are extremely robust which is good for connectors that are going to get a lot of mating cycles. We typically don't use them on the products since they are so large and heavy.
