I'm sure that as small as that difference seems, it would make a world of difference to the problems of connectors just disconnecting on their own, even without all the other workarounds, because it is almost double the amount of force required by the contacts we all are likely using right now.
(I did a few searches to see if this info is on ES, but did not find it by any of the search terms I could think of, including the p/n's.)
I have been doing a little searching to find the right part numbers to get a quote from Avnet on some various parts that they don't list in their online catalog, but I'm sure they can get if they tried. (Avnet because I have a free shipping coupon, and what I'm after is all so small that shipping costs would be negligible if things were normal, but we all know that shipping tends to be $12-$30 for a packet of stuff that'd fit in a padded envelope for a couple bucks if they'd just do it that way. )
Anyhow, in that search, I started reading the Anderson Power Products site and specifications. In doing so I found the notes about the different pull-apart-force contacts for these.
Now, I don't have an individual contact p/n for the High-Detent force 45A contacts, as they seem to have accidentally left that off the datasheet. I know one exists because there is one for the LD-force individuals, and there is a full reel p/n for them. I list below what I *think* the p/n is, with an * since it might be wrong.
Datasheets are all on their Anderson Power Pole pages:

Contact p/n's for the PP45 series:

Under No Load (no power applied) mating cycles= 10,000
Under Load (with 120V applied) mating cycles=250, at 15A to 75A (depending on which kind of contacts you have installed)
The 45A contacts use a 30A load for that test.
Contact retention force (how hard you have to pull on the wire to yank it out of the housing):
(lbf) 25 to 170
(N) 111 to 756
Contact detent force (how hard you have to pull two connectors to separate them):
(lbf) 3 to 20
(N) 14 to 89
(depends on which contacts for each size)
(Â°C) -20Â° to 105Â°
(Â°F) -4Â° to 221Â°
(they can make higher-temperature-rated ones, apparently, not sure why not lower-temperatures)
They are all rated for up to 600VDC or VAC.
I am going to try to get the higher detent force contacts via Avnet to see if there's much of a difference. I can definitely say that the few I have here already on some things I've gotten from various ES members don't take much to pull them apart. I do not know but do believe that they are all likely the low-force contacts. In some cases, just the weight of very heavy gauge wire could be expected to disconnect them, under shock loads from road bumps and potholes, depending on how many plugs are bound together in a block.
