Schoeps uses a fair bit of custom plastic to anchor the cable. Using the nanocon solves a lot of the engineering and manufacturing issues. It is an inexpensive off the shelf part for one of the trickiest bits, keeping the cost down. That part can be standardized across different capsule colettes. I like it.
It'd be kind of neat to solder extension pins into the nanocon solder cups, and then have those protrude through the pcb (or maybe just sit in cups on the underside). Though if they directly coupled to the pcb, cable strain on the pins might fatigue the connections over time. So maybe that wouldn't work. Maybe if the pins were thin enough to flex, or allowed to float?
The downside of the nanocon is the length of the plug in connector beyond the colette. Looks like it adds 0.9", plus any strain relief boot. That will bring the overall to about 1.9", plus capsule. I'm guessing that's comparable to the Lemo schoeps, but it has been quite a while since I've measured.
The portion of a Schoeps KC5 that extends outside the capsule is 5/8", plus 1/4" of neck for mounting the colette and strain relief. So about 7/8, or 22mm, overall. In some tight installations, that will be a challenge. Who will be the first to make a "stubbie nanocon", potted in epoxy, possibly with a right angle exit?
