If this is for production access only, then here's a trick I used once. The PCB (standard 0.062" thickness) was designed with SMT pads along one edge (both sides) so that a 2×7 0.100" JTAG header could be soldered to it, with the pins sticking out from the edge. This was useful for debugging prototypes, which needed more or less constant access to the JTAG (and weren't in cases).
In production, the connector is omitted, and I used a slightly modified DIP clip to access the pads for the connector. I just needed to bend the contacts inward a bit to get adequate friction and contact pressure.
Instead of the DIP clip, you could use a standard card edge connector as well.
[This started as a comment, but I've run out of room. Systems engineering is wordy work.]
I've tried to look up the draft standard mentioned in the comments, but to almost no avail. The website 1Wire.org seems to be defunct. The best pinout information is on pp.13-14 of the 1-Wire Application Guide 1.03, which David (the O.P.) have dug up.
David, I understand your question, but I don't understand your problem. Please correct me if I'm wrong with the following.
- Are you planning to use an existing 1-wire host box?
Looks like you don't. If you did, you would be forced to conform to the pinout of that hypothetical box.
- Are you planning to use an existing sensor with a connector?
Again, it looks like you don't. If you did, the sensor would force the pinout on you. So far, you have been mentioning sensors packaged in TO-92.
- Are you planning to sell your the sensor assemblies to the 3rd parties, so that they can use it with host boxes that are already out there?
The RJ-11 cable is the thinnest, cheapest (between Between RJ-11, RJ-12 and RJ-45). For a relatively closed system whose components don't interface with 3rd party components, I would pick a common RJ-11 pinout from the table on p.13 and use that.

It's a proprietary Samsung connector. Referred to as the Samsung 20-Pin Connector, or S20-Pin connector. It is used for multiple connections, including Audio, Headsets, USB, Serial and Charging.
