PT (photo left) and PTN (right) potentiometers, as they will be known, have shaft-less or shaft-inclusive, and panel-mount or soldered through-hole PCB-mount options.
Other options are linear, logarithmic, or reverse logarithmic tapers, mechanical angles of 235, 265, or 280°, and 50, 150 or 200mW rating. Operation is over -10 to 70°C.
Electronics Weekly requested more information, and CUI’s Reid Hornberger replied within minutes:
The PT family currently has our PT01 series, which is our rotary potentiometers with a shaft.
The PTN family is our line of shaft-less potentiometers and it currently has three series: PTN06, PTN10, and PTN15. The number there indicates the diameter (6, 10 and 15mm).
Each series has a single overarching datasheet, and the datasheet has a part number key to describe how the part number changes based on the specifications.
