If your corrector has got a male SC thread, it should fit without problems.
The "i" in UNFi stands for internal or female thread, and UNF is the thread standard. This thread may be better known as 2" SC-thread, as it is the standard thread used on the smaller Schmidt-Cassegrains.
If you need a male thread, there is also Baader 2"/2" Inverter Ring with 48mm filter thread # 1508020

Actually this focuser is made to use on a refractor telescope. The inner tube of this focuser has a diameter 63mm so please check if it can intrude
your OTA. A drawing of this focuser you can see here:
https://www.baader-planetarium.com/de/downloads/dl/file/id/28/product/2858/bds_rt_dimensions_technical_drawing.pdf
At the time we don´t have an adapter to direct mount the focuser to M117. Please contact your dealer from where you bought the OTA to find an
adapter - so far I can see several adapter are already available at TS.

Usually this focuser will be used with cassegrain type telescopes:

Unfortunately this was an error in the description which was discovered very recently actually and corrected in the specifications and german description. But apparently we forgot to change the english description. The description has now been updated with the following text, hopefully this clears it up. Sorry for the inconvenience! Here is the text:

Please Note: The Ultrashort clamp installed in this adapter #2458197 is not identical to the Ultrashort 2" Eyepiece clamp M68 / M60 (#2458196) which is available separately. The adapter #2458197 uses an older type of clamp #2458196, which can be recognized by the fact that it has only two knurled screws, while the individually available clamp has three screws. In contrast to the M60 thread of the #2458196 adapter, the older clamp used here has a ring dovetail on the telescopic side to accept the included 3.3" connection thread (T-2 component #18) (#2408145)

Unfortunately no - it has been standard for decades that a camera has got a female T-thread. Only recently, the first manufacturer has started to put male T-threads onto the cameras. At the moment, we don't have a female, camera-sided UFC-adapter.

You need a matching camera-sided adapter ("back plate") for the UFC; there are several options

The best would be
Baader UFC S52 dovetail camera-adapter #2459119
which fits directly to the Wide T-Ring, if you remove the T-2-inset from the Wide-T-Ring (there should be an Allen key included with the T-ring to do this). This gives you the widest free aperture and a permanent connection to the UFC, so it's probably the best if you attach the UFC to your telescope with a 2" nosepiece.

If you prefer a screw-coupling, you can also replace the T-2-inset of the Wide-T-ring with the optional
Reducing piece S52 / M48 # 2958552
and combine it with
Baader UFC M48 (m) Camera-Adapter # 2459116
This lets you use the full diameter of a 2" nosepiece or filter, and you can easily unscrew the camera from the filter holder

Otherwise, you can use the
Baader UFC T-2 (m) Camera-Adapter # 2459115
for a screw-coupling.
This is the standard solution as it was used for years, but you are limited to about 40mm of clear aperture because of the T-2-thread – so, if you use a full frame camera, there will be some vignetting at the edges. It's fine for APS-C and smaller sensors.
