Which connector for Rotary Encoder Nidec Copal RES20D-50-201-1?

Hi all,

I like to use the optical encoder RES20D-50-201-1 from Nidec Copal. See data sheet below:

DataSheet@NidecCopal

see page 3 outline dimensions, on page 4 the pitch for the non-leaded version is shown.

Note: Functional-wise the non-leaded versions are not prefered (need for additional electronics for signal shaping (sounds strange, but it is like this. (Option "D" (=square wave output) is not available for this variant, for those who like to understand), and even more expensive)

However, the information about the attached 4-lead AWG26 is quite vague, so I don't know at all what kind of connector-pair I can use to make the connection to my PCB.

So my question is what connector I have to attach to the cable, and what is a suitable receptacle to place on my PCB? Is this 4-stranded cable somehow a standard? If so, what are the parameters (e.g. pitch, this-type-of-connector-will-always-work, ...)
Or, does anybody of you can provide some key words so that I can search on mouser or similar? I even don't know the approbriate english name for that kind of that connector ... and they are by far too much of various type out there in the world.

Your support is highly appreciated.

Edit: I even may buy different versions with respect to pitch just to save shipping cost. But then I need some glue on what kind of connectors are typical for ribbon cables ...

That is a question I cannot properly answer. You point to an encoder datasheet (great) without any information on the application. The version with the wire leads has the option of probably several thousand types of connectors that can be used. It would be best if you narrowed it down. A lot depends on your local resources and what is available in your time line.

Well, I need a rotary encoder because its function is manifold (for adjusting various parameters) so that potentiometer is not an option (because full round is always matched to some parameter range, however, absolute position is given by respective value (which, well, varies). Parameters are time, color temperature (of an tunable white LED), brightness, ... and some more). Additionally, for some of those parameters resolution shall be high for one round (e.g. on brightness), so that I need a high resolution per round. With 50 in quad-evalution, i.e. 200 values, it fits to desired performance for some (not all!) of parameters to set (for sure not needed for setting the hours of the day of an internal clock, but, as said, for others). To my knowledge, mechanical encoders don't do that resolution (for manual input!), so optical encoder.
The one provided is one I can purchase.

Which is exactly my problem. In which sub-sub-sub-category I have to search? Believe me I'm trying quite a lot on mouser and farnell, but no success.
How are those connectors called one can find in a PC? I need single row, 4 pins - which are less connections than in a typical PC tower ... so I was either to stupid to find them, or they don't exist ...
