RI41-O/1024AR.11TX-F0-S is an encoder made by Hengstler. Here is a datasheet that should provide a point of reference to compare the alternates I will list. Here are the main specifications according to the part number breakdown:
Number of Pulses
The number of pulses should be 1024. This is a typical value that lines up with other kinds of encoders.
Supply Voltage
The supply voltage is 5V.
Shaft Details
The shaft is called a “pilot shaft”, is rated at IP40 for ingress protection, and is 6mm in diameter.
Output
While this encoder may be customized for this, the closest alternative is to just use a push-pull configuration.
The other details in this particular part number are not explained according to the datasheet. Please review these alternates for your own application with careful attention to detail.
