7 Segment ( Cathode) 634 Omron Rotary Encoder (E6B2-CW6C) is

Omron Rotary Encoder (E6B2-CW6C) is an incremental encoder output a pulse string according to the rotational displacement of an axis

It can be set to blink or even breathe pins at varying rates

Three Digital/Analog Input/Output Rings

Tie Wrap is used to bunch cables in a neat bunch

7 Segment ( Cathode) 634 Omron Rotary Encoder (E6B2-CW6C) isIntroduction : 7 Segment common cathode display. All the cathodes of the LEDs in a 7 segment connected together and the common anode has all the anodes of the LEDs in a 7 segment connected together. In the common cathode display, all the cathode connections of the LED segments are connected together to 'logic 0' GND.
