18-pulse per rotation rotary encoder, with "teeth" so you can feel the 18 steps as faint "clicks". Panel-mountable or you can put it in a breadboard (see accessories) when you simply cut or bend the two side tabs. This encoder also has a built-in push button so you can turn on/off a separate unit. One side has a 3 pin (ground and two coding pins) and the other side has two pins for a normally open contact.
Rotary encoders are useful as rotation sensors or selectors. They look like potentiometers, but they are not exactly the same as potentiometers, and it is important to know the difference! Rotary encoders can be rotated infinitely and are divided into a number of steps/segments (this one in 18). Each step has a mechanical "clicking" feel, thanks to the "teeth" built into the dial. There is no way to know the current position - When rotating, each segment click simply causes a switch to open and close. A connected microcontroller (for example an Arduino Uno) can thus count how many left and right clicks are made. If instead you need to detect rotational 'position' then a potentiometer is a better choice.
