Yes, quadrature is technically a subset of Gray code, but "Gray code encoder" implies one Gray code cycle per rotation (i.e. usable for absolute position), IMO.<p>It's not a problem that this is a quadrature encoder—they're easier to interface with and adequate for most applications—but I would prefer a clearer description.</p><p>ETA: From the comments on the non-right-angle version of this encoder, I learned that it's actually 96 transitions per rotation. It's 24 full quadrature cycles per rotation; 1 quadrature cycle per detent. (I guess "24 pulses per rotation" could be considered correct, if you interpret "pulses" to mean either pulses of torque resistance, not electrical pulses, or electrical pulses on just one of the quadrature pins.)</p></p>

It now has a somewhat more permanent place in my (mostly empty) github repository; https://github.com/EagleWorks/eagle/blob/master/lbr/COM-10984.lbr . On that page, right-click 'Raw', and save the link :)</p>

And the two rows are 3.1mm apart.
So ignoring the 2 non-signal tabs, will the other pins fit on a bread board? Perhaps with a little bending?</p>

Here's a library with a single Device with the right angle package, based on SparkFun-Electromechanical.lbr/ENCODER_RGB_CA which only had the upright package. The only electrical difference is the addition of a NC pin connected to the two structural support pads, in case you want to do any grounding of them. The Document layer contains secondary package outlines. Please keep in mind that I don't have this part, and those dimensional drawings are conflicting, but the pad layout should be fine.
