The MA3 from US Digital is a miniature absolute magnetic shaft encoder that provides shaft position information over 360° of rotation with no stops or gaps. The device is available in two output ...

This Design Idea combines a simple ISA-bus-resident interface circuit; a garden-variety PC; a high-resolution optical shaft encoder; and a PWM-controlled, 0.05-hp, brushed, permanent-magnet dc motor ...

Vying for position as a contactless alternative to mechanical rotary switches, the AS5030 and AS5130 8-bit absolute magnetic rotary encoders integrate push button and low-power mode features. Both ...

I want to write about something a little different this time. I removed the mechanical scroll wheel rotary encoder from a discarded optical mouse and used it in a little project. I really liked the ...
