Rotary encoders are electromechanical devices used for sensing in myriad applications—on motors paired with drives and automated machinery for everything from consumer electronics, elevators, and ...

This article is part of the Ideas for Design Series: Vol. 3, No. 8. In many applications, accurately sensing the position of an electrically controlled mechanical device such as a motor is critical.

Rotary and linear optical encoders are common in position and motion sensing. Here, a disc or plate containing opaque and transparent segments passes between an LED and detector to interrupt a light ...

In any application using motors for automation, there is a need to ensure accurate control of the motor. To make this possible, the position and speed of the rotor in the motor, which is usually ...

The use of 100% hard-tooled parts and patented light-pipe technology for optical switching enables the Series 62AG optical encoder from Grayhill Inc. to be price-competitive with mechanical encoders ...

Avago Technologies, a leading supplier of analog interface components for communications, industrial and consumer applications, today announced a high-resolution absolute optical encoder for ...

This Design Idea utilizes an optical computer mouse's sensor for measuring rotation of a disk which can be mechanically connected to any sort of rotating apparatus. One feature is to allow adjustment ...

Continuing his tradition of making bits of wire and scraps of wood work wonders, [HomoFaciens] is back with a unique and clever design for an electromechanical encoder. There are lots of ways to build ...

PI, a global leader in precision motion control and air bearing motion systems, offers the A-688 rotary stage, a groundbreaking motorized, air-bearing based rotation stage, engineered for ...
