Optical encoders are electromechanical motion sensor and feedback devices comprising of a photodetector, LED light source, along with a disc with slot apertures. The benefits of optical encoders ...

Rotary encoders convert rotary movement or angular position into analogue or digital signals for use in measurement or control systems. They can be classified in a number of ways, primarily by the ...

Analog and digital optoelectronic sensors combine an LED and an optoelectronic integrated circuit in a compact package to enable optical encoders to provide absolute or incremental position detection ...

Alignment of optical encoder commutation signals to a Brushless DC (BLDC) motor could be thought of as being comparable to timing the distributor on a car engine. The distributor tells the spark plugs ...

The new QM22 series of incremental optical encoders from Quantum Devices Inc. measures just 22-mm in diameter and a 12.4-mm thick. It fits on a NEMA 11 BLDC servo motor and can replace the obsolete ...

Optical encoders are nothing new; they can be found in everything from mice to printers. They’re great for allowing DC motors to know their exact position and even current direction. If this is ...

Avago Technologies has designed a range of 3-channel optical incremental encoder modules for controlling DC servo motors, but also robotics and drones. The AEDT-981x module incorporates an ...

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

Aura P is a high-resolution absolute encoder in a super-compact form-factor. Credit INMOCO The Aura P is presented in a connection-ready PCBA (printed circuit board assembly), enabling fast and easy ...

Everyone has at least one extra mouse laying around; why not get some use out of it? Disassembling the mouse you can get two optical encoders plus four infrared emitter/detector pairs. Then you can ...
