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 ...

Elma’s E18 rotary encoder comes in through-hole and surface-mount versions in the 14.4 x 11.4 x 6.5mm body size. Rotational life is up to 150,000 revolutions, according to distributor Foremost, which ...

Rotary encoders are pretty interesting pieces of technology. They’re a solid way to accurately measure rotation including the direction. [David] recently wrote some software to handle these input ...

A new hollow-shaft version of the company’s MCD rotary encoder makes it easy to mount the device on shafts up to 20 mm in diameter. A new hollow-shaft version of the company’s MCD rotary encoder makes ...

Melexis has announced the MLX90520, the new market reference inductive encoder IC with 22-bit resolution for rotary and linear movement. The IC fulfils the demand for high-accuracy, cost-effective ...

Adafruit has made an I2C interface for four rotary encoders. It comes in the form of a PCB with four footprints that accept one of the most common rotary encoder forms (Bournes PEC11 horizontal style) ...

Encoders are a vital component in many applications that require motion control and feedback information. Whether a system’s requirement is speed, direction, or distance, an encoder produces control ...

Now offered in standard inch shaft and coupling sizes, the T-Line 40-mm series of incremental rotary encoders are compact, 40-mm diameter (1.57 in.) encoders that come standard with an integral ...

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 ...

SCHAUMBURG, IL--(Marketwired - November 17, 2015) - HEIDENHAIN has released its new series of encoders for potentially explosive atmospheres (ATEX), which meet the new standards required today for ...

Experimenting with an HF oscillator, I needed to control the varactor diode voltage in precise increments over a 2V-10V range. A buffered potentiometer was the obvious choice, and connecting two pots ...

HEIDENHAIN has released its new series of encoders for potentially explosive atmospheres (ATEX), which meet the new standards required today for motion control applications. These HEIDENHAIN ExN and ...
