Noncontact magnetic rotary encoders are hard to beat when it comes to measuring rotary motion in machinery, as they are relatively small, strong, and inexpensive devices compared to traditional ...

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 ...

[Pete] needed a rotary encoder for one of his project so he set out to build his own. As the name implies, a rotary encoder measures rotation by encoding “steps” into electrical signals which can be ...

The RHI58 incremental rotary encoders offer pulse outputs up to 100,000 ppr. The hollow-shaft encoders provide a maximum frequency of 300 kHz with six outputs and a cable connection. Additional ...

SCHAUMBURG, IL--(Marketwired - January 18, 2017) - HEIDENHAIN introduces a new series of functionally safe hollow-shaft connection encoders to the manufacturing equipment industry. Called the ...

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) ...

Same Sky has created an absolute encoder family for motor shafts from 9 to 15.875mm (5/8inch). Called AMT25 and said to be accurate to ±0.2°, the family relies on the same in-house capacitive ASIC for ...

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 ...

These capacitive hollow shaft kit encoders are not limited to a single-turn measurement range: they feature an integrated rotation counter that records each revolution the instrument experiences, even ...

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 ...
