A rotary encoder, also called a shaft encoder, is an electro-mechanical device that converts the angular position or motion of a shaft or axle to analog or digital output signals. [1] There are two main types of rotary encoder: absolute and incremental. The output of an absolute encoder indicates the current shaft position, making it an angle ...

In 1987, a linear encoder series operating on the principle of light interference was introduced. It permitted measuring steps as fine as one nanometer . According to Heidenhain, in 2006 the company had regional sales locations in 43 countries and employed about 7,000 people, 2,600 of whom worked in the main facility in Traunreut, Germany.
Rotary incremental encoder with shaft attached to its thru-bore opening Introduction to incremental encoders, from VideoWiki script Incremental Encoder. An incremental encoder is a linear or rotary electromechanical device that has two output signals, A and B, which issue pulses when the device is moved. [1]
The company started as a car brake manufacturer after, in 1925, Albert H. Girling (also co-founder of Franks-Girling Universal Postage) patented a wedge-actuated braking system. In 1929 he sold the patent rights to the New Hudson company. Girling later developed disc brakes, which were successful on racing cars from the early 1950s to the 1970s ...
Other Dremel rotary tools include a cordless pumpkin carving tool, a cordless pet nail grooming tool, and a cordless golf cleaning tool. Approximate Dremel type spindle and collet/nut arrangement . The collets are flexible, and will accept both original Dremel and alternative makes of cutting, grinding, and polishing head shafts.
