XD-88 360' Encoder Description Arduino rotary encoder module KY-040  Operating voltage: 5V  Circle pulses: 20  Download Address: http: //www.kuaipan.cn/file/id_235696277512257652.htm  By rotating the rotary encoder can count forward and backward direction of rotation of the output pulse frequency during rotation count unlike potentiometers, this rotation count is not limited. With the button on the rotary encoder can be reset to the initial state, that is, from 0 to start counting.  How it works:  The incremental encoder is a rotational displacement signal is converted to a series of digital pulse rotary sensor. These pulses are used to control the angular displacement. In Eltra encoder angular displacement conversion using the photoelectric scanning principle. Reading system to rotate the radial indexing plate (code disk) consists of alternating opaque and translucent window windows constitute the basis, while the vertical irradiation is an infrared light source, an optical encoder of the image projected onto the surface of the receiver. The receiver is covered with a diffraction grating, which has the same width of the window the code wheel. The receiver's job is to feel the changes produced by rotating the disc, and then convert the light into corresponding electrical changes vary. Then make a low level signal rises to a higher level, and produce without any interference of square pulses, which must be processed by the electronic circuit. Reading systems typically employ a differential mode, the same waveform is about two different signals out of phase by 180 ° compared

Description These Hall-effect switches are monolithic integrated circuits with tighter magnetic specifications, designed to operate continuously over extended temperatures to +150° C, and are more stable with both temperature and supply voltage changes.  The uni-polar switching characteristic makes these devices ideal for use with a simple bar or rod magnet.  The four basic devices (, and ) are identical except for magnetic switch points. Each device includes a voltage regulator for operation with supply voltages of 4.5 to 24 volts, reverse battery protection diode, quadratic Hall-voltage generator, temperature compensation circuitry, small-signal amplifier, Schmitt trigger, and an open-collector output to sink up to 25 mA.  With suitable output pull up, they can be used with bipolar or CMOS logic circuits.  The A- and A- are improved replacements for the UGN/UGS-; the A- is the improved replacement for the UGN/UGS-.
