Features Type: rotary encoder code with switch; adjustment method: 360 degree rotation; this rotary encoder is made of high quality material, corrosion-resistant, wear-resistant and durable. Sensitive response, stable performance, long service life. Simple structure, easy to install and use. In forward rotation, the phase of the A-line leads to the phase of the B-line, when vice versa, the phase of the B line leads to the phase of the A-line. The AB phase relationship and number of revolutions can be determined with a simple digital logic circuit (Exclusive OR Gate and D-Flip-Flop). According to the time diagram it is not strictly summarised, like the oblique edge of the shot, A and B are the reverse phase, is a forward rotation, and the same phase is inverted. Applications: industrial controls, robotics, photographic lenses, computer input devices such as optical mice and trackballs, controlled voltage rheometers and rotating radar platforms. Specification: Rated voltage: DC 5V Rotation Angle: 360 degrees (no stop point) Rotation Life: 30000+200 Cycles Contact Resistance: ≤100mΩ Insulation Resistance: ≥100MΩ Oscillation: ≤10mS pressing Operating Temperature: -30~80°C Storage Temperature: -40~85°C   Package List: 10 x Rotary Encoder 10 x Nuts 10 x Washers Package List
