Data Sheet ME22S-PU www.pwb-encoders.com precision works better Description The ME22S is a reliable optical shaft encoder. It is suitable as a potentiometer substitute. The ME22S can be fixed quickly and easily. The encoder provides two square wave outputs in quadrature (90 degrees phase shifted) for counting and direction information and one optional index channel (one pulse per revolution). The resolution of the encoder is determined by the number of counts per revolution (CPR). Power supply and signals are provided by a 5 pin Molex connector. Features Small size: 22.0 mm diameter x 15.8 mm length. Output channels: 2 (quadrature) + 1 optional index-channel Power supply: 5 VDC Output type: TTL compatible Output circuit: pull-up Resolution up to 360 CPR (counts per revolution) Operating temperature: -20 °C to 85 °C Frequency: 60 kHz Compliant EU-directive 2011/65/EU (RoHS) PWB encoders GmbH Am Goldberg 2 D-99817 Eisenach Germany info@pwb-encoders.com / www.pwb-encoders.com

Data Sheet ME22S-PU www.pwb-encoders.com precision works better Electrical interface Encoding characteristics channel A & B Parameter Pulse width Phase shift Definitions Counts per Revolution (CPR): The number of bar and window pairs or increments per revolution of the code wheel. One Cycle (C): 360 electrical degrees (°e), one period of the signal, caused by one pair of bar and window. Pulse Width (P): The number of electrical degrees that an output is high during one cycle. This value is nominally 180 ºe. State Width (S): The number of electrical degrees between a transition in the output...
