High Accuracy with Mini Encoders

Allerod, Denmark— Using the latest SMD and bonding technology, these miniature hollow shaft encoders are made with an outer diameter of only 24 mm, and are especially resistant to shock and vibration. They count 2,000 pulses per revolution and a maximum frequency of 200 kHz. Counting the leading and trailing edges of both channels provides four times the resolution, which means that the ...
