Coronavirus: Avoid Encoder Supply Chain Disruption – Find Replacements Quickly

March 16, 2020

The rapid spread of Coronavirus in China has been a cause of major supply chain disruption for many US manufacturers. For OEMs whose equipment uses incremental optical encoders to manage AC/DC motor speed, acceleration, and related equipment position, it has become a significant issue for overseas encoder manufacturers such as...

Very High-Resolution Application Solutions with QR12 and LP12 Sine/Cosine Incremental Encoder Output

February 14, 2020

Incremental rotary encoder resolution equals the number of measuring units in one revolution of the shaft, and is measured in PPR (pulses per revolution). Because incremental rotary encoders have A/B outputs, resolution is 4 times the PPR: accounting for 2 edges each on the A channel and B channel. High-resolution...
