Baumer MA20

The Baumer MA20 is a high-precision incremental encoder with an optical measurement method, designed for industrial applications where high accuracy and reliability are required. This encoder uses a measuring wheel to ensure accurate rotation measurement, making it resistant to dust and vibration.

With a wide range of predefined resolutions, the MA20 allows for manual adjustment without the need for programming tools, making it user-friendly. Its robust construction ensures durability, featuring an aluminum housing and a measuring wheel with different degrees of rubber hardness for optimal grip.
