The ES20 is a rugged incremental encoder that is environmentally
sealed through the use of a magnetic shaft coupling connection.
This connection allows the encoder to be completely enclosed
and sealed against water ingress. It is rated to IP67 and can
operate while fully immersed in one meter of water for up to 30
minutes. The magnetic coupling also allows the encoder to be
isolated from high shock and vibration, dust tight, and resistant to
debris in the environment. Since the ES20 is not physically
coupled to external equipment, the problem of shaft misalignment
is eliminated, meaning no more broken couplings!
The ES20 is ideal for applications with heavy wash-downs,
temporary water immersions, and excessive environmental
debris. It combines the high accuracy, repeatability and
robustness needed for use in harsh environments and can help
reduce costly downtime of your system.
