The ES25 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 isolates the encoder from
external equipment, protecting it from high shock, vibration and
environmental debris. Since the ES25 is not physically coupled to
external equipment, the problem of shaft misalignment is
eliminated, meaning no more broken couplings!
The ES25 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.
