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.
