Dual sensor for rotary actuators,DSU35

Functional principle

Inductive sensors detect metal objects
contactless and wear-free. Dual sensors are
especially designed for position detection in
rotary actuators. They combine the reliability
of non-contact inductive sensors with the
flexibility of a modular housing system.
