Owner’s Manual
240898 Contact Element for Front Installation NC
- Large selection of different actuators
- Versions as an NC with positive opening, NO or disconnect terminal
Web Code 8082D
R. STAHL Series 8082 contact elements have an NO contact and a positive opening operation NC contact, made from silver- nickel or gold- plated. They can be easily combined with contact blocks and enable customized installations, also due to the large selection of the various actuators.
