Note
For hygienic applications (3A & EHEDG) the cable glands and blind plugs must be made
from corrosion resistant material like nickel brass, stainless steel or plastic. The exposed
threads must be minimized when they are tightened up on the cable and they must have a
seal (plastic or rubber) under the threads where they screw into the terminal housing or
enclosure.
