Feedthrough components

Mounting instructions

To fully utilize their RF properties, the feedthrough components must be mounted directly into shiel­

ding walls. The case must be contacted seamlessly (sealed against RF signals) to the shielding

wall. This can be best done by screwing it into a threaded hole or bushing so that contact is made

via the threads.

Alternatively, the feedthrough components may be screwed into feed-through holes on the shielding

wall by means of attachment nuts. The contact between case and the shielding wall is then set up

via the contact surface of the thread.

Caution

Contacts with rigid copper busbars are not permitted in view of mechanical stresses of the

bushings due to impacts and vibrations.

For types with screw connections, the connecting cable must be secured between two nuts

to exclude a torque on the feedthrough pins. The use of two flat wrenches is recommended.
