Bulkhead Feed-Through
PENN ENGINEERING’S Bulkhead Feed-Throughs will assist when a waveguide system must pass through a pressurized wall or cabinet. A heavy mounting flange and a gasket provide secure sealing. Brass units are Silver plated per QQ-S-365D Class A, Aluminum units are Chem-film per MIL-C-5541E, and both are finished with PENN ENGINEERING’S Metallic Blue Paint.
Special Bulkheads are available upon request.
