The Han-Modular® series is a new system of inserts designed to meet the specific requirements of individual customers. In close cooperation with potential users, a range of modular inserts have been developed allowing the simple assembly of custom designed connectors which meet the diverse requirements encountered by designers today. Han-Modular® is a logical development of the Han-Com® series which already offers the combination of power and signal circuits in one connector. The individual modules of this versatile series now allow the integration of electrical, optical and gaseous signal and power connections in one connector assembly. The pneumatic contacts are also suitable for the connection of liquid media.
