Schaltbau’s DN series connectors are now watertight according to IP69K – when plugged and unplugged. This is true for both the metal and plastic versions. The connector has been tested under pressure of 80 up to 100 bar and at a water temperature of 18°C. This makes the connector especially suitable to withstand pressurised cleaning. It is also suitable for use in the foodstuff industry and for outdoor applications.
The DN family is available in two model series; the tough metal housing is made from nickel-plated die-cast zinc, and the plastic housing is made from durable plastic. The DN connector is structured on a modular basis, which means that housings are available for shrink boots, cable sleeves and braided screen connections. The bayonet coupling ensures fast, safe connections. Orientation is via bayonet latch positions in the housing. The mechanical working life of the metal variant is 5000 mating cycles, and that of the plastic version is around 1000. Both versions are available in each case with a different number of poles. The DN model series can be used at temperatures from -55°C to +85°C and complies with the requirements of standard IEC 60512.
The connectors are fitted with Schaltbau’s patented, self-cleaning spring contact system, and the spring-loaded contacts with self-cleaning faces are gilded. This gives a high level of resistance to shock and vibration. In addition, it ensures a low volume resistance for consistently high contact reliability even with low voltages and currents. The variable structure of the DN metal series also allows the use of screen attenuation and filter discs to prevent disturbance from external EMI factors.
