NCC stands for Not Connected Closed, and when mated they meet the requirements of IP67 making them dust-tight and protected against temporary submersion, binder writes.
“The series is mainly designed for use in industrial and healthcare environments where liquid media typically occur. The connectors are equipped with an easy-to-use but reliable bayonet locking system that ensures quick and safe mating and unmating.”
Specifically, the 770 NCC series of 8-pin cable connectors with bayonet lock – in straight design – are equipped with moulded, UL-approved PUR or PVC cables, making field assembly unnecessary. They are offered with standard cable lengths of 2 m and 5 m; other lengths are available on request.
The cable cross-section is 8 x 0.25 mm² and the cable jacket diameter is 6.0 mm.
The bending radius of the cables in move is at least ten times the cable diameter, says binder, and at least five times the diameter for fixed cables. The maximum resistance of wire amounts to 79 Ω/km.
The overmoulded cable connectors are designed for a rated voltage of 175 V at a rated current of 2 A and withstand impulse voltages of up to 1750 V.
Their operating temperature range extends from -25 °C to +85 °C; the mechanical service life is specified at 5000 or more mating cycles.
The company outlines the challenges for medical engineering applications.
“On the one hand, smooth product surfaces are required for hygiene reasons. They prevent the accumulation of dirt and reduce the risk of contamination. On the other hand, in clinical applications, for example, mobile devices often have to be connected to others on site – in as little time as possible and without the risk of contaminating the unmated flange part of the connection.”
“Furthermore, medical device manufacturers demand a visually attractive design that fits seamlessly into the typical colour and shape schemes of this market segment.”
