With the connectors of the 770 Series NCC (Not Connected Closed), Binder new products fulfill a protection degree of IP 67 even when the connection isn`t mated. With a little pride we now can offer a connector product family which fulfills the specified requirements and which avoids the disadvantages of the most common solutions on the market. As the abbreviation already implies the interface between the two halves is even closed when they are not mated. The special thing about this solution is hidden inside. At first sight one wouldn`t recognize that the the new product is an electrical connection as the typical contact elements of the panel mount part are covered by a spring mounted lid. This lid protects the contact area against water, dirt and foreign particles. Another important aspect is that the contact elements are touch proof and therefore are also protected against manipulation. The application field is wide and comprises all sectors but due to the special features this product is most suitable for measurement and control devices and especially the medical field.
