New connectors from Binder are IP67 unmated

BUK 055 Series 770, NCC ConnectorA new connector system from Binder has a design that protects the contacts to IP67 when not connected without the need of a protective cap.  Originally designed for medical equipment, the Binder 770 Series NCC (non-connected closed) range will also prove ideal for all types of portable or hand-held measuring equipment, control devices and other applications where it is an advantage to make rapid set-up changes.  The efficiency of the design achieves a product life in excess of 5,000 mating cycles.

Series 770 is a panel-mount receptacle in which the electrical contacts are protected from water, dust and foreign particles by a spring-mounted lid when unmated. When the cable plug is mated the contact cover is pushed inside the receptacle body, the contacts engage and the connector is locked with a quarter turn of a bayonet-locking collar.  The connectors have eight gold-plated contacts, are rated to 2A and 175V in solder and dip-solder versions and cater for cable sizes from 2.5mm to 8mm diameter.
