June 8, 2021
SCHURTER waterproof IEC appliance inlet type 4761 paired with the rewireable cord connector type 4762 is ideal for use in challenging environments. This appliance coupler is perfect for use in both outdoor and indoor harsh environment equipment, including marine and medical. For exmaple, the appliance coupler is perfect for supplying power to medical equipment used in medical offices or hospitals and is ideally suited for portable devices with exposure to ingress of particles or liquids.
The push/pull locking system of the connector set provides a strong reliable connection that also features a break-away cable in the event of overdue stress. The blue shape and color of the pull-out mechanism indicates the pull-out direction. A clear catch click is heard upon the proper seated connection. The connector style is like the international standards of IEC and UL/CSA 60320, but is distinguished by a special arrangement of the contacts. This prevents interchange with conventional power cords. The design of the 4761/4762 coupler system ensures that maximum power can be applied safely, while also ensuring maximum IP protection and cord retention. The connector can be temporarily submerged in water and can be cleaned with high-pressure hot water cleaners. Both components are easy to wire. The inlet is available with solder or quick-connect terminals. The cord connector is equipped with conventional screw terminals, as commonly seen in rewireable connector designs.
The appliance couplers are available in black and white. The dual components, appliance inlet and cord connector, can be ordered as complete sets. The inlet and connector are also available as individual components for separate inventorying. Accessory covers are available for both plug parts, providing a waterproof protection IP69K in an unplugged state. These protective covers also offer protection against pollutants, which can potentially contaminate the contacts. Applications include electric charging stations, dispensing pumps and docking stations.
The waterproof appliance coupler set is VDE and UL/CSA approved according to IEC/UL 60320. The component level approvals simplify the process for the equipment manufacturer to obtain approval of their appliances. The rated current is according to IEC 10 A @ 250 VAC, according to UL/CSA 15 A @ 250 VAC. The maximum operating temperature is +120 °C. Quick connect terminal options for the inlet: 4.8 x 0.8 mm, 6.3 x 0.8 mm or solder.
