Lumberg has expanded its portfolio of DC power supply connectors: The 1614 21 panel-mounting coupling, supplemented by the matching power supply connector, is tailored to applications that require high pulling forces combined with high rated currents of up to 10 A for the extra-low voltage range. The standard for such power supply plugs is usually a current carrying capacity of up to 2 A. In addition, the built-in coupling in straight design for front mounting has a load-bearing capacity of up to 15 N pulling force, which also allows devices to be suspended. The contact carrier of the built-in coupling and plug is made of glass fiber-reinforced plastic and classified to UL94 V0, the contacts are made of nickel-plated brass. The 3-pole design of the coupling also enables the transmission of signal currents. The rated voltage is 20 V(DC) at 10 A, the insulation resistance is at least 100 MΩ.
