This version adds a ground wire giving the user the option to electrically ground the USB female connector to their panel or enclosure. The #6 spade lug easily attaches to a screw or similar hardware. These USB 2.0 panel mount cables are perfect for use inside a box or enclosure. The USB Type A female side is flange-style panel mountable with an alternative, smaller body compared to the popular ECF504 series. This makes it a nice fit in applications with limited space. The molded panel mountable USB construction is rugged and robust, using 20 AWG power conductors and a 28 AWG twisted pair all under a double shield for maximum EMI resistance. Each assembly includes two 4-40 x 3/8" Phillips pan head mounting screws.
