Addressing USB connectivity application requirements in environments prone to vibration and cable pull, ECF-style USB couplers employ high-retention connectors that offer mating force of 40N max and un-mating force of 15N min. Available connector configurations include USB Type B-A, A-A, and A-B, and shielded housings limit effects of EMI/RFI found in industrial environments. Panel-mount style allows use in enclosures, panels, and other designs where feed-through USB coupler is required.
