Cable Testers or Electronic Harness Testers Use Reed Relay Matrices
Introduction
An essential ingredient to any electronic system is its cable harness. These harnesses are made up of, in most cases, many individually coated copper wires routed to several different locations. Some of the individual lengths can cover several meters, while collectively, they may cover several kilometers. During the harnessing process, the wires can become scraped, kinked, knotted, and or partially severed. For electronic systems to have long reliably lives, making sure their cable harnesses have no flaws is essential. To verify the harnesses are flawless, cable testers are employed. Here the designers have chosen a matrix of high voltage reed relays to test each wire to all other wires using several 1000 volts.
