Rectangular Cable Assemblies is a kind of wire harness which connects the electric and electronic components used for internal or external circuits. 45120-010030-3749/20-D-3 is an example of this kind of cable assembly which is widely used in various applications.In this article, we will take 45120-010030-3749/20-D-3 as an example. It is a three-way flat cable with a polarized connector. It is mainly used in aircraft, automobiles, buses, tractors, and heavy vehicles. This connector has an insulation rating of UL 94V-2 and a dielectric strength of 700V. Since this cable assembly is designed for use in higher temperature and vibration conditions, its high-grade insulation ensures the performance and reliability of the connection.The working principle of 45120-010030-3749/20-D-3 cable assembly is quite simple. Inside the cable, wires are arranged in three separate pairs. The wires in each pair are connected to each other through a polarized connector. The connector contains pins which are attached to the terminals and their contact is made through the resilient sleeves in the pin which helps to keep the connection insulated.45120-010030-3749/20-D-3 cable assembly is mainly used in applications which require a clean and reliable connection to test systems, direct current powers systems, electro-magnetic interference (EMI) and interference control systems, signal transmission systems, and multiple wiring systems. This type of cable is also used in medical, audio and video systems.This cable assembly has numerous advantages which make it suitable for different types of applications. It is designed to meet the requirements of UL 94V-2 standards, which ensure that the wires are properly insulated and can withstand higher temperatures and vibrations. Furthermore, the flat design of the cable allows easy installation and helps to reduce crosstalk. Moreover, the polarization makes it simple to identify and recognize the cables.In conclusion, 45120-010030-3749/20-D-3 is a three-way flat cable with a polarized connector. It is suitable for a variety of applications, including those that require a clean and reliable connection, such as test systems, direct current powers systems, electro-magnetic interference (EMI) and interference control systems, signal transmission systems, and multiple wiring systems. The high-grade insulation of the cable ensures the performance and reliability of the cable in different temperatures and vibration conditions.
