Backplane Connectors - Specialized: 51939-160LF Application Field and Working PrincipleBackplane connectors are specialized connectors designed for use in mechanical and electrical applications where a high density of contacts is required in a small space. The 51939-160LF is a backplane connector with a contact density of 160 positions, making it ideal for a variety of applications. In this article, we will discuss the application field and working principle of the 51939-160LF.The 51939-160LF is primarily used for backplane connections in the telecommunications industry, but they can also be used in other industries such as computing, automotive, automation, and more. The connector system is specifically designed for complex applications where a high density of contacts is needed. It has an integrated locking system that guarantees reliable mating and unmating, even in harsh environments. It is also designed to comply with IEC 60664-1 and UL 1977 standards.In terms of its physical characteristics, the 51939-160LF is made of a thermoplastic material that is resistant to vibration and shock. It is rated to operate up to 4500V AC, and it has an insulation resistance of 500MΩ. The contact layout is designed with two rows of 80 contacts in a 20x40mm grid, with an overall length of 41.2mm. The rated current of the contacts is 2.5A, and the rated temperature range is -40C to +120C.The 51939-160LF works by connecting two PCBs via two mating plugs. The contacts in the connector are connected to each other in different pathways, allowing the transference of signals and power across the two boards. This is accomplished via the insulated insulation sleeve, which comes in two types; a three-contact design, and a four contact design. The insulated insulation sleeve ensures that all contacts are properly isolated and protected from interference and accidental contact between other contacts.The 51939-160LF is easy to use and install, and requires no special tooling. It is pre-assembled for fast and cost-effective installation. Additionally, the connector is available with both male and female mating type plugs, to suit your specific application.In conclusion, the 51939-160LF backplane connector is an ideal choice for applications that require a high density of contacts in a small space. It has a reliable locking system, a high voltage rating of 4500V AC, and an insulation resistance of 500MΩ. Its rated temperature range is -40C to +120C, and its rated current is 2.5A. Furthermore, the connector is pre-assembled for quick and easy installation, with the option of male or female mating type plugs.
