Introduction: The 71991-840 rectangular connectors are an important part of the electronics industry. These connectors are typically used in a variety of applications such as control and power supply systems. They are available in both headers and receptacles, and also come in female sockets. The 71991-840 connectors are typically designed with shield and covering around them to ensure safety and provide better durability.

Application Field: The 71991-840 rectangular connectors are primarily used in the electrical and electronic industries. They are often used to interconnect PCBs, terminals, and devices that need to be linked in order to operate. These connectors provide reliable electrical and/or mechanical connections. The connectors are not only used in power supplies and control systems, they are also used in industrial, medical, and automotive applications.

Construction and Materials: These connectors are typically constructed from machined zinc alloy or copper alloy material, depending on the specific requirements. The material used for the construction provides good durability and strength. The connectors also have a gold plating over the contacts which provides better conductivity. There is an insulator used between the pins and the contacts which helps to protect the device from any kind of damage. The connectors are also designed with a unique combination of shape, dimensions, and size in order to provide a secure fitting into most standard applications.

Specifications: The connectors have a rated voltage of 50V AC/DC at a frequency of 400Hz. Additionally, these connectors can handle a temperature range of -55°C to +125°C. Moreover, the connectors have an operation current rating of up to 8 amperes and a contact resistance of 10 milli-ohms. The connectors also feature a range of specs such as an insulating resistance of 1000 mega-ohms and a dielectric strength of 500 V RMS.

Working Principle: The working principle of the 71991-840 rectangular connectors is based on the flow of electricity between the two connected components. When the contact present on the connectors is mated, the connection is completed, which allows the electricity to flow from one component to another. The electricity then passes through the contacts and connects the components together, allowing them to function accordingly. Additionally, these connectors also feature a shielding system which prevents any interference or noise from affecting the current. This helps to ensure a more consistent and reliable performance from the device.

Conclusion: The 71991-840 rectangular connectors are an invaluable tool for connecting components in the electronic and electrical industries. They provide reliable and secure connections that are capable of handling a wide range of conditions. Additionally, they offer an increased level of protection from external interference. These connectors are extremely useful in a number of applications and are commonly utilized in control and power systems.
