Rectangular connectors like 851-91-031-20-001000 are one of the most commonly used types of connectors, suitable for applications ranging from automotive and industrial to consumer and PCBA markets. These rectangular-shaped connectors are the most versatile option in the industry as they come in numerous types to meet the needs of varied electrical connection requirements. They include a wide range of headers, receptacles, female sockets, and other related and genderless components.

Headers

Headers are rectangular-shaped connectors made up of a plastic housing and a number of contacts, normally 0.1" in centerline spacing and 0.062", 0.093", and 0.100" in thicknesses. They are designed for use with printed circuit boards, providing both input/output capabilities for electronic systems. It is also possible to have headers with vertical, right angle, and printed circuit board mountings and with optional screw terminations for mounting on breadboards. Other features like 2.54mm/2.00mm centerline and polarization ensure proper mating with PCBs.

Receptacles

Receptacles are basically connectors with a reversed version of the male socket onto which a female socket is mated. They usually have a rectangular mechanical body and different pin configurations and can be either surface mount, through hole, or right angle mounted to suit any design requirements. Typical applications for these connectors are within industrial, automotive, consumer and computer product fields.

Female Sockets

Female sockets or IDC connectors are made of a thin base plastic with a U-shaped contact surface that mates with male pins. They are generally designed for use with crimp tools to create connections with IDC cables. These sockets may also be used with standard ribbon cables having a 0.1” pitch which is ideal for internal wiring in many consumer, telecoms and industrial applications. Female sockets are one of the most reliable and cost-effective connections available and are perfect for computer mainboards, data acquisition, and printer applications.

Working Principles

The working principle of 851-91-031-20-001000 and other related rectangular connectors is straightforward. Connectors are inserted into PCBs, and the contact pins on the connectors are inserted into designated holes on the boards, which serve as the connection points. This ensures a strong, secure electrical connection between the components and the boards. Each connector has an insulation body that can withstand various environmental conditions, thus providing protection from corrosion and dust. Furthermore, the contacts are designed in such a way that they provide mechanical stability and low contact resistance.

Application Field

Rectangular connectors are widely used in a variety of applications, including industrial and electronic control systems, automotive, medical, military, and consumer applications. In the fields of industrial and electronic control, 851-91-031-20-001000 connectors are used for connection and signal transmission between control devices and signals. In the automotive field, these connectors provide stable connections between the control devices, including brake, accelerator, transmission control devices, and more. In the medical field, they are used for monitoring and data acquisition from the equipment. In the military field, they are used for aircraft, military communication, and other applications. Last but not least, these connectors are used extensively in consumer electronics applications such as computers, cell phones, printers, and more.

851-91-031-20-001000 and other rectangular connectors are the most commonly used type of connector due to their versatility, reliability, and cost-effectiveness. They offer various sizes, styles, and contact configurations, making them suitable for a wide range of applications and providing a reliable connection for all your project needs.
