Rectangular Connectors - Headers, Receptacles, Female Sockets

Rectangular connectors - headers, receptacles, female sockets, part number 801-43-005-40-002000, are all parts of the same family type of connectors, and generally have similar characteristics. They have rectangular mating face patterns that are especially designed to minimize the risk of misconnection. These parts are created to fit into a mating plug or receptacle header that is designed to match the shape of the connector’s mating face.

Rectangular connectors (headers, receptacles and female sockets) provide reliable electrical connections because they feature a high mating force, as well as tightly sealed contacts, that guard against both particle and moisture intrusion. Depending on the specific part number, these connectors can be supplied with either integral or removable contacts. For the most demanding requirements, they offer high amperage and voltage ratings, as well as environmental protection from dust, dirt, and water. As an additional feature, they are also designed to provide electromagnetic interference (EMI) protection by minimizing arcing and/or contact chatter, which is an electrically generated noise.

Applications

Rectangular connectors are commonly used for a wide range of high-reliability and harsh-environment applications, such as: medical instruments, mechanized and automated assembly equipment, telecommunication, computer systems, and audio and video equipment. They are also suitable for splash/drip applications, where they provide protection against random/short-term exposure to minor dust, dirt, and water.

Working Principle

The mating interface of the rectangular connector generally consists of several parallel channels that are separated by a thin spacing. The active part of the connector is the housing, which is designed to make contact with the mating header. The contacts may be either retained in place, or held in the housing by an assembly clip. When the connector is mated with a matching header, the evenly spaced contacts are compressed. This makes an electrical connection with the mating header and closes the internal circuit.

The housings of the rectangular connectors are designed with contact support walls to ensure proper contact alignment, which prevents contact chatter and other EMI problems. This enables the receptacle to mate perfectly with the header and provides a reliable connection for attaching and securing appropriate cables.

Connectors like the 801-43-005-40-002000 which feature removable contacts are also available. These contacts can be either re-used (“recycled”) or replaced with new contacts when necessary. This type of contact retention system makes it more convenient to maintain and repair the connectors as needed, without having to discard them.

Conclusion

Rectangular connectors - headers, receptacles, and female sockets, part number 801-43-005-40-002000, are robust parts designed for a wide range of applications. The high-reliability and harsh environmental requirements of such applications are met by providing tightly sealed contacts that are capable of withstanding dust, dirt, and water, as well as providing high amperage and voltage ratings. The mating face patterns of rectangular connectors also help to minimize the risk of misconnection. This family of connectors is also available in versions with removable contacts, which simplifies maintenance and repair.
