Rectangular Connectors - Headers, Receptacles, Female Sockets encompass a wide array of electronic components that provide the necessary bridge between two electrical nodes in a circuit. One of the most widely used electronic connector families belongs to the 207530-9 standard, also known as the Micro Header. This connector offers both design flexibility and high electrical properties, making it very popular among electrical engineers and hobbyists alike.

The 207530-9 Micro Header offers two primary advantages over other modular connectors: compact size and reliable performance. Its size enables it to fit in tight or constrained “dead” spaces in a circuit board, allowing for more dense electrical designs. It is also capable of handling both digital and analog signals, with an operating temperature range of up to 125 degrees Celsius, offering reliable performance in operating conditions that require a higher temperature rating.

The core of the 207530-9 system is a “header”, which is a socket that receives a mating “receptacle” and then automatically locks into place when the two components are connected. At the contact points, the header utilizes two levels of contacts—a primary contact and a secondary contact that are both “shimmed”. The shimmed contacts provide a redundant contact system, allowing the socket to make contact at two points, increasing electrical conductivity and reliability. This two-level contact system provides improved performance for signals that require short-term high current.

The 207530-9 system also has an integral contactless interface, meaning that it can detect the presence of a mating device before making physical contact. This contactless interface requires a sensor and a ferrite body to make contactless connection possible. The sensor monitors the electrical field generated by the ferrite body, and when a mating device is inserted into the header, the sensor is able to detect the electrical change and make the necessary connections.

The 207530-9 system also has a metal backshell that provides additional shielding and protection from the environment. The backshell is typically die-cast metal with an interlocking latching system, or it may also be available with a matching plastic polypropylene material that can be fitted — providing additional robustness from the environment. The backshell includes strain relief clamps, which prevent any force or strain from being placed on the electrical connections.

The 207530-9 system is also often used with female sockets, which are the complementary part of the header that receives the mating plug. Female sockets are often preferred for operations that require frequent connections and disconnects, or for operations that require extra protection against hazardous environments. Female sockets are typically made from a molded thermoplastic body, which provides electrical insulation and superior environmental protection.

The 207530-9 system is considered the gold standard in the world of electronic connectors. It is one of the most reliable and flexible connector families available and is ideal for a wide range of applications. Its durable construction and wide operating temperature range make it an excellent choice for both extreme and harsh environments, while its compact size makes it useful for circuit boards with limited space.
