DF81-40S-0.4H(52) Connectors, Interconnects

DF81-40S-0.4H(52) is an example of rectangular connectors, belonging to the header, receptacle, and female socket categories of components. This particular type of rectangular connector is suitable for applying power and data signals between two electronic devices, as part of a board-to-board connection. The connector is composed of three basic parts: a male header, receptacle, and female socket that each feature a row of 40 pins.

A common application of DF81-40S-0.4H(52) is in boards and systems used in the communications industry. For example, it is well-suited for applications in radio base stations, cellular phone systems, and automotive infotainment systems. Additionally, the connector’s small size makes it useful for applications where board space is limited.

DF81-40S-0.4H(52) connectors are designed to provide reliable contact performance, protect against electro-migration, and offer resistance to chemical corrosion. The proposed design is fully compliant with the ROHS environmental protection standards. The specific dimensions of the connector are: width—11.3mm, height—14.2mm, and depth—3.7mm.

The electrical characteristics of DF81-40S-0.4H(52) connectors depend on the environment they are used in. For example, in an open air environment the contact resistance is maximized at 10 milliohms while the insulation resistance is at least 1000 megaohms. The maximum current carrying capacity of the DF81-40S-0.4H(52) connector is 40 amperes, while the maximum voltage operating is within the range of 1KV-3KV.

When connected, the DF81-40S-0.4H(52) socket makes electrical contact with a female pin from the header. This contact is held together by a spring-loaded retention clip that securely holds the connector in place. The clip also helps to shield the connection from outside interference. The overall connection is designed to withstand typical vibrations in industrial environments.

To ensure proper performance and safety, the DF81-40S-0.4H(52) connector must be wired correctly. The pin pitch of the connector is 0.4mm and each individual socket terminal is rated to handle up to 2A. Wiring mistakes should be avoided since incorrect wiring could result in decreased signal quality and immediate or long-term damage to the device.

In the end, the DF81-40S-0.4H(52) connector provides a reliable and robust way to connect two electronic components. This type of connector is suitable for a wide range of applications, from board-level connections in the communications industry to personal device applications. The connector’s small size and high current capacity allow it to be used effectively in space-constrained areas.
