Introduction

D-sub connectors, also known as DB connectors, are electrical connectors which typically carry a signal and two power contacts. 6STF37PAT05S20X is one of the most common D-sub connectors available. In order to better understand this connector, this article will discuss its application field and its working principle.

Application Field

The 6STF37PAT05S20X is a full-size, male-female connector with a 7-pole contact arrangement. It is most often used in computer and audio applications. The connector has two solderable power contacts, and five signal contacts. Typically, the two power contacts are connected to the motherboard, and the remaining five signals are connected to peripherals. The connector is also commonly used in automotive electronics applications between the control unit and the sensor, or signal processing unit.

The 6STF37PAT05S20X has an extended operating temperature range from -55°C up to +125°C, making it ideal for harsh environmental conditions. It is also rated with UL94V-2 flame retardancy, making it suitable for applications in home, office, and industrial settings. The full shell design of this connector makes it highly resistant to dust and water, ensuring reliable operation.

Working Principle

The 6STF37PAT05S20X connector consists of two mating parts: the male header and the female receptacle. The male header has two power contacts and five signal contacts, which are electrically joined when mated with the female receptacle. The female receptacle has two power contacts and five corresponding signal contacts. The two power contacts are machined with a larger diameter, making them easily identifiable.

The male header enables the electric signal to pass between the computer and peripheral device, while the female receptacle ensures proper mating between the two components. The connector has an internal contact threading which ensures better electrical conductivity between the mating parts. It also prevents any mechanical loosening or electrical disconnection of the contacts, ensuring reliable performance even under high vibration conditions.

The mounting holes on the 6STF37PAT05S20X are optimized for secure mounting on a board. All mounting screws and nuts are made with zinc plating, which allows for easy assembly and good anti-corrosion performance.

Conclusion

The 6STF37PAT05S20X is a versatile D-sub connector, suitable for use in a variety of applications. Its extended temperature range and flame retardancy make it suitable for harsh environmental applications. Additionally, its robust construction and internal contact threading ensure reliable operations even under high vibration conditions. The mounting holes on the connector ensure secure mounting on a board, facilitating easy assembly. As such, it is a popular choice for applications needing reliable data and power transfer.
