D-Sub connectors are a type of electrical connector most commonly found in low-tech consumer applications such as computer devices, networking peripherals and home audio/video systems. They are popular as they offer a relatively low-cost connection alternative to higher cost, higher-performance electrical connectors such as RJ45 connectors, fiber connectors, and circular connectors.

DE9P1A0NK87 is a D-Sub connector type of which has the form factor of DE09, a 9 pin configuration. This type of connector has a couple of defining features. Firstly, it is geared mostly for data transmission applications and comes with a low-range current rating of 0.5 A. The latter is important because 0.5 A is the minimum current rating for reliable high speed data transmission.

The DE9P1A0NK87 also has a second important feature. The external shielding helps to provide effective electrical interference shielding over wide frequency ranges. The type of shielding is referred to as bi-directional shielding, meaning it not only stops interference entering the connection but also prevents the connected devices from leaking interfering signals into the surrounding environment.

The DE9P1A0NK87 connector is suitable for a range of applications such as data transfer for audio/visual devices, Ethernet and serial communications. Its use is most common in low voltage power supplies and in audio/video systems, such as televisions, computers, home theater systems, and gaming consoles.

The working principle behind the DE9P1A0NK87 is the same as most D-Sub connectors. It contains pins and sockets which attach directly to the cable cores. When the connector is plugged in, metal tongues on the socket and the pin contact and create a secure connection. Many models also use a strain relief mechanism to ensure the connected wires can withstand the load, without the pins losing their contact. The connector also contains a metal shield which provides electromagnetic interference protection.

The DE9P1A0NK87 is a cost-effective alternative to more expensive RJ45 connectors or even fiber connectors. It is useful for low power consumption applications in consumer electronics which require reliable and accurate data transfer. Its shielded design helps reduce interference from both internal and external sources.
