D-Sub connectors are a popular type of connector that consists of two or more parallel rows of contacts. They are frequently used in computer and electronic applications for data transfer. The DC-37P-A191-K87 connector is a D-Sub connector widely used in various applications and is noted for its reliability and ease of use. This article will discuss the application field and working principle of the DC-37P-A191-K87 D-Sub connector.

The DC-37P-A191-K87 D-Sub connector is often used in applications that require a high-speed data connection between two devices. The connector offers reliable performance in these applications due to its robust design and reliable contact arrangement. Additionally, it is shielded to reduce electromagnetic interference (EMI), which is essential in some applications. The DC-37P-A191-K87 D-Sub connector is widely used in industries such as automotive, medical, and industrial automation.

The DC-37P-A191-K87 D-Sub connector features a 37-pin configuration that allows it to support both differential and single-ended data transfer. The connector has a maximum rated voltage of 500 V DC, a maximum rated current of 4 A, and an operating temperature range of -20°C to +105°C (-4°F to +221°F). Additionally, its insulation resistance measures greater than 1,000MΩ at 500 V DC.

In terms of the working principle of the DC-37P-A191-K87 D-Sub connector, it is based on the electrical contact between the mating pins. The contact is known as a “dry mating” because it does not require the use of additional lubricating materials, such as a lubricant or solder paste. The contacts of the connector are designed to make an electrical connection when the two mating pins are inserted into the connector’s housing. The contacts are held firmly in place by a tension spring that secures the contact in the mating position. The contacts are also designed to “self-clean”, which prevents the accumulation of dirt and dust that can negatively affect the connector’s performance.

In order to ensure reliable electrical contact between the two mating pins, the DC-37P-A191-K87 D-Sub connector is equipped with a pair of gold-plated beads that are positioned between the pins. These beads, known as “contacts”, are designed to ensure a tight fit and allow the two pins to make a secure electrical connection. The contacts are designed to reduce the resistance of an electrical connection and to provide EMI/RFI protection.

Finally, the DC-37P-A191-K87 D-Sub connector is also designed to be rugged and durable. It features a robust die-cast zinc shell that provides excellent mechanical strength and resistance to corrosion and oxidation. The connector also features an array of stainless steel clips that secure the contacts and protect them against vibration and mechanical shock.

The DC-37P-A191-K87 D-Sub connector is designed to meet the most demanding electrical interface requirements. Its reliable contacts, robust construction, and EMI/RFI protection make it ideal for a variety of applications, including automotive, medical, and industrial automation. The ease of use and robust performance of the DC-37P-A191-K87 D-Sub connector ensure it is a popular choice for many applications.
