DBMY25PTI

D-sub connectors, also known as D-subminiature or sub-D connectors, are electrical connectors commonly used in the world of personal computer hardware. They are named due to their distinct shape, which resembles the letter D. D-sub connectors are generally used to provide connections between modular communication equipment. It’s often used in audio/video and data signals.

The D-sub family comprises of several types, including those named DB15, DB25, DB37, DB44, DB47, DB50 and DB9. DB25PTI (25 polarity terminals on insertion) is a type of D-sub connector featuring 25 poles that are polarized on insertion. It is typically used in applications that involve data rates up to 56 Kbits/s and telecom system applications.

DB25PTI connectors are designed to minimize the incidence of cross-talk and noise, which is a major issue in high-speed data transmission applications. A typical high-speed data transmission signals is highly vulnerable to the interference of other signals and disturbances and needs to be shielded, making it extremely important for the DB25PTI connector to take the necessary measures to reduce cross-talk and noise.

The DB25PTI connector features having built-in-shields for the overall protection of the connector and dielectric withstanding voltage to protect the contacts. It also features superior electrical performance highly suitable to IEEE 1096/ISO RC and IEEE 1109/ISO SC standards. Additionally, DB25PTI features high dielectric strength reaching up to 500VAC and is RoHS compliant to meet environmental standards and requirements of global applications.

The DB25PTI connector is made of high temperature thermoplastic insulator material and contact with silver or gold plating to ensure superior electrical performance. The DB25PTI connector’s casing and contact point metal can me made of either steel or stainless steel with appropriate plating. It’s typically found in various kinds of instrumentation, data recording, communication, automotive, aerospace and commercial markets.

In terms of its working principle, the DB25PTI connector consists of a receptacle and mating connectors. The receptacle is a female connector which contains sockets where the set of pins of the mating connector fits. There are 25 contact points in the DB25PTI connector which allows for connection of up to four contact points on each row. The mating connectors, which can be either male or female, have pins that fit into the sockets on the receptacle. Once the pins of the mating connectors fit into the receptacle, the electrical connection is complete.

DB25PTI connectors are commonly used for a variety of applications, ranging from analog and digital video, high definition audio, contact closure to PC keyboard interfaces. In addition, it can also be used as a connection in radios, commercial controllers, process controllers, gateways, crimping machines and more.

In conclusion, DB25PTI connectors are one of the most common and widely used varieties of D-sub connectors, offering superior electrical performance, high temperature thermoplastic insulation and environmental compliance. It’s popularly used in a variety of different applications, from data transmissions and telecoms to instrumentation and automotive, and is a reliable and cost-effective way to create connections with the right specifications.
