# DB - 25P - A191 - K87 Product Series Introduction
## 1. Overview
The DB - 25P - A191 - K87 product series represents a cutting - edge solution in the realm of electronic connectivity and data transmission. Engineered with precision and innovation, this series is designed to meet the diverse and demanding requirements of modern industries, including telecommunications, industrial automation, and data centers.
## 2. Physical Design
### Connector Type
The "DB - 25P" in the product name indicates that these products feature a 25 - pin D - Subminiature (DB) connector. The D - Sub connector is a well - established and widely used standard in the electronics industry. Its robust design with a trapezoidal shape and metal shielding provides excellent mechanical stability and protection against electromagnetic interference (EMI). The 25 - pin configuration offers a sufficient number of pins to support a variety of signal types, making it suitable for complex data and power transmission applications.
### Build Quality
The A191 in the series designation reflects the high - quality build of these products. They are constructed using premium materials that ensure durability and long - term reliability. The connectors are designed to withstand harsh environmental conditions, including temperature variations, humidity, and mechanical stress. The housing is made of a high - strength plastic or metal alloy that provides excellent protection for the internal components.
### Keying and Coding
The "K87" in the product series may refer to a specific keying or coding mechanism. Keying is an important feature in connectors as it prevents incorrect mating, which can lead to damage to the connectors or malfunction of the connected devices. The unique keying or coding of the DB - 25P - A191 - K87 series ensures that the connectors can only be mated in the correct orientation, enhancing the overall safety and reliability of the system.
## 3. Electrical Performance
### Signal Transmission
The DB - 25P - A191 - K87 series is capable of high - speed and reliable signal transmission. It can support a wide range of signal types, including analog and digital signals. The connectors are designed to minimize signal loss and distortion, ensuring that the data transmitted between devices is accurate and error - free. This makes them ideal for applications such as video transmission, serial communication, and control signal transfer.
### Power Handling
In addition to signal transmission, these connectors can also handle power. They are rated to carry a certain amount of electrical current, which allows them to power connected devices or provide power for internal components. The power handling capacity is carefully designed to meet the requirements of different applications while maintaining safety and reliability.
### Impedance Matching
To ensure optimal signal transmission, the connectors in the DB - 25P - A191 - K87 series are engineered with precise impedance matching. This helps to reduce reflections and standing waves, which can degrade the signal quality. The impedance matching is maintained across the entire frequency range of operation, ensuring consistent performance.
## 4. Compatibility
### Device Compatibility
The DB - 25P - A191 - K87 series is highly compatible with a wide range of devices. It can be used with computers, servers, industrial controllers, and other electronic equipment that support the DB - 25 connector standard. This makes it easy to integrate these connectors into existing systems or use them in new installations.
### Cable Compatibility
These connectors are also compatible with a variety of cables. They can be used with shielded or unshielded cables, depending on the specific requirements of the application. The cable termination process is straightforward, and the connectors are designed to provide a secure and reliable connection to the cables.
