DBM9W4S300N Connectors, Interconnects

D-Sub Connectors are an imperative part of computer and telecom networks, opening up the flow of data from one device to the next. The most popular type in this family of connectors is the DB9W4S300N. This article covers its application fields and the way in which it works.

DB9W4S300N Connector Overview

The DB9W4S300N connector belongs to the class of D-Sub connectors. Its identifying code, DB9W4S300N, stands for the dimensions of the connector: DB9 means that it has 9 pins, W4 signifies that it adheres to the military specification MIL-DTL-24308, and S300 points to the range of rated current up to 300mA. Its insulation resistance is greater than 1000MΩ, and it is equipped with solid screw-locking screw terminals. It’s suitable for circular, surface mount, and straight applications.

Application Fields of DB9W4S300N Connectors

The DB9W4S300N connector is used in diverse applications. Here are a few of the most common uses:

• Facilities Networking: The DB9W4S300N is used in the wiring of industrial facilities for networking between various parts of the building. This includes servers, computers, routers, and switches.
• Telecommunications: The DB9W4S300N can be used to connect various telecom devices such as modems, cellular devices, and phones.
• Robotics: Robotics components are often integrated with the same connectors. Standard connections for peripherals and baseboards are commonly realized with DB9W4S300N connectors.
• Measuring Instruments: DB9W4S300N connectors are used to create reliable connections between measuring instruments and other electronic devices.
• Data Acquisition: Interconnections between the data acquisition system and the computer are achieved with the DB9W4S300N connectors.
• Power Protection: Devices used for power protection often have DB9W4S300N connectors.
• Industrial Automation: Precision sensing, control, and automation systems use DB9W4S300N connectors for data and power.

Working Principle Of DB9W4S300N Connector

When connecting two devices through the DB9W4S300N connector, the working principle is direct contact. The tip of the connector is inserted into the receiving port or the receiving module. This ensures good contact between the pins of the connector and the receiving module. This allows the metal pins to transfer data or power between the two connected devices. In certain applications, screws may also be used to secure the connection.

The contact of the DB9W4S300N connector is produced by gold plated pins. The specialized solid screw-locking screw terminals offer an established and secure connection. The insulation on the wire and the connector itself is also important and should be carefully monitored. It should be ensured that the insulation does not break down, leading to sparking or short circuits.

Conclusion

The DB9W4S300N connector is an essential component of many computer and telecom systems. It has various application fields such as robotics, telecommunications, measuring instruments, data acquisition, power protection, and industrial automation. The principle of working of the connector is direct contact by gold plated pins and is secured with screws. Its insulation against leaks should be observed with interest.
