The BSW-127-04-G-D, a rectangular connector without mounting ears and with a raised flange, is one of the most widely used rectangular connectors, typically seen in commercial, industrial, and automotive applications. It is a high-performance, low-cost, and reliable solution to a variety of connection problems.

The BSW-127-04-G-D, commonly known as a "DeltaConnect" or "Molex/Sumitomo" connector, consists of a number of terminals that are arranged in a specific pattern. The design is based around the "127" terminal pattern, with four industry-standard "G" sized (14-28 AWG) power contacts and four industry-standard "D" sized (17-32 AWG) signal contacts. The terminals are terminated into the plastic housing with solder, crimp, or screw connection methods depending on the application requirements.

The primary focus of the BSW-127-04-G-D is power transmission. The terminals are configured to provide both power and ground voltages up to 18A, in addition to the 2A signal connections. The raised flange on the housing ensures that there is enough air gap between the board and the housing to provide proper insulation when transmitting higher voltages or currents.

The most important aspect of the BSW-127-04-G-D is its working principle. When the flat receptacle and housing of the connector is fitted together, the terminals inside the housing are mated securely, forming an electrical connection between the devices. External forces cause the terminals to be pressed together, ensuring a secure connection. The terminals then become locked in, preventing them from loosening or coming apart even if the device is subjected to vibration or shock.

The BSW-127-04-G-D has a wide variety of applications. It is commonly used in instrumentation, automotive, telecommunication, and consumer electronics applications. Due to its reliable performance, it is used in a variety of high-temperature, high-voltage, and high-humidity applications. It is also used in marine applications, as the heavy-duty construction of its terminals and housing ensures durability, even in harsh environmental conditions.

With its simple and reliable design, the BSW-127-04-G-D provides a convenient and cost-effective solution for a variety of connection problems. Its wide range of applications and working principle make it an ideal choice for a variety of industrial and commercial applications.
