D-Sub Connectors

D-Sub connectors are an important part of modern electronics, commonly found in computers, TVs, and other electronic devices. These connectors provide a secure and efficient connection between two devices, such as a computer and a monitor, or a printer and a computer. The DBML25S500 is one example of a D-Sub connector. It has surface mount technology and is compatible with both insulated and uninsulated wires.

Application Field and Working Principle

The DBML25S500 is a D-Sub connector designed for high-speed data transfer in applications such as high-speed communication or data acquisition. It is a 25-pin panel-mount connector with housing made of polyphenylene-sulfide (PPS), a material that is tough and durable. It is designed to be splash-proof, making it suitable for use in damp or wet environments such as marine or industrial settings. It features a low-pass filter design, ensuring high-quality signal transmission and no loss of data.

This type of connector has two main components: the connector and the terminal. The terminal enables a connection between two devices. It features a flat face and a sliding contact bar. The contact bar slides into the connector, which features a hollow area that allows the contact bar to make contact with two metal contact surfaces inside. The connector then gets secured inside with a locking post that has a set screw to keep the contact bar in place and ensure a tight connection.

Another important feature of the DBML25S500 is its high electrical conductivity. Its copper alloy contact pins and plating provide excellent electrical conductivity and RF shielding properties. Furthermore, its twisted-pair cabling design allows for low-noise transmission and reduced EMI interference. It is also designed to have superior durability and resistance to abrasion, vibration, and shock thanks to its stainless steel locking post and contact bar.

Finally, the DBML25S500 is designed to withstand high levels of temperature and humidity, making it ideal for harsh industrial environments. It can operate from -55°C to 105°C and is rated for up to 90% relative humidity. It is RoHS compliant and is UL, CSA, and Nemko certified, so it is suitable for use in almost any application where high-speed data transmission is required.

In summary, the DBML25S500 is a high-speed D-Sub connector that is designed for reliable operation in harsh industrial environments. It features a low-pass filter design, excellent conductivity, and a twisted-pair cabling design for low-noise transmission. Furthermore, it is RoHS compliant and is UL, CSA, and Nemko certified. All these features make it ideal for high-speed data transmission applications and harsh industrial environments.
