Introduction

DBR stands for "Dual Balanced Rated", and it is a type of D-Sub connector. DBR25PTI (Dual Balanced Rated 25 Position Twist In), is specially designed with features such as metal shells, threaded inserts and rugged construction, to make them suitable for extreme environment applications.

Application Field

DBR25PTI D-Sub connectors are most commonly used in industrial and military applications in harsh environments. They can work in temperature (-55°C to +105°C) and are designed to withstand extreme pressure, vibration and shock. Their shielded cable systems can provide excellent performance in EMC application. The threaded wire inserts with single wires and multiple grounded shields allow the cable to be better secured, so that it can withstand high levels of vibration, shock, flexing or repeated mating cycles.

Working Principle

The DBR25PTI D-Sub connector consists of three parts: the connector, a circular contact, and a threaded wire insert. The circular contact has a metal shell, which is mechanically coupled to the connector housing, and contains pins. The threads of the wire inserts provide extra security against vibration, shock or flexing. When mated, the cables secure in place, with one or more contacts engaging the contact pads on the connector. This provides a reliable communication between the cable and the circuit board.

Conclusion

In conclusion, the DBR25PTI D-Sub connectors are an ideal choice for extreme environment applications. Their rugged construction and threaded wire inserts provide excellent performance, making them suitable for industrial and military applications. The shielded cable systems are designed to provide secure and reliable communication in harsh environments, while the metal shells protect the contacts from damage.
