Rectangular Connectors - Housings

DF33C-4DS-3.3C Application Field and Working Principle

Rectangular connectors, also called D connectors or multipin housings, are commonly used in distributed systems requiring fast data transmission between nodes.

DF33C-4DS-3.3C is a type of rectangular connectors which is widely used in various industry applications. Its application fields mainly include distributed control system（DCS）, PLC System, Automation, Industrial instrumentation and control systems and so on. The DF33C-4DS-3.3C provides an efficient connection between a power supply, signal box, display and other device interfaces.

The working principle of DF33C-4DS-3.3C is based on the use of a rugged plastic housing that contains three-ways contact towers. Inside the housing are two metal contacts separated by a central spacer. When the two terminals are connected, electricity flows through the connected metal contacts, and the terminal is pushed back in by the mounting posts so that the contacts remain engaged without needing to be released manually.

The DF33C-4DS-3.3C is specifically designed for use with low current (up to 1A) and lower voltage (3.3V) applications. They are also available in various configurations such as single and double rows, male and female, and screw and snap-in terminal mountings. DF33C-4DS-3.3C can support up to 79 signal contacts and also provide a secure grip for power-cable connections and power connection for devices such as LCD, monitor, etc.

Moreover, the design of the DF33C-4DS-3.3C includes features such as strain relief springs and vibration resistant features to protect the contacts from mechanical shock and vibration in harsh environmental conditions. In addition, they also have the capability to mount within extremely small spaces for efficient and integrated installation in tight spots.

The main advantage of using the DF33C-4DS-3.3C is that it is suitable for use with low-voltage applications. It produces reliable performance even in harsh working conditions. It also offers higher contact density with improved speeds and strong connection stability. Moreover, its cost-effectiveness and rugged design make it an attractive choice for various industry scenarios.

In conclusion, the DF33C-4DS-3.3C is a reliable, efficient and versatile type of rectangular connectors, which is widely used in many industry applications. It provides a secure connection between the driving device and the various components in the system while also providing protection from mechanical and environmental effects. It is ideal for low current and low voltage applications providing reliable performance at a lower cost.
