Rectangular Connectors - Accessories

Rectangular connectors are frequently used in many high-impact applications such as automotive, military, aerospace, and medical products, where reliable connection is essential. The DF33C-3RS-3.3 is one of the most popular rectangular connectors, widely used in today’s electronic applications. It is a 2mm pitch, single-row, surface mount, 3-pin connector, designed for flexible printed circuit boards (FPC). This article will discuss the applications and working principles of the DF33C-3RS-3.3.

Application Field:

Due to its reliable connection and small size, the DF33C-3RS-3.3 is often used for applications or products that require a compact and reliable connector. Such products include, but are not limited to, portable electronics, telecom equipment, automotive, medical equipment, and consumer electronics.

In automotive applications, for example, the connector is used to connect parts such as ECUs, sensors, power, and other components. In portable electronic products, such as digital cameras and mobile telephones, the connector is used to connect display, image sensor, audio, and power devices. In telecom equipment, such as routers, switches, and terminal equipment, the connector is used to connect sensors, power, RF antennas, fiber-optic components, and other components.

Working Principle:

The DF33C-3RS-3.3 is designed for a range of FPC applications. The 2mm pitch between the pins ensures a reliable connection and improved contact performance, reducing the risk of electrical short circuits or misaligned connections. The contact pins are made of brass and are securely held in place using a plastic clamping system, which prevents signal loss or damage to the pins during insertion or removal.

The ground spring ensures that the connector remains securely fastened to the FPC, eliminating the need for additional screws or anchors. The connector also features two actuation rails on either side of the actuator, which provide an easy way to disengage the locking mechanism and gently pull the connector away from the board. Furthermore, the DF33C-3RS-3.3 is designed to be RoHS compliant, making it suitable for use in many different applications.

In addition to the reliable connection, the DF33C-3RS-3.3 also features adjustable polarisation. This allows users to align the pins in the correct orientation regardless of the mating component\'s orientation. This feature ensures that the connector is fully compatible with different mating components in a variety of applications.

Conclusion:

The DF33C-3RS-3.3 is one of the most popular rectangular connectors, widely used in today’s electronic applications. In addition to its reliable connection, the connector also offers adjustable polarisation, RoHS compliance, and compact size. It is often used for applications or products that require a reliable and compact connection, such as portable electronics, telecom equipment, automotive, medical equipment, and consumer electronics.
