Rectangular Connectors: Headers, Male Pins

N3433-5203RB is a type of rectangular connectors, headers and male pins used for a variety of electronic applications. This article will discuss the application field and working principle of the N3433-5203RB connector.

Application Field and Form Factor

The N3433-5203RB rectangular connector is primarily used in the telecommunications industry as a multi-port connection device. The connector has a female header and an array of male pins that can be used to connect a variety of electronic components, such as printed circuit boards, speakers, sensors, and other devices. It has an overall form factor of 4.75 mm L x 3.55 mm W x 1.25 mm H, making it well-suited for space-constrained applications. It also has a standing-off feature that allows the connector to remain vertically aligned with the host device, making it easier to connect with other components.

Material and Contact Finish

The N3433-5203RB is made from thermoplastic and metal materials, making it able to withstand a wide range of temperatures and environmental conditions. The contacts are made from phosphor bronze with a gold finish, providing superior electrical conductivity. The flat-shaped contact design provides a low electrical contact resistance, ensuring reliable connection between the connected components.

Number of Contacts

The N3433-5203RB connector has a total of 12 contacts, with 6 pins on each side. The pins are mounted in a straight line, making it easier to insert and remove the connector from a host device. The contact arrangement is designed to minimize the risk of incorrect connections.

Working Principle

The N3433-5203RB rectangular connectors operate via the insertion of its male pins into the host device. When the pins are inserted, the female header slides over the pins, creating a secure connection. The clearance around the female header allows it to remain securely fastened to the host device, while the elevated pin design keeps it suspended in the host device, allowing for an easier connection.

Environmental Protection

The N3433-5203RB is designed for electromagnetic compatibility (EMC), with protection against electromagnetic interference (EMI) and radiated electromagnetic fields (RFI). The connector is also designed to be moisture and vibration-proof, making it reliable for harsh environments. The connector has a secured contact positioner that prevents incorrect connections, as well as an insulation displacement contact (IDC) system that allows the connector to remain securely connected even when subjected to shock and vibration.

Conclusion

The N3433-5203RB is a rectangular connector from Headers & Male Pins with a form factor of 4.75 mm L x 3.55 mm W x 1.25 mm H and 12 contacts with 6 pins on each side. The connector is primarily used for telecommunications applications and has been designed for electromagnetic compatibility. It is also resistant to moisture and vibration, making it suitable for harsh environments.
