SSQ-140-03-T-S-RA

Rectangular Connectors - Headers, Receptacles, Female Sockets

Rectangular connectors are available in a wide variety of types, including headers, receptacles and female sockets. In this article, we will focus on the SSQ-140-03-T-S-RA, one of the industry\'s most popular rectangular connectors, and discuss its application field and working principle.

The SSQ-140-03-T-S-RA connector is a 2.54 mm pitch-based board-to-board connector, with a dual-beam contact system design for superior electrical performance in high-density applications. It adopts a simple reverse-key operation, which makes it suitable for both 0.2 mm and 0.3 mm thick board applications. This connector provides excellent mating reliability, due to its 40 mm centerline with two-point positions and N/PE locking system.

Application Field

The SSQ-140-03-T-S-RA connector is suitable for a wide variety of applications, including consumer electronics, computing equipment, wireless products, automotive electronics, medical equipment, and industrial devices. It is particularly well-suited for space-constrained applications due to its smaller size and higher density of contacts. Additionally, its two-point contact system allows for superior signal integrity and low contact resistance in challenging environments.

The SSQ-140-03-T-S-RA is also RoHS-compliant, which makes it suitable for high-volume, cost-sensitive applications. Additionally, it is highly reliable and have a long service life, making them highly suitable for rugged and harsh environments.

Working Principle

The SSQ-140-03-T-S-RA connector operates on the principle of contact force. It has an integrated tissue-level mating contact that utilizes a dual-beam contact system for improved electrical performance. The two contact beams are held firmly in place, and provide increased reliability and stability for the electrical connection.

In addition, the SSQ-140-03-T-S-RA connector has an optimized contact design to provide the highest possible contact forces. This contact force is achieved by using two independent contact points, which transmit force both vertically and horizontally. No matter how much the connector is twisted or bent, the contact force will remain firm and provide a reliable connection. The SSQ-140-03-T-S-RA connector also provides improved mechanical robustness, thanks to its dual-beam contact system.

The SSQ-140-03-T-S-RA connector is one of the most popular rectangular connectors on the market. Its reliability and robustness make it a suitable choice for a wide range of applications, from consumer electronics to industrial devices. Additionally, its dual-beam contact system provides superior electrical performance, as well as improved signal integrity and low contact resistance.
