Title: Exploring the Mainstream Rectangular Connector Product Line Parameters


In today's technologically advanced world, the demand for reliable and efficient electrical connectors is ever-increasing. One such type of connector that has gained immense popularity is the mainstream rectangular connector. These connectors are widely used in various industries, including automotive, aerospace, telecommunications, and consumer electronics. This article aims to delve into the key parameters that define the mainstream rectangular connector product line, highlighting their importance and impact on different applications.

1. Size and Form Factor:

The size and form factor of a rectangular connector play a crucial role in determining its compatibility with different devices and systems. These connectors are available in various sizes, ranging from miniature to large-scale connectors, catering to diverse application requirements. The form factor, such as the number of pins, pin spacing, and overall shape, is designed to ensure proper mating and alignment between connectors, ensuring reliable electrical connections.

2. Contact Density and Configuration:

Contact density refers to the number of contacts or pins within a given area of the connector. Higher contact density allows for more signals or power to be transmitted simultaneously, making it ideal for applications requiring multiple connections. The configuration of contacts can vary, including single-row, dual-row, or even multi-row arrangements, providing flexibility in terms of signal routing and power distribution.

3. Signal Integrity and Shielding:

Signal integrity is a critical parameter in high-speed data transmission applications, where maintaining the integrity of the signal is crucial. Mainstream rectangular connectors often incorporate features like impedance matching, controlled crosstalk, and shielding to minimize signal degradation and electromagnetic interference (EMI). These features ensure reliable data transmission, making them suitable for applications like high-speed data networks, computer peripherals, and telecommunications.

4. Environmental and Mechanical Durability:

Rectangular connectors are designed to withstand harsh environmental conditions, including temperature extremes, moisture, dust, and vibrations. The product line parameters include various levels of environmental sealing, such as IP (Ingress Protection) ratings, to ensure protection against these elements. Mechanical durability is also a key consideration, with connectors being subjected to frequent mating and unmating cycles. The product line parameters define the connector's durability, including the number of mating cycles it can withstand without compromising its electrical performance.

5. Material Selection and Plating Options:

The choice of materials used in the construction of rectangular connectors is crucial for their overall performance and reliability. Common materials include thermoplastics, thermosets, and metal alloys. The product line parameters specify the material selection based on factors like electrical conductivity, mechanical strength, and resistance to environmental factors. Plating options, such as gold, tin, or silver, are also defined to enhance the connector's conductivity, corrosion resistance, and solderability.

6. Mounting and Termination Options:

Rectangular connectors offer various mounting and termination options to suit different application requirements. These options include PCB (Printed Circuit Board) mount, panel mount, cable-to-board, and wire-to-board configurations. The product line parameters define the specific mounting and termination options available for each connector, ensuring compatibility with the intended application.

7. Industry Standards and Certifications:

To ensure interoperability and compatibility, mainstream rectangular connectors adhere to industry standards and certifications. These standards, such as MIL-DTL-38999, IEC 60603, and SAE AS81714, define the electrical and mechanical characteristics of the connectors. Compliance with these standards ensures that the connectors can be seamlessly integrated into existing systems and meet the required performance criteria.


The mainstream rectangular connector product line parameters encompass a wide range of factors that define their compatibility, reliability, and performance in various applications. From size and form factor to signal integrity and environmental durability, these parameters ensure that connectors meet the specific requirements of different industries. By understanding and considering these parameters, engineers and designers can select the most suitable rectangular connectors for their applications, ensuring seamless connectivity and optimal performance.
