Product parameters
The 1.27mm female single or double-row straight-type connector, as a commonly used component for board-to-board connections in electronic devices, possesses both the common advantages of single-row and double-row styles, and each has its own characteristics suitable for different scenarios. The details are as follows:
Common core characteristics
Universal specification with strong adaptability: 1.27mm is the industry standard pitch, which can seamlessly connect with straight-type pins of the same specification and various PCB boards. The adaptability is at its peak. The pin specification range is wide, including single row from 2 to 50 pins and double row from 4 to 100 pins. Some models also support customization of pin length and insulator height, which can meet the installation gap and connection requirements of different PCB boards. Some models come with positioning pins, which can further improve the installation accuracy.
Reliable material and stable performance: The contacts are mostly made of brass or phosphor bronze, which have excellent conductivity and elasticity. The surfaces are often treated with nickel base gold plating or tin plating, which not only enhances conductivity but also resists corrosion and oxidation. The insulators commonly use materials such as PBT, PA6T, and LCP that meet the UL94 V - 0 flame retardant standard. Some are reinforced with glass fibers, resulting in higher structural strength. The rated current is typically 1A, the contact resistance is 20mΩ, the insulation resistance is at least 1000MΩ, and the working temperature ranges from -40°C to 105°C. This ensures stable signal and power transmission, reduces losses and failure risks.
Easy installation and suitable for mass production: It is divided into DIP (dip-in-place) and SMT (surface mount technology) types. The DIP model requires no complex operations and can be easily soldered even by beginners. The SMT model can be adapted to automated assembly lines. The packaging options include bagged, boxed, tube-shaped and roll-shaped, which can meet the small-batch requirements of electronic DIY as well as industrial large-scale mass production. Most of them comply with RoHS environmental standards.
Exclusive features of the single-row straight-type bra cup
Compact structure, saving space: The single-row layout has no redundant pins, the overall size is small, occupying less area on the PCB board, and it will not cause layout pressure to small circuits. It is particularly suitable for scenarios with simple circuits.
Suitable for simple connection scenarios: The number of pins is relatively small, precisely matching the low-pin requirements, such as power supply for LED strips, signal connection for buzzers, etc., for simple circuits. Moreover, the insertion and removal operation is flexible. In the simple expansion interfaces of development boards like Arduino and Raspberry Pi, it can meet the needs of frequently replacing small modules, making debugging and replacement very convenient.
Exclusive features of the double-row straight-type female connector
High density with high transmission efficiency: The dual-row design significantly increases the pin density, allowing for more connection points within the same PCB space. It can simultaneously transmit more signals and power, suitable for high-speed and high-density data transmission scenarios. It is applicable to devices such as communication equipment and industrial PLC control boards that require multi-channel signal interaction.
Adaptation for complex module interconnection: Suitable for connecting complex modules that require multiple lines, such as OLED display screens, camera modules, etc. It can not only ensure stable connection between these modules and the mainboard, but also make the wiring more orderly, avoiding faults caused by messy lines. It is also suitable for the modular interconnection requirements of internal modules in medical portable detection instruments, drones, etc.
