SCN terminal connector
Low Resistance & Anti-Loosening + Wide Temperature
Your Go-To Choice for Reliable Connection & Solid Core Strength
In the connection system of electronic devices, terminal connectors serve as both a "bridge" and a "barrier"—their contact reliability and protection performance directly affect the operational safety and service life of the equipment. With years of in-depth expertise in the connector industry, Guangdong Deke Electric Co., Ltd. has launched the SCN2.5 series terminal connectors. Centered on a 2.5mm precision pitch design, this series has become a trusted choice in fields such as consumer electronics, smart homes, and small instruments and meters, thanks to its solid parameter performance and user-friendly structural design. This article will focus on two core components: the SCN2.5 board-to-board terminal and the SCN2.5 housing, guiding you to understand the quality strength behind them.

SCN Board-to-Board Terminal
The Core Carrier for Precision Conduction
As the direct connection carrier between wires and PCB boards, the SCN Board-to-Board Terminal undertakes the task of precise conduction of current and signals. Designed around three core dimensions—"Low Loss, High Stability, and Easy Assembly"—it has undergone multiple rounds of actual testing and optimization, resulting in stable and controllable performance indicators.
Rated Specifications: Supports a rated current of 3A AC/DC and a rated voltage of 250V AC/DC, meeting the power supply and signal transmission needs of low-to-medium power equipment, and covering mainstream scenarios such as consumer electronics and smart homes.
Contact & Insulation Performance: Maximum contact resistance is only 20mΩ, which effectively reduces signal transmission loss and ensures precise data conduction; insulation resistance is no less than 1000MΩ, and withstand voltage can reach 1500V AC (no breakdown for 1 minute), eliminating leakage risks from the source.
Material & Environmental Friendliness: The terminal body is made of high-conductivity brass with a tin-plated surface, enhancing oxidation resistance and conductivity efficiency. The entire product complies with the RoHS environmental standard, being free of lead, cadmium and other hazardous substances, and meets the requirements of green production.
Compatibility Range: Compatible with 22-28AWG wires, supports conductors with a cross-sectional area of 0.12-0.34mm², fits PCB boards with a thickness of 0.8-1.6mm, and offers 2-20 circuit configurations. It meets the high-density wiring requirements of small-sized equipment.
SCN Board-to-Board Terminal
Core Advantages Quality in Every Detail
Anti-Loosening Design: Adopts a dual fixing structure of crimping + snap-fit. The pull-out force of the crimped wire can reach over 30N, resisting loosening during insertion and extraction, and the contact performance remains stable after PCB soldering.
Efficient Assembly: The terminal enables smooth mating and can be assembled without special tools, reducing labor costs and operational complexity on the production line while improving mass production efficiency.
Environmental Resistance: Operating temperature range covers -25℃ to +85℃, adapting to regular indoor and outdoor environments. Having passed the 24-hour salt spray test and vibration test, it maintains stable operation under humid conditions and temperature fluctuations.

SCN Housing
A Safety Barrier for Precision Protection
As the supporting protective component for the SCN Board-to-Board Terminal, the SCN Housing not only provides physical fixation but also isolates external dust, moisture, and electromagnetic interference, offering comprehensive protection for terminal connections. Its design achieves a precise fit with the board-to-board terminal, ensuring stable overall performance after assembly.
Structural Specifications: Adopts the same 2.5mm precision pitch design as the board-to-board terminal. The housing length is tailored to the number of circuits (2 to 20 circuits available), with an overall height of only 9.2mm and width of 4.8mm after installation. The ultra-miniature design greatly saves PCB board space.
Compatibility Performance: Perfectly engages with the SCN2.5 Board-to-Board Terminal, featuring a fit clearance ≤ 0.15mm after mating to ensure continuous current conduction. It supports the same rated current and voltage as the board-to-board terminal, without compromising transmission performance due to the protective structure.
Material Assurance: Adopts flame-retardant grade PA66 engineering plastic, meeting UL94 V-0 flame retardant rating. It resists combustion when exposed to fire, reducing the risk of equipment fires. With excellent anti-aging performance, the material resists brittleness and cracking during long-term use.
SCN Housing
Exclusive Protective Features
Designed for general operating environments, it features basic dust-proof and anti-miscontact functions. The inner wall of the housing is equipped with guide ribs to ensure precise alignment of the terminal during mating, avoiding pin damage caused by misalignment. The outer edge adopts a rounded corner design, reducing the risk of scratches to operators during assembly and enhancing operational safety.
