             For engineers and procurement partners, a high-quality wire-to-wire connector is never just "usable" — it must stand the test of parameter accuracy, environmental adaptability, and long-term stability.With over a decade of deep expertise in the connector field, Guangdong Deke Electric Co., Ltd. leverages the IATF16949 automotive-grade quality system as its endorsement. The launched SMH250 wire-to-wire connector uses actual test data to eliminate "connection hazards" and has become the top choice for engineers in product selection.

SMH250 All Core Parameters Fully Disclosed

Performance Clearly Traceable

 Flexible Adaptability: Supports multi-specification configurations of 2–15 wires, compatible with conventional wires of AWG28#–22# and PCB substrates with a thickness of 1.6mm. It easily meets the wiring requirements of various low-voltage devices and reduces adaptation troubles.
Stable Operation in Wide Temperature Range: The operating temperature ranges from -25℃ to 85℃. Whether in cold outdoor computer rooms or stuffy internal equipment, it can maintain stable performance and adapt to most indoor and outdoor working conditions.
Reliable Electrical Performance: With a rated voltage of 250V.AC/DC and a rated current of 3A, it meets the power supply and signal transmission needs of conventional low-voltage equipment; the contact resistance is ≤10mΩ, which ensures minimal signal loss and more accurate data transmission.
Full Safety Protection: The insulation resistance is ≥1000MΩ, and the voltage withstand performance reaches 1000V.AC/1min. It effectively prevents leakage and short-circuit risks and complies with electrical safety specifications.

SMH250 Dual Assurance of Material and

CraftsmanshipVisible Durability

Conductive Terminals: Adopt tin-plated phosphor bronze material. This material not only has better electrical conductivity than ordinary brass (with a conductivity of 20–28% IACS) but also features excellent corrosion resistance and elasticity. It can maintain stable contact even after multiple plugging and unplugging cycles, extending the product’s service life.

Housing: Made of nylon PA66 material, it complies with the UL94V-2 (0) flame retardant standard, and has both excellent insulation and mechanical strength, which can resist minor collisions and wear during daily use.

SMH250 Precise Matching for Multiple Scenarios

Unlock Practical Value

                    With its flexible adaptability and stable performance, the SMH250 has become a preferred connection component in multiple fields. Its application scope covers both civilian and industrial scenarios, with particularly outstanding adaptability and practicality, which can be specifically divided into the following categories:

Industrial Automation Field：This is one of its core application scenarios. It can be used for the connection between various modules in automated control cabinets, and is also suitable for signal and power transmission between sensors, relays, control panels and main control devices, such as automated testing equipment on production lines and power connection of robotic arm joints. At the same time, it can also meet the wiring requirements of power supply modules, ensure the connection stability of industrial equipment during long-term operation, and reduce faults caused by poor contact.

Consumer Electronics and Household Appliances Field：In household appliances, it can be used for the connection of power lines and control lines in the internal circuits of air conditioners, refrigerators, washing machines, and other appliances, ensuring the stable transmission of power supply and control signals for the devices. In addition, in the circuit connection of small consumer electronic devices such as smart home control panels and small power adapters, its small-pitch design also meets the compact structure requirements of such devices.

Electronic DIY and Education Field：It is a commonly used accessory for electronic DIY enthusiasts and students. For example, in electronic making projects related to Arduino and Raspberry Pi, as well as training or creation projects such as 3D printers and smart cars, it can quickly realize the connection between circuit boards and external components without welding, which greatly reduces the operation difficulty and facilitates later debugging and modification. It is often used in educational electronic kits to support the teaching of electronic knowledge.

Communications and Precision Electronics Field：In communication equipment, it can be used for the internal module wiring of some small and medium-sized communication terminals, ensuring the smoothness of signal transmission. Meanwhile, the SMH250 terminal connector is also suitable for various precision electronic devices. Its 2.5mm small-pitch design is compatible with high-density circuit design, which not only improves the connection stability of electronic components but also meets the requirements of precision equipment for the miniaturization and reliability of connection components.
