Unlock the "DuPont" Series Terminal Connectors 
Multi-Scenario Adaptation, Precision Connection Defense

       In the field of electronic device connectivity, balancing "standardization" and "customization" has always been a core requirement. Guangdong Deke Electric has dedicated years to the R&D and production of terminal connectors. The launched DuPont Series Terminal Connectors, which include four variants—DuPont 2.0, DuPont 2.54, DuPont with Buckle, and DuPont with Lock—cover three core scenarios ("miniaturization, standardization, and anti-loosening") through differentiated designs. With precise parameters and stable performance, they have become a preferred connectivity solution in fields such as smart home, industrial control, and consumer electronics.

DuPont 2.0

Small pitch empowers the

"slimming and lightweight revolution" of devices

      To address the wiring needs of miniaturized electronic devices, the DuPont 2.0 Series adopts a 2.0mm pitch design to enable high-density installation, making it particularly suitable for space-constrained scenarios such as smart home controllers and portable instruments. Its contact plates feature a 1.0mm narrow-width design, and when combined with a dual-spring structure, they generate a stable contact force of 1.5N. The series supports wire connection of AWG 30-24 specification, and its parameter configuration of 2A/250V rated current fully meets the long-term operation requirements of low-power devices.

DuPont2.54Classic Universal Model

 Suitable for Mature Connection Solutions

      As the most widely used standard model, the DuPont 2.54 Series has become the preferred solution for electronic engineers due to its 2.54mm pitch. This model supports multi-specification configurations with 1 to 40 positions, is compatible with AWG 28-22 wires, and its rated parameters of 3A/250V can cover most industrial control scenarios. The pin diameter of the male connector is precisely controlled at 0.64mm, while the socket of the female connector adopts an optimized 0.8mm design. This not only ensures smooth plugging and unplugging but also achieves stable connection through interference fit, making it particularly suitable for scenarios requiring frequent plugging and unplugging, such as PLC control cabinets and home appliance power interfaces.

DuPont Locking

High-Strength Locking for

Extreme Anti-Disconnection Requirements

      For humid and dusty industrial scenarios, the Locking Series adopts a push-pull self-locking structure and an IP65 protection rating design, which can completely resist low-pressure water spray and dust intrusion. The built-in self-locking device ensures a stable connection state, and when combined with the anti-misinsertion key design, it completely eliminates the risk of incorrect insertion. This model still maintains good performance after 5,000 plug-in tests, and its wide temperature range of -45℃ to 125℃ allows it to adapt to special working conditions such as outdoor electrical cabinets and medical equipment disinfection environments.
