Solving Industrial Pain Points: Supu’s New Direct Crimp Connector Series

The new DL381, DL508, DP381, and DP508 series offer seamless compatibility, rapid installation, and robust safety features for automation, new energy, and smart home sectors.

Supu Electronics, a leading provider of industrial electrical connection solutions, today announced the launch of its latest Direct Crimp Connector Series (Models: DL381, DL508, DP381, DP508). Designed to address critical pain points in modern manufacturing, this new lineup delivers a superior balance of installation efficiency, mechanical stability, and cross-compatibility, setting a new benchmark for wire-to-board and wire-to-wire connections.

As industries accelerate towards automated production and higher safety standards, traditional connectors often fall short due to complex wiring procedures, poor interoperability, and limited adaptability. Supu’s new Direct Crimp Connector series directly tackles these challenges, offering a streamlined solution for engineers and manufacturers alike.

Key Features Driving Efficiency and Reliability

1. Rapid Installation for High-Volume Production
Engineered for speed, the new series utilizes an advanced cold pressure crimping technology. This eliminates the need for complex tools or soldering, significantly reducing assembly time. The connectors accommodate a wide range of wire gauges (0.08–2.2 mm²) with a standardized stripping length of just 4–5 mm, ensuring consistent, error-free termination and boosting overall factory throughput.

2. Versatile Configuration for Any Scenario
Flexibility is at the core of the design. Available in 3.81 mm and 5.08 mm pitch sizes, the series supports diverse circuit requirements:

• Pin Counts: Single-row (2~10P) and double-row (2×2~10P) options.
• Orientation: Both vertical and horizontal exit structures to fit compact PCB layouts.
• Complete Ecosystem: A full suite of matching wire plugs, sockets, and PCB headers ensures a seamless end-to-end connection system.
  
  

3. Uncompromised Safety and Durability
Safety remains paramount in harsh industrial environments. The housing is crafted from high-grade materials achieving a UL94-V0 flame retardancy rating. To prevent costly misconnection errors, the series features multiple anti-misinsertion coding options (0X, 0Y, XX, XY, YY). Furthermore, the design allows for easy visual inspection of wire insertion status, simplifying maintenance and reducing downtime risks.

4. Seamless Compatibility and Cost Efficiency
Supu’s new connectors are engineered for direct drop-in replacement. With electrical parameters matching mainstream industry competitors (3.81mm: 250V/8A; 5.08mm: 600V/8A), users can upgrade their systems without modifying existing equipment or PCB designs. This interoperability offers a cost-effective alternative without sacrificing performance or reliability.
