Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Power Transmission: Designed for wire-to-board connections with a rated current of 2A, enabling reliable power distribution in electronic systems.
  • Circuit Switching: Features two gold-plated metal pins for secure, low-resistance connectivity, ideal for switching or connecting circuits in electronic devices.

Key features

  • 1. Material Technology

    • With a durable thermoplastic body and gold-plated pins, ensure reliable insulation and corrosion resistance in diverse environments. The white plastic material (likely nylon/ABS) provides long-term stability, while gold-plated pins enhance conductivity and longevity compared to uncoated alternatives*.

  • 2. Interactive Design

    • With the compact 2.0mm pitch PH series design, achieve space-saving integration while maintaining secure connections. Its standardized form factor allows seamless compatibility with JST ecosystems, simplifying assembly in tight spaces* compared to bulkier connectors.

  • 3. Performance Parameters

    • With a 2A rated current capacity, handle low to medium power applications efficiently. This ensures stable power delivery for devices like home appliances or automotive systems, outperforming connectors rated for lower currents* in similar form factors.

  • 4. Scenario Solutions

    • Designed for power connections, this connector ensures stable power distribution in compact electronic devices. Its dual-core, two-pin configuration simplifies wiring for applications requiring straightforward power routing, ideal for both prototyping and commercial use*.

  • 5. Certification Standards

    • Complies with industry safety standards (e.g., RoHS compliance), ensuring reliable performance and environmental responsibility. While specific certifications may vary, JST’s reputation for quality aligns with global regulatory requirements* for electronic components.

Supplier's note

  1. Technical Breakthroughs:

    • The Pro model’s 3A rated current (50% higher than Base) enables support for high-power applications like industrial sensors.
    • 500V insulation voltage (Pro) ensures safety in high-voltage systems, exceeding standard 50V benchmarks.
    • -40°C to 105°C operating range (Advanced/Pro) accommodates extreme environments, such as automotive under-the-hood use.

  2. Version Selection Guide:

    • Base Model: Suitable for basic power connections in consumer electronics (e.g., LED lighting).
    • Advanced Model: Ideal for industrial IoT devices requiring wider temperature tolerance and moderate power handling.
    • Pro Model: Best for mission-critical systems (e.g., electric vehicle components) needing peak current capacity and reinforced insulation.

With the Pro model’s 3A rating, you can safely power high-demand devices without overheating. Its 500V insulation provides a 10x safety margin over Base models, ensuring reliability in harsh industrial settings.
