LEFOO LF08 Air Conditioning Refrigeration Pressure Switch Automotive Pressure Switch With CE Approved

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Pressure Monitoring & Control: Designed to monitor and regulate pressure levels in air conditioning, HVAC, and refrigeration systems, ensuring optimal performance and safety.
  • Automotive & Industrial Use: Equipped with a SPDT contact arrangement and copper material, it triggers automatic responses (e.g., shutting off systems or activating alarms) when pressure exceeds or drops below predefined thresholds.

Key features

  • 1. Corrosion-Resistant Copper Material Technology

    • With a corrosion-resistant copper body, ensure durability in harsh environments such as HVAC systems and refrigeration units. This material outperforms plastic-based switches in longevity under high humidity or chemical exposure*.

  • 2. High Current Capacity for Heavy-Duty Applications

    • With a 15A maximum current rating, handle demanding automotive and industrial systems more reliably than standard 10A pressure switches*. Ideal for applications requiring robust power management.

  • 3. Versatile Media Compatibility

    • Compatible with water, air, oil, and transmission/motor oils, this switch adapts to diverse media types, making it suitable for automotive cooling systems, HVAC refrigeration, and industrial fluid applications.

  • 4. CE-Certified Safety and Compliance

    • With CE certification, meet EU safety and quality standards for automotive and commercial use, ensuring regulatory compliance and enhanced user confidence.

  • 5. SPDT Contact Arrangement for Flexible Circuit Control

    • Using an SPDT (Single Pole Double Throw) contact design, enable complex circuit configurations for multi-functional systems, unlike basic SPST switches limited to on/off control*.

  • Notes:

    • The product’s modular design (implied by standard G1/4 and G1/8 threads) and durability align with industrial and automotive needs, though not explicitly highlighted due to formatting constraints.

Supplier's note

  1. Technical Breakthroughs:

    • Copper Construction: Reduces thermal expansion risks, ensuring stable performance in oil-based systems.
    • SPDT Contact Arrangement: Enables bidirectional control, ideal for complex HVAC systems.
    • CE Certification: Streamlines compliance for EU automotive and industrial applications.

  2. Version Selection Guide:

    • Base Model: Best for standard automotive or HVAC systems requiring 15A capacity (e.g., passenger vehicle AC units).
    • Advanced Model: Suited for heavy-duty industrial refrigeration or oil transmission systems needing higher current (20A) and wider temperature tolerance.
    • Pro Model: Optimal for extreme environments (e.g., commercial trucks or offshore machinery) with ultra-precise pressure control (±1%) and IP67 waterproofing.

With the Pro version’s IP67 rating, you can deploy it in marine or outdoor systems where water exposure is common. Its 25A capacity paired with ±1% accuracy ensures safe, reliable operation even under peak loads.
