Product Features & Competitive Advantages

1. Ultra-Compact DPDT Design: Provides two independent changeover contact sets in a small footprint, ideal for dense PCB layouts and control modules.
2. Low Coil Power Consumption: 0.3–0.43W enables direct drive from microcontrollers and logic gates, reducing power supply demands.
3. Fast Switching Speed: ≤4ms operate/release time ensures real-time response for safety interlocks and solenoid drivers.
4. Excellent Contact Stability: Maintains low and stable contact resistance throughout 100,000+ operations, critical for low-level signal switching.
5. Hermetic Sealing Option: Leakage rate ≤10⁻³ Pa·cm³/s protects contacts from moisture, dust, and corrosive gases – suitable for under-hood and outdoor installations.
6. Versatile Compatibility: Works seamlessly with Aviation Microswitch, Hydraulic Circuit Breaker, and Aviation Temperature Sensor in integrated vehicle and industrial systems.

Installation & Wiring Steps

1. Pin Configuration Verification: Identify coil terminals (typically pins 1 and 10 or as per datasheet) and contact terminals (common, NC, NO for each pole).
2. PCB Mounting: Insert relay into pre-drilled PCB holes. Ensure correct orientation (marked by polarity dot or notch). Solder at ≤350°C for ≤3 seconds per pin.
3. Coil Connection: Apply 12V DC to the coil terminals. Do not exceed 13.2V (10% tolerance).
4. Load Wiring: Connect loads to COM/NC/NO terminals as required. For DPDT, each pole can control independent circuits (e.g., one for a pump, one for a warning light).
5. Functional Test: Energize coil and verify continuity between COM and NO; de-energize and verify continuity between COM and NC. Measure contact resistance (<50mΩ).
6. Integration with Sensors: For automated control, pair with Military Pressure Sensor or Aviation Haulage Pressure Sensor for pressure-based switching.
