Product Features & Competitive Advantages

1. Dual Contact (2C) Design: Provides two independently switched circuits (DPDT), enabling control of multiple loads or changeover functions from a single coil – ideal for complex control logic.
2. Ultra-Low Coil Power Consumption: Consumes only 0.3-0.43W, reducing heat generation and enabling direct drive from logic circuits (PLC, microcontroller) without additional drivers.
3. High Switching Speed: ≤4ms operate/release time ensures fast response for safety interlocks and real-time control systems.
4. Excellent Contact Stability: Maintains low and consistent contact resistance throughout 100,000+ operations, ensuring signal integrity in critical measurement circuits.
5. Hermetic Sealing Option: Leakage rate ≤10⁻³ Pa·cm³/s protects contacts from dust, moisture, and corrosive atmospheres – suitable for harsh industrial and military environments.
6. Wide Compatibility: Designed to work seamlessly with other YM components such as Aviation Microswitch, Hydraulic Circuit Breaker, and Aviation Temperature Sensor in integrated systems.

Installation & Operation Steps

1. Pin Configuration Check: Refer to the datasheet for coil terminals (typically pins 1-2) and contact terminals (common, NC, NO for each pole). Verify the 2C arrangement matches your circuit diagram.
2. PCB Mounting (for PCB version): Insert relay into pre-drilled PCB holes. Ensure proper orientation. Solder with temperature-controlled iron (≤350°C, <3 seconds).
3. Socket Mounting (for plug-in version): Use a compatible relay socket (e.g., PF083A). Secure relay firmly into socket until latch clicks.
4. Coil Voltage Verification: Apply rated coil voltage (e.g., 24V DC) and listen for a distinct click, indicating armature pickup.
5. Contact Wiring: Connect load circuit to common (COM) and normally open (NO) or normally closed (NC) contacts as required. For 2C, each pole (two separate contact sets) can control independent loads.
6. Testing: Energize coil and verify continuity between COM and NO; de-energize and verify continuity between COM and NC. Measure contact resistance to confirm ≤50mΩ.
7. Integration with Sensors: For systems requiring feedback, combine relay with Aviation Pressure Sensor or Military Pressure Sensor for automated protection.
