Product Features & Advantages
This relay is designed to outperform standard PCB Signal Relays and Automotive Relays in harsh environments. Its core advantages stem from a military-spec design philosophy:
- Hermetic Metal Sealing: Full metal-can weld sealing ensures protection against moisture, dust, salt spray, and other contaminants, guaranteeing stable performance from high altitudes to ground-level humidity. This Military Metal Sealing is the gold standard for long-term reliability.
- Military & Aviation Grade Construction: Built to withstand extreme vibration, mechanical shock, and wide temperature fluctuations encountered in aviation and drone operations.
- High-Speed Switching: With an action time of ≤4ms and release time of ≤4ms, it provides rapid response for critical control circuits in flight systems.
- Ultra-Low Power Consumption: Coil power consumption is optimized between 0.3W and 0.43W, making it suitable for power-sensitive avionics and portable military equipment.
- Dual Contact Performance: Reliably handles both standard resistive loads (1A, 28V DC) and low-level signal loads (10-50µA, 10-50mV), offering versatility within a single, robust package.
Unlike many commercial relays, the JX-3C is part of our specialized family that includes Aviation Latching Relay and Polarized Relay JH-2S solutions, sharing the same commitment to extreme-environment performance.

Application Scenarios
The JX-3C relay is a critical component in systems where reliability is paramount. Its primary application is in aerospace and defense, but its robustness extends to other demanding fields.
- Aviation & Aerospace: Flight control systems, Aircraft Engine monitoring and maintenance units, landing gear control, and cockpit instrumentation. Its sealing makes it ideal for both pressurized cabin and engine-adjacent environments.
- Unmanned Aerial Systems (Drones): Power distribution modules, payload (camera/sensor) switching, and communication system control in military and industrial-grade drones.
- Military Ground Vehicles & Communications: Ruggedized electronic systems, encrypted comms equipment, and mobile command unit controls.
- High-Reliability Industrial: While it shares the robust DNA of our Industrial Power Relay line, the JX-3C is specified for niche industrial applications where environmental factors rule out standard components, such as in maritime or remote telemetry systems.
Production & Quality Assurance
Every JX-3C relay is born in YM's controlled manufacturing environment. Our process ensures the consistency demanded by aviation and military specifications.
- Precision Component Fabrication: Critical parts are machined to micron-level tolerances using advanced CNC equipment.
- Cleanroom Assembly: Assembly of the sensitive contact and magnetic systems takes place in a temperature and humidity-controlled cleanroom to prevent contamination.
- Laser Hermetic Sealing: The final, critical step is automated laser welding of the metal casing, performed in an inert atmosphere to achieve the specified leak rate of ≤10⁻³ Pa·cm³/s.
- 100% Automated Testing: Each unit undergoes a full battery of tests, including contact resistance, operate/release time, dielectric strength, and seal integrity (helium leak testing).
- Lot Traceability: Full material and process traceability is maintained for every production batch, a non-negotiable requirement for our Military Electromagnetic Relay products.

Frequently Asked Questions (FAQ)
Q1: Is the JX-3C a latching or non-Latching Relay?
A: The JX-3C (RG4.566.007) is a standard electromagnetic, non-latching relay. It requires continuous coil voltage to maintain the switched state. For applications requiring zero holding power, please inquire about our Aviation Latching relay solutions.
Q2: Can this relay be used as a direct replacement for part number XYZ in an existing avionics system?
A: The JX-3C may be a form-fit-function equivalent for many military and aviation relay footprints. However, for direct replacement in certified systems, a formal cross-reference and qualification process is required. Our engineering team can provide detailed comparison data to support your qualification efforts.
Q3: What is the key difference between the JX-3C and a standard PCB Board Relay?
A: The primary differences are the hermetic metal seal and the military-grade construction. A standard PCB Board Relay is typically housed in plastic and is not designed to operate reliably under the extreme vibration, thermal cycling, and contaminant exposure that the JX-3C is built to endure.
Q4: Do you offer customization on the coil voltage or pin configuration?
A: Yes. As part of our commitment to serving OEM/ODM partners, YM offers customization options for this platform, including specific coil voltages, special pin coatings, and modified termination styles for high-volume projects. Contact our sales team to discuss your requirements.
Q5: How does the sealing performance compare to epoxy-potted relays?
A: Metal hermetic sealing provides superior long-term stability compared to epoxy potting. Epoxy can absorb moisture over time and may outgas in a vacuum, potentially affecting internal components. The laser-welded metal seal of the JX-3C creates a permanent, impermeable barrier, offering definitive protection for the relay's operational lifetime.
