Key Features & Advantages

Direct P3H Series Replacement: Exact form, fit, and function compatibility ensures seamless drop-in replacement in existing Russian-origin equipment.
Dual Voltage Flexibility: Available in both 12V and 27V coil versions to match various legacy system voltages, offering more versatility than single-voltage PCB Signal Relays.
Military-Grade Metal Housing: Full hermetic seal provides superior protection against moisture, vibration, and environmental contaminants, exceeding the durability of standard PCB Board Relays.
High Reliability Design: Built as a true Military Electromagnetic Relay with a minimum 100,000-operation lifespan for mission-critical circuits.
Fast & Precise Switching: ≤4ms response time meets the demands of modern avionics and UAV control systems while maintaining compatibility.

Installation Procedure

Identify Original Part: Confirm the system uses a Russian P3H series relay and determine its coil voltage (12V or 27V).
Select Correct Model: Order the JQX-6M with the matching coil voltage (12V or 27V).
System Preparation: Safely power down the equipment before starting replacement.
Replacement: Carefully remove the old P3H relay and install the JQX-6M, ensuring identical pin orientation.
Verification: Restore power and conduct functional tests to validate proper switching operation.

Application Scenarios

This relay is indispensable for maintaining and upgrading systems of Russian origin. It delivers critical value by providing a reliable, available alternative. Key applications include: Legacy Russian/Soviet aircraft avionics upgrades, Drone and UAV control systems based on older designs, Military ground vehicle electronics, Industrial control systems using P3H series relays, and any application where a robust, hermetically sealed DPDT 8Pin 27V Relay equivalent is required. Its reliability makes it suitable where a standard Industrial Power Relay might not meet the environmental or form-factor requirements.

Quality & Compliance

Manufactured in our ISO 9001 certified facility under a stringent quality management system. The JQX-6M is produced with processes designed to meet the reliability standards expected in military and Aviation Applications, consistent with our full range of Military Metal Relay products.

Customization Options

FAQ

Q: What is the difference between JQX-6M and JQX-6MT?
A: They are functional equivalents with potential minor internal or marking variations. Both are designed as P3H replacements. Specify your required coil voltage (12V or 27V) when ordering.

Q: Is this relay interchangeable with all P3H variants?
A: It is designed to replace common P3H series relays (e.g., P3H34). Always verify pinout and dimensions against your specific P3H variant datasheet.

Q: Can I use the 27V version in a 24V system?
A: The relay is designed for 27V nominal operation. Using it in a 24V system may affect pull-in and dropout characteristics. For optimal performance, use the voltage specified for your system.

Q: Are samples available to test compatibility?
A: Yes, we provide samples to qualified B2B customers for evaluation and verification against their specific P3H relay and application.
