The JQX-5M (Military Part Numbers: RJ4.523.049 for 27VDC and RJ4.523.108 for 12VDC) is a standard-issue Military Metal Sealing Relay engineered for the most demanding aviation and defense applications. Featuring a rugged military-grade metal enclosure and dual voltage options, this Aviation DC Relay provides a reliable, long-life switching solution for critical control systems in drones, aircraft, and military vehicles.

This relay is a workhorse component designed for high-reliability environments. It delivers value through standardized availability and robust performance. Key applications include: Military vehicle electronic control units (ECUs), Drone autopilot and flight control systems, Aircraft instrumentation and sensor interfaces, Ground support equipment, and Industrial automation requiring a hermetically sealed DPDT 8Pin 27V Relay equivalent. Its construction makes it suitable where environmental factors rule out standard Industrial Power Relays.
Manufactured in our ISO 9001 certified facility under a rigorous quality management system. Each JQX-5M relay undergoes 100% electrical testing and batch-level environmental validation to ensure it meets the stringent performance standards expected for Military Metal Relay applications.
We offer comprehensive OEM/ODM support. While the JQX-5M is a standard component, customizations such as specific lead configurations, marking, or enhanced screening tests can be developed for volume procurement projects, similar to services for our Polarized Relay JH-2S.
Q: What is the difference between RJ4.523.049 and RJ4.523.108?
A: The primary difference is the coil voltage. RJ4.523.049 is for 27VDC systems, and RJ4.523.108 is for 12VDC systems. All other specifications are identical.
Q: Are these part numbers recognized in military procurement systems?
A: The RJ4.523.xxx numbering format follows a common military/national stock numbering convention, facilitating identification and sourcing within defense logistics networks.
Q: Can the 12V version be used in a 24V system with a resistor?
A: No. For reliable and predictable operation, you must use the relay version that matches your system's nominal coil voltage. Using a series resistor is not recommended for critical applications.
Q: Is this relay suitable for New Energy applications like battery management?
A: Its reliability and sealing make it potentially suitable for certain demanding New Energy Relay applications, provided the voltage, current, and environmental specifications align with the requirements.
