Military Metal Relay JRW-112MA TO-5: Replacement for Teledyne 411DD Series
Product Overview
The JRW-112MA TO-5 is a high-reliability Military Metal Relay engineered as a direct replacement for legacy Teledyne 411DD series components. This Aviation DC Relay combines form-fit-function compatibility with modern manufacturing excellence, providing a reliable upgrade solution for aging aerospace systems. With its military-grade TO-5 metal package and enhanced hermetic sealing, it serves as an ideal replacement for Aircraft Engine controls, drone electronics, and other critical applications originally designed with Teledyne 411 series components.
Product Features & Advantages
The JRW-112MA delivers enhanced performance while maintaining full 411DD compatibility:
- Direct 411DD Series Replacement: Form-fit-function compatible with Teledyne 411DD relays for seamless system upgrades.
- Military-Grade Hermetic Sealing: TO-5 metal-can sealing provides superior environmental protection for aerospace applications.
- Enhanced Electrical Performance: Lower contact resistance (≤50mΩ initial) and faster switching (≤4ms) than many legacy components.
- Dual Load Capability: Handles both power loads (1A at 28V DC) and sensitive signals (10-50µA at 10-50mV).
- Weight-Optimized TO-5 Package: Under 3 grams for minimal impact on aircraft and drone weight budgets.
- High-Reliability Construction: Modern materials and manufacturing processes provide extended service life.
- DPST Configuration: Suitable for applications requiring double-pole switching capability.
This relay complements YM's Military Electromagnetic Relay portfolio, sharing standards with our Aviation Latching Relay and Sealed magnetic Latching Relay solutions.
