• Superior Hermetic Sealing: Full metal enclosure provides outstanding protection against environmental hazards, exceeding the performance of many commercial PCB Signal Relays and ensuring longevity in harsh conditions.
• Military-Grade Construction: Built as a robust Military Electromagnetic Relay, designed to withstand the vibration, shock, and temperature extremes common in aerospace applications.
• High-Density PCB Compatibility: Compact footprint makes it ideal for direct installation into existing PCB Board Relay layouts in avionics and UAV control systems.
• Reliable Long-Term Performance: Engineered for over 100,000 reliable switching cycles, reducing maintenance frequency and total lifecycle cost for critical systems.

Installation Procedure

1. Verify Original Part: Confirm the existing relay is a Russian P3C80 series with 27VDC coil.
2. System Safety: De-energize and secure the equipment according to safety protocols.
3. Careful Removal: Desolder or unplug the original P3C80 relay from its PCB footprint.
4. Precision Installation: ensuring perfect pin-to-pin alignment with the original orientation.
5. Secure & Validate: Solder connections securely and conduct comprehensive functional testing of the circuit.

Application Scenarios

This relay is essential for sustaining the operational readiness of systems dependent on Russian components. It delivers critical value by providing a reliable, high-quality alternative. Primary applications include: Legacy Russian/Soviet aircraft avionics and engine control upgrades, Military drone (UAV) flight control systems, Ground support and test equipment for Eastern Bloc platforms, and industrial control systems originally designed with P3C80 relays. It serves as a robust, sealed alternative where a standard DPDT 8Pin 27V Relay or Industrial Power Relay in a different package would not be compatible.

Quality Assurance

Manufactured in our ISO 9001 certified facility under a stringent quality management system. undergoes 100% electrical testing and batch-level validation to ensure performance meets or exceeds the original P3C80 specifications, consistent with the standards of our Military Metal Relay portfolio.

Customization Services

We offer OEM/ODM support for specialized projects. While designed as a direct replacement, customizations such as specific lead forms, marking, or additional environmental screening can be arranged for volume procurement, similar to services for our Polarized Relay JH-2S.

FAQ

Q: What is the primary application of this relay?
A: Its primary role is to maintain and upgrade systems originally designed with the Russian P3C80 relay, particularly in aviation, military, and related high-reliability fields.

Q: Can this relay be used in new designs not based on Russian equipment?
A: While its heritage is as a replacement, its military-grade construction and reliability make it a viable candidate for new high-reliability PCB Board Relay designs where its specific form factor and performance are required.

Q: Are samples available for compatibility verification?
A: Yes, we provide samples to qualified B2B clients for evaluation and testing against their specific P3C80 relays and application requirements.
