YM introduces the JZC-4M, a high-reliability Military Metal Sealing Relay specifically engineered as a direct, performance-matched replacement for CII HFC series relays. Available in 12V, 24V, and 27V coil configurations, this hermetically sealed Aviation DC Relay delivers military-grade durability and precision switching for critical aerospace, defense, and industrial control applications. Designed as a drop-in PCB Board Relay solution, it ensures seamless legacy system maintenance and enhanced reliability in demanding environments.
The JZC-4M serves as a critical component in mission-critical systems where reliability is paramount:
YM manufactures the JZC-4M series under stringent quality control protocols aligned with military and aerospace reliability requirements. Our production processes incorporate testing methodologies that validate performance against the original HFC specifications while often exceeding them in key durability and environmental resilience metrics.
Beyond standard replacements, we offer tailored solutions for unique requirements:
A1: Yes, the JZC-4M is specifically engineered as a direct replacement for CII HFC series relays. It matches the physical dimensions, pin configuration, and key electrical parameters, enabling seamless integration without circuit modifications.
A2: Our JZC-4M offers fresh production with consistent quality, modern materials, and traceable manufacturing. NOS components may suffer from age-related degradation, while our relays provide predictable performance and ongoing technical support.
A3: While Solid State Relay technology offers advantages in certain areas (cycle life, vibration resistance), the JZC-4M provides superior galvanic isolation, lower on-state resistance, and immunity to voltage transients. The choice depends on specific application requirements.
A4: Yes, the JZC-4M's reliability and environmental resilience make it suitable for auxiliary control circuits in New Energy Relay applications, including battery management systems, charging infrastructure, and renewable energy controls.
A5: We maintain flexible production capacity to support both small replacement batches and large-volume orders. Standard variants typically have 4-8 week lead times with competitive MOQs. Contact us with your specific requirements for detailed quotations.
