Frequently Asked Questions (FAQ)
- Q: What distinguishes this as an "Aviation DC Relay" versus standard industrial relays?
A: Aviation relays like the JRC-9M feature superior sealing (≤10⁻³ Pa·cm³/s), faster switching times (≤3ms action), extended life (100,000+ cycles), and are tested for performance under low-pressure conditions (250Vr.m.s. at reduced pressure) - all critical for airborne applications.
- Q: Can this relay replace a Polarized Relay JH-2S in existing designs?
A: Not directly without design review. The JRC-9M is a non-polarized DPDT relay. Compatibility depends on electrical characteristics, pin configuration, and application requirements. Our engineering team can assist with replacement analysis.
- Q: How does the weight specification (<3g) benefit aircraft applications?
A: In aviation, weight reduction directly impacts fuel efficiency and payload capacity. The lightweight design helps minimize overall system weight while maintaining high reliability.
- Q: Is this relay suitable for high-vibration environments found in aircraft engines?
A: Yes. The military-grade metal housing and robust internal construction provide excellent resistance to vibration and shock, making it suitable for engine-mounted electronics and other high-vibration applications.
- Q: What quality documentation accompanies these relays?
A: We provide comprehensive documentation including test reports, material certifications, and traceability records. For aviation customers, we can supply additional documentation as required by industry standards.
