Frequently Asked Questions (FAQ)

Q1: What is the difference between metal sealed and epoxy sealed relays?

A: Metal sealed relays like the JMC-10M offer superior long-term reliability. The welded metal enclosure provides a true hermetic seal that doesn't degrade with age, temperature cycling, or exposure to chemicals. Epoxy seals can absorb moisture, experience thermal stress cracking, and may outgas contaminants over time. For applications requiring decades of reliable service in harsh environments, metal sealing is the preferred choice.

Q2: Can the JMC-10M be used in AC applications?

A: The JMC-10M is specifically designed and rated for DC applications. Its arc suppression and contact materials are optimized for DC switching characteristics. Using it for AC applications may result in reduced performance and shorter lifespan. For AC applications, we recommend consulting our AC-rated relay series.

Q3: What is the expected service life in industrial applications?

A: In typical Industrial Power Relay applications, the JMC-10M can provide 10+ years of reliable service when operated within specifications. The actual lifespan depends on:

• Switching frequency and duty cycle
• Load characteristics (resistive vs. inductive)
• Environmental conditions (temperature, vibration)
• Proper circuit protection implementation

Q4: How does this relay compare to solid-state alternatives?

A: The JMC-10M offers advantages over Solid State Relay for Drone and other SSR applications in several areas:
