Reed Relays Q & A
Q: What's the typical lifespan of a reed relay?
A: Quality relays can last for 100 million operations or more under proper conditions.
Q: How do reed relays compare to solid-state relays?
A: Reed relays offer better isolation and lower contact resistance, while solid-state relays have no moving parts.
Q: What's the minimum order quantity when buying from China?
A: MOQs vary but typically start at 100-500 pieces for standard models.
Q: Can reed relays handle high voltages?
A: Special high-voltage models are available that can switch several kilovolts.
Q: How sensitive are reed relays to mechanical shock?
A: While robust, excessive vibration or shock can affect performance - consider mounting orientation.
