FAQs

Q: Is this reed relay suitable for high-voltage switching?
A: No, its maximum switching voltage is 100VAC/VDC. Exceeding this may damage contacts.

Q: Can I use this with a 3.3V logic controller?
A: The must-operate voltage is 3.8VDC. For 3.3V systems, select a relay with lower coil voltage specifications.

Q: Why choose reed relays over solid-state alternatives?
A: Reed relays provide galvanic isolation, zero off-state leakage, and no voltage drop – critical for precision measurement circuits.

Q: This part is marked obsolete. Can PCX still supply it?
A: Yes! PCX specializes in sourcing discontinued components. Contact us for availability of end-of-life parts.

Q: Does the electrostatic shield require grounding?
A: Yes, connect the shield terminal to ground for effective EMI/RFI protection.

Q: What’s the expected mechanical lifespan?
A: Typical reed relays exceed 1 billion operations due to contactless actuation. Actual lifespan depends on load conditions.
