How to use a boost cap to kickstart a relay with low voltage

I would make a circuit board which generates and fills the supercap, and wire the relay to that. The trigger fires it. Just like a camera flash unit, you have to wait till the cap is charged to fire it. Your trigger would be electronic.

Your cycle repeat rate takes the hit, but the store and fire PCB charge time sets that. The relay would have to be able to hold or latch on its own until released, however.

You could simply use a SSR too. or make an SSR.

Or make a direct DC to DC point of use converter that converts your sagged voltage to that required by the relay.

That is just stupid. Any hard surface yields an abrupt signature with a hign, fast slew rate toward infinite Gs. Theoretically.

Pool balls are solid objects, right?

Sorry, but a one inch drop does not yield a 10G shock into an object.

If you want to look at vibe prcedures AND specs, look at hard drive manufacturers.

They take over 40Gs when not under power.

They tell you exactly how they get their figures.

Good points. I am just amazed that Omron that makes relays for a living doesn't have answers to this important spec

They are too expensive, need buttom dollar here as usual

Cheers
