- I recently acquired some coaxial relays very similar to the DK-60 type (but there are no markings on them). They have 12VDC coils. I was surprised to find that although these relays "make" quickly (n

- I not being a relay expert either, I wonder if the slow brake is due to some sort of residual "permanent" magnetism on the core of the relay??? Maybe just a demagnetizing might help the problem??? Ph

- If you can read through the coil the same resistance in both directions (checking for internal diodes), why not try reversing the DC polarity to the coil? That should help with "stiction" or whatever

- Hi All If I recall correctly, it is possible to make relays with a very long drop out delay. It is obviously related to the design of the magnetic field and I seem to remember involves the use of bra

- Hi Scott NX7U - You have indicated that the release times indicated are after 0vdc; so, the following obviously won't be the answer if you are getting an accurate 0vdc measurement at the coils. Anywa
