de-gradation of latching solenoids?
de-gradation of latching solenoids?
(OP)
Hi,
We are thinking of using latching solenoids to divert water in domestic water pipes.
We see on datasheet that it takes one Watt of electrical power for 20ms to latch the solenoid.
-but after a few years of use, will it take more time to latch....eg , 1 Watt for 40ms?
here is the electrical part of the datasheet

I don't know if it's mechanical wear products jamming the mechanism or interfering with the magnetic circuit, or aging of the permanent magnets with the magnetic circuit open, or what, but they've never lasted for me, and their lifetimes were short enough that I had no interest in trying to improve them.
Always ended up with two-current drivers and regular solenoids; high current pull-in, low current hold-in.
Maybe they've improved. Maybe you'll get lucky. YMMV.
