Solenoid Material
(OP)
Does anybody have experiences (good or bad) with a certain solenoid potting material? We are having issues with a nylon potting material melting and a polyurethane potting degrading. Other than potting compound are there any suggestions on waht may be causing the solenoid to reach such a high tempearture to fail? We have tried to replicate the failure and have not been successful.
Things that have been checked include wire varnish, potting material, installation.
Thank you!

RE: Solenoid Material
You have to reduce the heat.
You can improve the cooling of the solenoid, e.g. by blowing cool air across it,
OR, better,
by using a better driver circuit, that supplies full current to the solenoid during pull-in, and reduces the current when the solenoid has moved to its seat, during hold-in.
Speaking of the solenoid seat, be sure that the solenoid is not mechanically held off from being fully seated when energized; that will really mess them up.

RE: Solenoid Material
Is your solenoid AC or DC powered?
What job is it doing?

It is DC and is part of a hydraulic system; controlling flow to a variety of hydraulic equipment.
