Mr. Steve Robinson;


This email is in response to your request about ROHS and PN WM35A-120.


The WM35 is a mercury displacement relay.  It contains mercury and will not be ROHS compliant.  The properties of mercury in the part give it characteristics far superior to any non-mercury part.  Struthers-Dunn is presently working on alternatives for the future that are ROHS compliant but nothing to date has similar performance..
