13 Component Specification
Yoke Electrolytic zinc-coated steel sheets *(some are with haxavalent chromium free zinc plating.)
Yoke Cover Haxavalent chromium free zinc plating.
Plunger Fluoroplastic coating (open frame solenoids), Nickel plating (keep solenoids)
Plunger Stopper Haxavalent chromium free zinc plating or Nickel plating.
*The fracture surface of Yoke with electrolytic zinc-coated steel sheets is not coated for dust-proof, causing rust. But, there is no impact to solenoid operation characteristics. If preferred, yoke with haxavalent chromium free zinc plating is available.
