The limit switch RES made of rigid cast iron has been designed for a maximum of safe operation under severe conditions to become installed in any bulk handling system (e. g. in open pit mines).
All external parts are either of stainless steel or have been specially plated.
The trip points - both preset at 15° – can be modified by breaking out a cam to get a pre-alarm position at 15° and define cut-out at 45° excursion.
The roller lever with ball bearing is adjustable in steps of 12° on the shaft. Due to the toothing of shaft and roller lever (positiv drive) and the positiv making switching elements the RES meets the requirements for safety applications.
