Limit Switch HER
APPLICATION
The Kiepe limit switch HER made of aluminum alloy 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 10° – can be adjusted between 5° and 35°.
The roller lever with ball bearing is infinitely adjustable on the shaft. The positive making switching elements are cam operated. The self-cleaning of the contacts by mechanical grinding allows the use in low voltage applications (PLC- or BUS-control)
