Innovations
made in Germany
We offer high quality, reliable and durable switchgear for industrial plants and conveyor technology.
Our highlights
Long-life switches for use in heavy-duty applications and under the most extreme operating conditions to monitor and ensure the safety of belt conveyors and equally of the persons involved.
>> Misalignment Switches
>> Pullcord Switch
>> Material Flow Control
Limit switches for safely shutting off the lifting movement of the crane hook and the horizontal direction of movement of the crane in end positions to prevent accidents.
Safe and controlled operation of locks, weirs, dams, flood protection facilities and of bascule bridges and ship lifts. Shutdown in emergency end positions.
For use in flammable atmospheres and thus potentially explosive atmospheres. Tested according to ATEX and, depending on the variant, approved up to mining areas.
