Gear Limit Switches
The gear limit switches with transmission ratios from 5:1 to 15:1 are modular switching devices for the pivot range limitation. The positively activated contacts are actuated by means of two infinitely variable cam discs over a zero-play toothed gear drive realized by means of a pretensioned twin gear wheel. Encoders or potentiometers can be optionally flange-mounted on the metal drive shaft. This version, which is installed in a powder-coated steel housing and adapted to the size of the limit switch, has been field-proven over many years of use in lifting equipment applications.
