Rotary Limit Switches
Rotary limit switches are designed for use in yaw and electrical pitch systems.
In yaw systems the rotary limit switches are used as a safety device preventing the nacelle to turn too many revolutions and damage cables connecting tower and nacell.
The rotations of the shaft are transferred to a cam controller through which mechanical switching contacts are actuated. All variants of the switching contacts are available as auxiliary power switch.
A wide range of rotation ratios are awailable. The switches can be equipped with up to 4 switching contacts. Each cam can adjust individually to the desired position and allows the flexible setting of end positions and reference points.
Transmission and gear driving shafts are made of stainless steel to prevent oxidation and wear.
All materials in direct contact with the environment are resistant to atmospheric agents, oils and extreme temperature changes. The rubber gaskets ensure optimal protection against dust and liquids, thus the protection degree of IP 65 is easily reached. The optimized internal space allows the make of all connections easily and quickly.
