The new driver rotary limit switch series FRS stands out especially by its small dimensions. As the smallest driver rotary limit switch from our various series the FRS can be used where space is a critical size.

 

In general the rotary limit switch is used to control the movement of industrial machinery and systems. 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.

 

For the rotary limit switches series FRS rotation ratios ranging from 1:15 to 1:175 are available. The switch 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.
