Rotary limit switches series FCN - suitable for every purpose

The rotary limit switch of the FCN series has been used for many years for a wide range of applications. The switch, which has been introduced for many years, has proven itself especially in crane construction under the most difficult industrial conditions.

In general, the rotary limit switch is used for motion control of industrial machinery and industrial plants.

The revolutions of the shaft are transmitted to a cam switch mechanism, which actuates mechanical switching contacts. All variants of the switching contacts are designed as auxiliary current switches.

Reduction ratios of 1:7.5 to 1:550 are available for the FCN series rotary limit switches. The switch can be equipped with a maximum of 5 switching contacts. Each cam can be set individually to the desired position, thus allowing flexible definition of end positions and reference points.

To reduce abrasion and rusting, the transmission and guide shafts of the gear wheels are made of stainless steel.

All materials in direct contact with the environment are resistant to gases, oils and extreme temperature changes. The circumferential rubber seal provides optimum protection against dust and water, so that protection degree IP 65 can be easily achieved. The optimized interior allows quick and easy cabling.
