SICK Non-contact safety switches

Non-contact safety switches

Low-maintenance, intelligent solutions

Non-contact safety switches are ideal in applications where precise guidance of guards is difficult. Due to their design, they are extremely long-lasting devices that require minimal maintenance. In addition, they are resistant to shock and vibrations and offer a high level of prevention against tampering. Our range of non-contact safety switches includes magnetic, transponder and inductive safety switches. Rectangular and cylindrical types are available for each sensor principle.
