Benefits introduce In Detail

Rugged housing specially designed and tested for the industrial automation sector

ifm’s pre-wired cylindrical proximity switches can reliably detect positions throughout the entire industrial automation process. The rugged metal housing is very suitable for demanding applications in fields such as robotics, packaging, assembly automation, and material handling.

The enhanced sensing range allows the proximity switch to be placed further away from the target, thereby reducing the possibility of damage caused by physical impact. The proximity switch uses a high-flexibility PVC cable that can withstand frequent movement.

Sensing range is determined by the physical size of the proximity switch

The strength of the radiated sensing field is determined by the size of the proximity switch core. A larger proximity switch also has a larger core, and therefore a longer sensing range.
