Benefits introduce In Detail

Flexible and fast installation

The three-piece solution enables flexible and fast installation. ifm has developed accessories and connectors that simplify the installation process for inductive proximity switches. By using ifm efector quick-disconnect cable connectors that support plug-and-play wiring, the total installation time for the proximity sensor can be further reduced.

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.
