IFM Electronics IGT247 inductive proximity switch is indispensable for industrial usage. As compared to mechanical switches they offer almost ideal conditions: non-contact operation free from any wear and tear, high switching frequencies and accuracy. In addition, they are insensitive to vibration, dust and moisture. Inductive sensors detect all metals without contact. It is made of stainless steel 316L/1.4404 housing, stainless steel 316L/1.4404 active face, stainless steel 316L/1.4404 lock nuts.
