The MFT and MGT sensors from ifm electronic use GMR magnetic technology (the same as in a pc hard drive) to detect a magnetic target at long ranges.
This development by ifm sees the sensor incorporated into a completely sealed all-round stainless steel housing in standard M12 (MFT) and M18 (MGT) sizes, and will be of particular interest to the food industry
Sensing typically 60 to 70mm (depending on the magnet used and how it is fitted), the ranges fit neatly between inductive sensors and photocells – in harsh environments. Full-metal magnetic sensors designed for use in the food industry feature IP ratings of 68 and 69K, will operate in temperatures from 0 to 100°C.
