Designed for areas where metal parts are unavoidably in contact with the proximity sensors, the new stailess steel housed Robust (R) series from ifm electronic features a long-lasting, anti-spatter coating. This coating is so good that weld spatter bounces off or can be wiped away with a finger. These new sensors are available in M12, M18 and M30 versions with sensing ranges of 4mm, 6mm and 12mm respectively. Thoroughly tested on an impact and abrasion simulator, the R series will last significantly longer than conventional sensors, and the coating will also withstand abrasion for longer than conventional coatings, according to ifm.
