FA Product

Metal Pass Sensor

LMS Series

It is the metal passage confirmation sensor that detects minute metal.
It has the outstanding environment-proof nature. (IP67)

The metal foreign substance detection to a granular material, food, etc. and the needle mixing detection to cloth products are possible.Moreover, supply of a screw and metal parts, discharge detection, etc. can be performed easily.
