The XS630B1PBL2 from Schneider Electric / Telemecanique is a general purpose OsiSense XS inductive proximity sensor XS6 for non contact sensing of metal objects. It features best in class quality and immunity to harsh industrial environments. An inductive proximity sensor is comprises an oscillator whose windings constitute sensing face. An alternating magnetic field is generated in front of these windings. When a metal object is placed within magnetic field generated by sensor, the resulting currents induced form additional load and oscillations cease. This causes output driver to operate and depending on sensor type (NO or NC output signal). This sensor enables detection without physical contact of metals. It's range of applications includes monitoring position of machine parts (cams, end stops), counting presence of metal objects. It also used in assembly machines, machine tools, machining, packaging, materials handling, conveying, mobile equipment, food and beverage industry.
