Taiss Ljc18A3-H-Z/Bx Proximity Switch 1-10Mm Sensor Switch Capacitance, Wire Product Details It is a component widely used in automatic control industry for detecting, controlling, and noncontact switching. When proximity switch is close to some target object, it will send out control signal. As it is capacitive type proximity switch, its detecting object target is not limited to only conductor, but also liquid and even powder things, like plastic, water, glass, oil, etc. It's widely used in machine, paper making, light industry for limiting station, orientation taking count, speeding trial ect. Product Name : Capacitive Proximity Switch;Switch Appearance Type : Cylinder Type Theory : Capacitance Sensor;Output Type : NPN NO(Normal Open);Diameter of Head : 18mm;Detecting Distance : 1-10mm Detecting Object : Metal or Nonmetal Material;Supply Voltage : DC 6-36V;Current Output : 300mA;Response Frequency : 100Hz Size : 7.5 x 4cm/3'' x 1.6'' (L*Max.
