1、When the metal detector is close to the sensing area of the switch, the switch can quickly issue instructions and accurately reflect the position and stroke. 2、Capacitive proximity switches can not only detect metals, but also plastics, glass, water, oil and other substances. 3、The operating distance of the proximity switch is adjustable to suit different detection objects. 4、DC 3-wire NPN NO output, the sensing distance is 2mm, which can quickly and accurately sense objects and perform detection. 5、Used for multiple controls of machine tool limit, detection, counting, speed measurement, positioning and signaling, etc. Item Type: Metal Induction Switch Product Model: LJ12A3-2-Z/BX Detection Distance: Approx. 2mm / 0.1in Detection Object: Metal object Sensor Diameter: Approx. 12mm / 0.5in Output Mode: NPN NO DC 3-wire Sensing Direction: Front Output Current: 300MA Cable Length: Approx. 1.2m / 3.9ft Product Size: Approx. 56 x 12mm / 2.2 x 0.5in How to Use: Capacitive proximity switches can not only detect metal, but also plastic, glass, water, oil and other substances. Due to the difference in conductivity, dielectric constant, water absorption, and volume of various detected substances, the corresponding detection distance is also different. For grounding The metal can get the maximum detection distance. 10 x Metal Induction Switch
