1、Proximity switch is a kind of switch-type sensor that is non-contact switch, which has the characteristics of travel switch and micro-switch with reliable action and stable performance. 2、Supporting fast frequency response for long application life, the switch has strong anti-interference ability, etc. And it also has the characteristics of waterproof, shockproof, corrosion resistance, etc. 3、When the metal detector is close to the sensing area of ​​the switch, the switch can be contactless, no pressure, no spark, which can quickly send out electrical instructions and accurately reflect the position and travel of the movement mechanism. 4、Even if it is used for general travel control, its positioning accuracy, operating frequency, service life, ease of installation and adjustment, and ability to apply to harsh environments are incomparable by general mechanical trip switch. 5、It is widely used in machine tool, metallurgy, chemical, light textile and printing industries. Furthermore, it can be used for limiting, counting, positioning control and automatic protection in automatic control systems. 10 x Proximity Switch Item Type: Proximity switchProduct Model: LJ12A3-4-Z / AXPower Supply Voltage: DC6-36VOutput Current: 300mADetection Distance: Approx. 4mm / 0.16in ± 10%Opening Size: Approx. 120mm / 4.72inPower Cord Length: Approx. 1.12m / 3.67ftOutput Form: DC three-wire normally open NPN NODetection Object: Magnetic metal (detection distance is reduced while detecting non-magnetic metal)Standard Detection Object: Iron, approx. 12 x 12 x 1mm / 0.47 x 0.47 x 0.04inWorking Environment Temperature: -30— + 65 ℃Housing Material: Brass nickel platedDetection Surface Material: ABSApplications: Security equipment, textile equipment, CNC machine tools, security inspection equipment, automated production lines, electronic machinery, etc.
