Item Type: Proximity switch Product Model: LJ12A3-4-Z / AX Power Supply Voltage: DC6-36V Output Current: 300mA Detection Distance: Approx. 4mm / 0.16in 10% Opening Size: Approx. 120mm / 4.72in Power Cord Length: Approx. 1.12m / 3.67ft Output Form: DC three-wire normally open NPN NO Detection 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 0.04in Working Environment Temperature: -30 + 65 Housing Material: Brass nickel plated Detection Surface Material: ABS Applications: Security equipment, textile equipment, CNC machine tools, security inspection equipment, automated production lines, electronic machinery, etc.1Proximity 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. 2Supporting 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. 3When 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. 4Even 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. 5It 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
