Feature:1. Proximity switch is a position switch that can be operated without making direct mechanical contact with moving parts.2. When an object approaches the sensing surface of the switch to an operating distance, it does not require mechanical contact and no pressure to make the switch actuate, thereby driving DC electrical appliances. Or provide control instructions to a computer (plc) device.3. Proximity switch is a kind of switch-type sensor (that is, non-contact switch). It has the characteristics of travel switch and micro switch. It also has sensing performance, reliable operation, stable performance, fast frequency response, long application life, and strong anti-interference ability, etc., and has the characteristics of waterproof, shockproof, corrosion resistance.4. Proximity switches, also known as non-contact proximity switches, are ideal electronic switch sensors. When the metal detector is close to the sensing area of ​​the switch, the switch can be contactless, no pressure, no spark, and quickly send out electrical instructions, accurately reflecting the position and stroke of the motion mechanism, even for general stroke control, it has good positioning accuracy, operation frequency, service life, ease of installation and adjustment, and ability to adapt to harsh environments.5. Widely used in machine tool, metallurgy, chemical, light textile and printing industries. It can be used as limit, counting, positioning control and automatic protection in the automatic control system.Specification:Item Type:Proximity SwitchModel:LJ8A3-2-Z/BYDetection Distance: 2mm ± 10%Thread Size: M8Mounting Aperture: 8mmLag Distance: Less Than 10% of The Detection DistanceDetection Object: Magnetic Metal (Detection Distance is Reduced When Detecting Non-Magnetic Metal)Response Frequency: DC: 0.5kHz AC: 25HzCurrent Consumption: N.P Type: 13mA or Less, D Type: 0.8mA or Less, A Type: 1.7mA or LessControl Output: N.P Type: 300mA or Less, D Type: 200mA or Less, A Type: 400mA or LessCircuit Protection: N.P.D Type: Reverse Connection Protection, Surge Absorption, Load Short Circuit Protection, Type A: Surge AbsorptionAmbient Temperature and Humidity: During operation and storage: -30 ~ +65℃(No icing or frosting), during operation and storage: 35-95% RH Effect of Temperature: Temperature Range -30~+ 65 ℃, + 23 ℃, within ± 15% detection distanceTemperature Range: -25~+ 60 ℃, +23 ℃, within ± 10% detectionInsulation Resistance: Above 50MΩ (DC500 Megohmmeter) between charging part and caseHousing Material: Nickel-plated brass Detection Surface Material: ABS.Package List:10 x Proximity Switch
