Feature:1. CORROSION RESISTANT MATERIAL: The proximity switch has a copper alloy threaded housing that is corrosion resistant and 1.4meter long, easy to use2. FAST AND ACCURATE: The inductive proximity sensor switch has a built in intelligent induction chip, which is interference resistant and generates induction when it is close to metal objects for accurate detection3. LED WORKING INDICATOR: Proximity switch has an action indicator. When sensing a metal object, light on is normally open, light off is normally closed, which makes the operation easier and clearer4. HIGH EFFICIENCY: Inductive proximity switch detector is waterproof and oil proof, with IP67 protection grade, bring fast response frequency and high efficiency5. APPLICABLE SCENARIO: Inductive proximity switch can be used for automatic production line, mechanical equipment, security equipment, textile equipment, CNC machine tools, monitoring equipmentSpecification:Item Type: Inductive Proximity SwitchVoltage: 6-36VDCOutput Form: NPNContact Type: NO and NCCurrent: 200mADetection Distance: Approx. 2mm / 0.08inProbe Size: Diameter: Approx. 12mm / 0.47in, Length: Approx. 45mm / 1.77inLine Length: Approx. 1.4meter / 4.6ft.Package List:4 x Proximity Switch8 x Gasket Fixing Accessories8 x Hex Thread Fixing AccessoriesNote:Do not stay in liquid environment for a long time.
