Feature: 1. High Accuracy: Built in anti interference intelligent sensing chip enables quick frequency response as well as high accuracy. 2. Clear Indicator: When a metal object is sensed, the light is on as normally open, and the light is off as normally closed. 3. Easy to Adjust: The sensing distance is 10mm, which can be conveniently adjusted according to your various detection needs. 4. Broad Utility: Allows for extensive application in assembly lines, machine tools, automation equipment and so on, very useful. 5. Reliable Uses: Combining ABS probe and nickel plated brass material, the proximity switch has great durability for long use. Specification: Item Type: Proximity Switch Product Material: ABS + Brass Product Model: NJK-5003D Power Supply Voltage: DC 5-30V Rated Current: 300MA Output Mode: NPN NC Sensing Distance: Approx. 10mm / 0.39in Product Length: Approx. 1.2meter / 3.94ft Nut Size: M18 Product Quantity: 10pcs Product Size (cable length not included): D18 x 43mm / 0.71 x 1.69in Application Scope: For assembly lines, machine tools, automation equipment, etc. . Package List: 10 x Proximity Switch20 x Clamp Nut20 x Washer10 x Magnetic Sheet Note: The current sensor must appropriately select products of different specifications according to the rated effective value of the measured current. If the measured current exceeds the limit for a long time, it will damage the end pole power amplifier tube (referring to the magnetic compensation type). Generally, the duration of 2 times the overload current should not exceed 1 minute.
