Feature:1. With red LED work indicator, intuitive and convenient, simple to operate2. The power cable length is 1.5 meters, thicker cable and more stable transmission3. Diffuse reflection detection method, sensitive response, detect objects more agilely4. Adopt DC 4wire normally open NPN NO output form, which has stable performance5. Suitable for ecurity equipment, textile equipment, CNC machine tools, security inspection equipment, automated production lines, electronic machinery, etc.Specification:Item Type: Photoelectric Switch Proximity SensorBrand: BERMModel: CDD-40NOutput Form: DC 4-wire normally open NPN NOWorking Voltage: DC12-24VOutput Current: 200mAMetal Probe Diameter: 18MMDetection Distance: 10-30MM 10%Detection Mode: Diffuse reflectionStructure Type: Built-in amplifierCable Length: 1.5 metersDetection Object: Opaque objectSize: Approx. 18 x 64 x 28mm / 0.7 x 2.5 x 1.1inPrinciple: The diffuse reflection photoelectric switch is a sensor that integrates the transmitter and the receiver. When a detected object passes, the object reflects a sufficient amount of light emitted by the photoelectric switch to the receiver, so the photoelectric switch is a switch when the surface of the signal-detected object is bright or its reflectance is high, the principle of the diffuse reflection photoelectric switch is the detection modeApplications: Security equipment, textile equipment, CNC machine tools, security inspection equipment, automated production lines, electronic machinery, etc..Package List:1 x Photoelectric Switch Proximity SensorNote:Please allow error due to manual measurement.
