Features Convenient to Operate: With red LED work indicator, intuitive and convenient, photoelectric switch is simple to operate. Stable Transmission: The photoelectric switch power cable length is 1.5 meters, thicker cable and more stable transmission. Sensitive Response: Diffuse reflection detection method, the photoelectric switch is sensitive response, detect objects more agilely. Reliable Performance: Adopt DC 4-wire normally open NPN NO output form, the photoelectric switch has stable performance. Scope of Application: Suitable for ecurity equipment, textile equipment, the photoelectric switch is CNC machine tools, security inspection equipment, automated production lines, electronic machinery, etc. Specification: Item Type: Photoelectric Switch Proximity Sensor Model: CDD-40N Output Form: DC 4-wire normally open NPN NO Working Voltage: DC10-30V Output Current: 200mA Metal Probe Diameter: φ18MM Detection Distance: 10-30MM ±10% Detection Mode: Diffuse reflection Structure Type: Built-in amplifier Cable Length: 1.5 meters Detection Object: Opaque objectSize: Approx. 18 x 64 x 28mm / 0.7 x 2.5 x 1.1in Principle: 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 mode Applications: Security equipment, textile equipment, CNC machine tools, security inspection equipment, automated production lines, electronic machinery, etc. Package List: 1 x Photoelectric Switch Proximity Sensor Note: Please allow error due to manual measurement.
