1、With red LED work indicator, intuitive and convenient, simple to operate 2、The power cable length is 1.5 meters, thicker cable and more stable transmission 3、Diffuse reflection detection method, sensitive response, detect objects more agilely 4、Adopt DC 4‑wire normally open NPN NO output form, which has stable performance 5、Suitable for ecurity equipment, textile equipment, CNC machine tools, security inspection equipment, automated production lines, electronic machinery, etc. Item Type: Photoelectric Switch Proximity Sensor : BERM Model: CDD-40N Output Form: DC 4-wire normally open NPN NO Working Voltage: DC12-24V 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 object Size: 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. 1 x Photoelectric Switch Proximity Sensor Note: 1.Please allow 1-3 mm error due to manual measurement and 1-3g weight error make sure you don't mind before ordering. 2.Due to the lighting of the photos and the difference of monitors, the pictures may not reflect the actual color of the real item.
