Panasonic CX 441 Photoelectric Sensor, Range: 2mm~50mm, NPN Output, IP67

The CX 441 features an NPN open-collector (sinking) output. Connect the brown wire to your positive supply voltage (12-24V DC), the blue wire to ground (0V), and the black wire is the output signal. The black wire will switch to ground (sink current) when an object is detected. Always connect a pull-up resistor to a positive voltage on the black wire if your controller requires a voltage signal.

Yes, the detection range from 2mm to 50mm is typically adjustable. The sensor housing includes a sensitivity adjustment potentiometer. Refer to the official Panasonic datasheet for detailed instructions on setting the detection threshold to avoid false triggers and ensure reliable operation for your specific target material and color.

With its IP67 rating, the CX 441 is protected against dust ingress and can withstand temporary immersion in water up to 1 meter for 30 minutes. It is suitable for damp, dusty, or oily industrial environments. However, for continuous outdoor exposure to direct rain or UV, additional protective enclosures or a sensor with a higher IP rating (e.g., IP69K) should be considered.
