Procurement Notes

Verify the specific ordering code against official SICK documentation to ensure correct output type and housing configuration. Confirm that the required sensing distance falls within the 4 mm to 180 mm operational window for your specific installation geometry. Ensure power supply compatibility with the 10 V to 30 V DC specification before procurement.

Selection Notes

Select this model when optical proximity detection is preferred over inductive or capacitive methods due to its ability to detect various material types. Consider the NPN output requirement for compatibility with existing control systems. Evaluate the mechanical mounting constraints against the sensor's physical dimensions to ensure proper alignment within the target application environment.
