- Adjustable Sensitivity: Built-in sensitivity adjustment dial allows precise calibration according to material properties and object dimensions (adjustment range: 3-8mm)
- Environmental Resistance: IP67-rated housing ensures reliable operation in temperatures ranging from -25℃ to +70℃, with excellent resistance to oil, dust, and humidity
- Electrical Performance: Supports 10-30V DC wide voltage input, offers both NPN/PNP output configurations (NO normally open type) with 200mA maximum load capacity
- Installation Flexibility: Compact cylindrical design (Φ18mm) with standard M18 threaded mounting, compatible with flush or non-flush installation
Technical Specifications:
Detection Range: 8mm (metal)/3-5mm (non-metal, material-dependent)
Response Frequency: 50Hz
Circuit Protection: Reverse polarity and short-circuit protection
Material: Stainless steel sensing surface with PBT engineering plastic housing
Typical Applications:
Ideal for position detection in packaging machinery, container identification in food production lines, wood panel positioning in furniture manufacturing, and liquid level monitoring in chemical processing.
