IFM OGH200 Diffuse Reflection Sensor – OGH-HPKG/US100

The IFM OGH200 is a precision diffuse reflection sensor with adjustable background suppression, ideal for reliable object detection in industrial environments. Using a focused 624 nm red light beam, it detects objects up to 250 mm away while ignoring backgrounds, delivering stable switching even with dark or low-reflectivity materials. The M18 threaded stainless steel housing, PNP output, and IP65 rating make the OGH200 a dependable choice for factory automation, materials handling, and packaging applications.
