OGH200 Diffuse Reflection Sensor 250mm PNP M12 | IFM

The Original New IFM OGH200 Diffuse Reflection Sensor with Background Suppression is a robust photoelectric sensor designed for reliable object detection in harsh industrial environments. Featuring precise geometric background suppression, this sensor reliably detects objects regardless of colour while ignoring background interference. The M18 threaded stainless steel housing, intuitive potentiometer adjustment, and red light sensing make it ideal for factory automation, material handling, and machine control applications.

Core Engineering Highlights:
15–250mm detection range | PNP light‑on output | Red light (624nm) | 10–36V DC operating voltage | 200mA output current | 1kHz switching frequency | M18 x 1 threaded stainless steel housing | IP65 protection | –25°C to +60°C operating temperature | M12 connector
