IFM O6H300, PE Diffuse Reflection Sensor, BGS, IP69K, 2-200m

Manufacturer / Series

ifm electronic — O6 series (photoelectric sensors)

Model

O6H300

Sensor Type

Photoelectric (PE) diffuse reflection sensor (emitter + receiver in one housing; uses light reflected from the target)

Detection Method

BGS (Background Suppression) / triangulation: measures angle/position of returned light so it can detect a target at a set distance while ignoring objects behind it

Sensing Range

2–200 mm (short-range, precision distance window). If you meant “2–200 m”, that would normally be a through-beam or retro-reflective long-range model, not a BGS diffuse type.

Best Use

Detecting objects reliably regardless of background (e.g., parts on a conveyor with a fixed backplate, picking edge/shape changes, presence detection near a machine)

What it Detects Well

Most solid objects (metal, plastic, cardboard, matte surfaces). With BGS it’s more stable when the background is close or reflective

Limitations

Very dark, highly absorbing, transparent, or mirror-like targets can reduce stability; angled shiny targets may need alignment or sensitivity tuning

Output (Typical for this class)

Usually 1x switching output (PNP/NPN depending on variant). Many ifm O6 models are PNP NO/NC selectable—confirm from the exact datasheet suffix if present

Adjustment

Typically via teach button or potentiometer (model-dependent). BGS often supports “teach distance” so the sensor locks onto a target distance

Response / Switching

Designed for fast industrial detection (exact response time depends on variant; typically in millisecond range)

Housing / Protection

IP69K: high-pressure, high-temperature washdown resistant (food, beverage, washdown environments)

Typical Mounting

Standard M18-style or rectangular housing depending on O6H design; aligned toward target at a stable distance within 2–200 mm

Recommended Setup Tips

Keep target within the 2–200 mm window, teach at the real working distance, avoid direct reflections into the lens, and test with your darkest/most reflective product to confirm margin
