Description
PEPPERL+FUCHS MLV12-8-H-250-RT4765b124 Diffuse Reflection Photoelectric Sensor
Product Dimensions:
The Pepperl+Fuchs MLV12-8-H-250-RT/47/65b/124 is a high-performance diffuse mode sensor with background suppression. It uses triangulation technology to ensure that objects are detected accurately regardless of their color or texture, while effectively ignoring any background beyond the set detection range.

## Product Advantages
-
Color Independence: Reliable detection of all surfaces (dark, light, or structured) with minimal black-white difference ($10\%$ at 250 mm).
-
Background Suppression: Uses triangulation to precision-cut detection at a specific distance, preventing false triggers from background objects.
-
High Visibility Indicators: Equipped with ultra-bright LEDs for Power-ON (green) and Switching State (yellow). The green LED flashes in case of a short circuit.
-
Interference Resistance: Not sensitive to ambient light (including energy-saving lamps) and designed for multiple device installations without cross-talk.
-
Rugged Construction: Features a robust metal-reinforced housing and an M12 connector that can rotate 90° for flexible mounting in tight spaces.
## Important Notes & Precautions
-
Adjustment: The detection range is electrically adjustable via a potentiometer. Ensure the “cut-off” point is set slightly beyond the target but before the background.
-
Cleaning: The optical face is made of plastic. Use a soft, damp cloth for cleaning; avoid harsh chemicals or abrasive materials that could scratch the lens.
-
Wiring: Always ensure the power is off before connecting the M12 plug. The outputs are short-circuit and reverse-polarity protected, but proper wiring is essential for long-term stability.
-
Environment: While IP67 rated, avoid constant high-pressure water jets directly on the lens to maintain optimal optical clarity.
## Product Applications
-
Packaging Industry: Detecting boxes or containers on a conveyor belt while ignoring the metal rails or the belt itself.
-
Automotive Assembly: Identifying parts with varying reflectivity (shiny metal vs. matte plastic).
-
Material Handling: Detecting the presence of small objects in bins where the bin bottom must be suppressed.
-
Print & Paper: Detecting dark paper or cardboard against light-colored machine parts.
