Pepperl+Fuchs 3RG6012-3AC00-PF 559661 Ultrasonic Sensors 60-300mm Diffuse Sensing Range

1. Overview of the Pepperl+Fuchs 3RG6012-3AC00-PF 559661

The Pepperl+Fuchs 3RG6012-3AC00-PF 559661 belongs to the Pepperl+Fuchs cylindrical M30 ultrasonic sensor family. It utilizes a diffuse sensing range of 60–300 mm to reliably identify transparent, dark, or porous objects without contact. Its robust nickel-plated brass housing (Ø30 × 85 mm) and IP67 protection rating ensure stable operation in harsh environments such as moisture, dust, and oil, making it a versatile "non-contact measurement expert" for the packaging, logistics, food, and automotive industries.

2. Features
Intelligent Teach: Using a teach-in button or an external teach cable, you can freely set a two-point switch window within a range of 60–300 mm, enabling switching between single-point and window modes.
Temperature Compensation: A built-in temperature sensor corrects for sound velocity drift in real time, ensuring a stable accuracy of ±1 mm across the entire temperature range.
Status Indicator: A dual-color green/yellow LED indicates "target present" and "teach successful" with a single click, making fault diagnosis intuitive.
Anti-interference: The ultrasonic 400 kHz carrier combined with digital filtering effectively suppresses reflections from adjacent metal, ambient noise, and fog.
Flexible Installation: An M30 × 1.5 thread and a 90° rotatable connector support top, side, or flush mounting, allowing for orientation adjustment without the need for additional brackets.
3. Typical Applications
• Packaging Machinery: Counting and positioning transparent films and glass bottles to prevent false photoelectric detection. • Logistics and transportation: Carton and pallet in-place detection, replacing mechanical limit switches with zero wear and a long service life.
• Food and beverage: Liquid level and body detection on high-speed PET bottle and can filling lines, meeting IP67 hygienic washdown requirements.
• Automotive manufacturing: Vehicle body contour or bumper presence detection, adaptable to dark, reflective, and curved surfaces.
