R305 Retroreflective Area Sensor with IO-Link
Reliable Object Detection— Regardless of Shape or Size
R305 Retroreflective Area Sensor with IO-Link
The continuous availability of diagnostic data also underpins predictive maintenance strategies.
Easy Commissioning and Stable Operation
The Easy Alignment Mode enables fast installation using a visual LED indicator. A side-looker adapter allows 90-degree offset mounting for confined installation spaces.
Pepperl + Fuchs introduces the R305 retroreflective area sensor, designed to reliably detect irregularly shaped objects from a height of just 2 mm. With a 60 mm light band, configurable detection parameters, and a sensing range of up to 4 m, the sensor offers exceptional flexibility for logistics and materialhandling applications. Integrated height measurement and an IO- Link interface offer significant advantages over conventional retroreflective sensors.
Reliable Detection of Small and Nonhomogeneous Objects
In many applications, precise object detection is essential for smooth operation. Traditional retroreflective sensors often reach their limits when detecting very small objects that are not perfectly aligned within a point-shaped detection beam. Irregular contours may also cause multiple switching signals.
The R305 retroreflective area sensor overcomes these limitations by using a wide light band rather than a single-point beam. Even very narrow object edges are detected reliably, and interrupted contours trigger only a single switching event.
Maximum Flexibility for a Wide Range of Applications

The sensor’ s light band consists of five individual beams, each 12 mm wide. Individual beams can be deactivated to ignore interfering objects or to adjust the detection height to accommodate narrow openings. The contrast level can also be adjusted to reliably detect transparent materials such as clear glass.
Users can select between two operating modes:
• Standard resolution mode: detection range up to 4 m
• High resolution mode: minimum detectable object down to 2 mm
Adjustments can be made directly on the device via rotary selector switch and push button, or precisely configured using IO-Link.
IO-Link for Optimised Processes and Predictive Maintenance
In addition to detecting object presence, the R305 simultaneously measures object height. Measurement and status data are transmitted to the control system via IO-Link, enabling sorting, classification, and monitoring applications that improve process quality and efficiency.
The Auto-Teach function automatically adapts the sensor to its environment after power-up, eliminating the need for manual readjustment after maintenance shutdowns. During operation, intelligent signal compensation automatically adjusts light intensity to counteract dust, dirt, or changing ambient light conditions, ensuring consistently reliable detection and reduced maintenance effort.
