RLG28 Retroreflective Area Sensors
RLG28 Retroreflective Area Sensor
RLG28 series retroreflective area sensors are used to detect objects, especially their leading edges, regardless of position, shape, or texture. They offer a simple, fast, affordable, and consistent way to sense compared to a thru-beam light grid or multiple single-beam sensors. Retroreflective area sensors contain multiple transmitter and receiver elements in one housing aimed at a reflector, resulting in a continuous height or width detection field over the entire distance from the sensor to the reflector.
Typical applications
- Leading edge detection of all types of pallets
- Identification of pallet protrusions (overhang control)
- Detection of objects with irregular or undefined edges (stacks of newspaper)
- Presence confirmation of objects with variable positions (such as board bouncing on moving conveyor or bent rods)
- Sensing objects with changing shapes or heights (pouches or bags)
- Verification of object presence regardless of texture (reflective chrome, glossy foil wrap, soiled or damaged trays)
- Detection of falling objects (ejection control)
- Muting function for use with safety light curtains
RLG28 features include:
- More detection coverage than single-beam sensors
- More cost-effective than an array of single-beam sensors or thru-beam light grids
- Reliable detection regardless of shape, position, or texture
- Constant resolution over entire detection area
- Low temperature operation down to -30 degrees C (-22 degrees F)
- Pepperl+Fuchs’ exclusive 4-in-1™ output technology to reduce inventory costs
- Built-in cross-talk protection
- Mounts and wires same as single-beam sensors
- Highly visible transmitter LEDs for alignment ease
- Bright, enhanced function LEDs indicate sensor status
