Pepperl+Fuchs offers its ML6 Series subminiature photoelectric sensors with dual sensor redundant detection and independent outputs. These subminiature photoelectric sensors are also available in long-range background suppression sensing models, and retroreflective models with no sensing deadband.
These sensors provide dual beams from two emitter LEDs that reflect light to two receivers, while two independent outputs indicate the state of each separate beam. Because it acts like two sensors in one housing, translucent paper, plastic, and fabric webs can be aligned or guided economically. When the web is properly positioned, one beam detects the web while the other beam does not. Using this sensor, the gap between two objects can be detected while suppressing the detection of small particles such as textile fibers. Other potential applications include semiconductor and PCB positioning for conveying and buffering.
The two long-range background suppression sensing models can be mounted farther away from the object to be detected. These subminiature photoelectric sensors are ideal for applications in the material handling, printing, semiconductor, and solar industries.
Two ML6 series retroreflective sensing models with no sensing deadbandare used with a corner-cube reflector and are polarized so that shiny objects will not be mistaken for the reflector. An innovative single optical axis design eliminates deadband. This is helpful in applications that require more signal strength than is available with background suppression sensors, and that have either very close or long sensing distances.
All non-thru-beam subminiature photoelectric sensors feature integrated cross-talk immunity to make side-by-side mounting possible, a tamperproof design, 4-in-1 output to reduce inventory and wiring, and immunity to ambient light even for high frequency energy-saving lights.
