Photoelectric flatpack sensors

Miniature Sensors for the Harshest Environments

Balluff’s newest addition to the photoelectric family, the R01E, complements the proven inductive R01 family of sensors. These sensors offer diffuse versions with ranges up to 100 mm, polarized retroreflective mode with ranges up to one meter, and through-beam sensor with ranges up to 2.2 meters. With a precise, uniform visible red light beam, alignment is easy and objects are reliably detected.

Not only does the small size provide flexibility in installation, but the stainless steel housing is built to survive the toughest applications in the harshest environments. Connections are made by cable or M8 three-pin quick disconnect. Built to Balluff’s highest standards, all R01E sensors offer reverse polarity and short circuit protection. Balluff’s attention to quality, superior sensor design, and performance standards means better reliability, less down time, and higher productivity.

Applications: packaging machinery, assembly machinery, material handling, small part detection, error proofing, general purpose automation.
