Photomicrosensor (Reflective)
EE-SB5(-B)
Be sure to read Precautions on page 25.
■ Dimensions
Note: All units are in millimeters unless otherwise indicated.
■ Features
? Dust-tight construction.
? With a visible-light intercepting filter which allows objects to be
sensed without being greatly influenced by the light radiated from
fluorescent lamps.
? Mounted with M3 screws.
? Model with soldering terminals (EE-SB5).
Two, 3.2 ± 0.2 dia. holes
