EE-SB5(-B)
Be sure to read Precautions on page 24.
■ Dimensions
■ Features
Note: All units are in millimeters unless otherwise indicated.
• 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).
• Model with PCB terminals (EE-SB5-B).
• Recommended sensing distance = 5.0 mm
