Dimensions
Note: All units are in millimeters unless otherwise indicated.
Features
Dust-tight construction model with a 5 mm sensing distance.
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.
