EY3A-3051
■ Dimensions
Note: All units are in millimeters unless otherwise indicated.
■ Features
? Simultaneously senses three objects positioned differently, thus
saving space.
Positioning boss
Center of detector
? Ensures higher sensitivity and external light interference resistivity
than any other photomicrosensor.
? Narrow sensing range ensures stable sensing of a variety of sens-
ing objects.
■ Application Examples
Sensing of paper sizes.

The time required for the output to become “Lo ” after placing sensing
object.
The time required for the output to become “Hi” after removing sensing
object.
Note: 1. These conditions are for the sensing of lusterless paper with an OD of 0.8 maximum located at the correct sensing position of the Sensor
as shown in the optical path arrangement on the next page.
2. These conditions are for the sensing of the paper supporting plate with an OD of 0.05 located using the glass plate without paper as
shown in the optical path arrangement on the next page.
