Multiple Beam Sensor (3 Beams: 50 mm)

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 “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.
