Multiple Beam Sensor (3 Beams: 50 mm) EY3A-3051 Dimensions Features Note: All units are in millimeters unless otherwise indicated. * Simultaneously senses three objects positioned differently, thus saving space. * Ensures higher sensitivity and external light interference resistivity than any other photomicrosensor. * Narrow sensing range ensures stable sensing of a variety of sensing objects. Positioning boss Center of detector Application Examples Sensing of paper sizes. 3.2 53325-0510 (Japan Molex) +0.2 0 Absolute Maximum Ratings (Ta = 25 C) dia.

VCC = 5 V, RL = Peak current consumption 300 mA max. VCC = 5 V, RL = --- Low-level output voltage 0.6 V max. VCC = 5 V, IOL = 4 mA (see note 1) High-level output voltage 3.5 V min. VCC = 5 V, RL = 4.7 k (see note 2) Response delay time (high to low) 35 ms max. The time required for the output to become "Lo" after placing sensing object. Response delay time (low to high) 20 ms max. 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. 138 Multiple Beam Sensor (3 Beams: 50 mm) EY3A-3051 Characteristics (Paper Table Glass: t = 6 mm max., Transparency Rate: 90% min.)
