V CC = 5 V, RL = ∞ Peak current consumption 200 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 kΩ (see note 2) Response delay time (high to low) 1.5 ms max. The time required for the output to become “Lo” after placing sensing object. Response delay time (low to high) 1.5 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 0.9 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. 134 Single Beam Sensor (1 Beam: 100 mm) EY3A-110-A ■ Characteristics (Paper Table Glass: t = 6 mm max., Transparency Rate: 90% min.) (Ta =0° C to 60° C) Item Characteristic value Sensing density Lusterless paper with an OD of 0.42 max. (sensing distance: 50 mm) (see note) Non-sensing distance 150 mm (from the top of the sensor), OD: 0.05 Paper sensing distance 100 mm (from the top of the sensor) Ambient illumination Sunlight: 3,000 lx max., fluorescent light: 2,000 lx max. Note: 1. The data shown are initial data. 2. Optical darkness (OD) is defined by the following formula: OD = − log10 PIN (mW): POUT PIN Light power incident upon the document POUT (mW): Reflected light power from the document ■ Optical Path Arrangement 150 (see note 2) 14 100 (standard value) 10 dia. (see note 1) 8.9 Paper supporting plate Glass Note: 1. The part with oblique lines indicates the paper sensing area of the EY3A-110-A, which is practically determined by the diameter of the beam and its tolerance. 2. The non-sensing distance of the EY3A-110-A is determined using a paper with an OD of 0.05. ■ Engineering Data EY3A-110-A Distance Characteristics (Typical) 1.4 4.75 V 5.0 V 5.25 V 1.2 OD (value) 1 0.8 0.6 0.4 0.2 80 85 90 95 100 105 110 115 120 125 130 Distance (mm) Single Beam Sensor (1 Beam: 100 mm) EY3A-110-A 135
