Single Beam Sensor (1 Beam: 65 mm) EY3A-106-A ■ Dimensions Note: All units are in millimeters unless otherwise indicated. ■ Features • Ensures higher sensitivity and external light interference resistivity than any other photomicrosensor. • Narrow sensing range ensures stable sensing of a variety of sensing objects. ■ Absolute Maximum Ratings (Ta = 25° C) Item Power supply voltage Load voltage Load current Ambient temperature Operating Storage Symbol VCC VOUT IOUT Topr Tstg Rated value 7V 7V 10 mA 0° C to 60° C –15° C to 70° C Note: Make sure there is no icing or condensation when operating the Sensor. ■ Ordering Information Description Single beam sensor Model EY3A-106-A ■ Electrical and Optical Characteristics (Ta = 0° C to 60° C) Item Power supply voltage Current consumption Peak current consumption Low-level output voltage High-level output voltage Response delay time (high to low) Response delay time (low to high) Value 5 V ±5% 50 mA max. 200 mA max. 0.6 V max. 3.5 V min. 1.5 ms max. 1.5 ms max. Condition --VCC = 5 V, RL = ∞ VCC = 5 V, RL = ∞ VCC = 5 V, IOL = 4 mA (see note 1) VCC = 5 V, RL = 4.7 kΩ (see note 2) 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 0.9 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 page the next page. 130 Single Beam Sensor (1 Beam: 65 mm) EY3A-106-A ■ Characteristics (Paper Table Glass: t = 6 mm max., Transparency Rate: 90% min.) (Ta =0° C to 60° C) Item Sensing density Non-sensing distance Paper sensing distance Ambient illumination Characteristic value Lusterless paper with an OD of 0.6 max. (sensing distance: 65 mm) (see note) 100 mm (from the top of the sensor), OD: 0.05 65 mm (from the top of the sensor) 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 POUT PIN PIN (mW):Light power incident upon the document POUT (mW):Reflected light power from the document ■ Optical Path Arrangement 100 (see note 2) 14 8 dia. (see note 1) 65 (standard value) 8.9 Paper supporting plate Glass OD (value) Note: 1. The part with oblique lines indicates the paper sensing area of the EY3A-106-A which is practically determined by the diameter of the beam and its tolerance. 2. The non-sensing distance of the EY3A-106-A is determined using a paper with an OD of 0.05. ■ Engineering Data EY3A-106-A Distance Characteristics (Typical) 1.6 4.75 V 1.4 5.0 V 5.25 V 1.2 1 0.8 0.6 0.4 50 55 60 65 70 75 80 Distance (mm) Single Beam Sensor (1 Beam: 65 mm) EY3A-106-A 131 .
