VCNT2020 www.vishay.com Vishay Semiconductors Reflective Optical Sensor With Transistor Output FEATURES * Package type: SMD * Detector type: phototransistor * Dimensions (L x W x H in mm): 2.5 x 2 x 0.8 * Operating range within > 20 % relative collector current: 0.2 mm to 2.5 mm * Emitter wavelength: 940 nm * Moisture sensitivity level (MSL): 4 * Material categorization: for definitions of compliance please see www.vishay.com/doc?99912 DESCRIPTION The VCNT2020 is a reflective sensor in a miniature SMD package. It has a compact construction where the emitting light source and the detector are arranged in the same plane. The operating infrared wavelength is 940 nm. The detector consists of a silicon phototransistor. The sensor analog output signal (photo current) is triggered by detection of reflected infrared light from a close by object. The sensor has a built in daylight blocking filter, which greatly suppresses disturbing ambient light and therefore increases signal to noise ratio. APPLICATIONS * Position sensor * Optical switch * Optical encoder (e.g. disc and tape drives for DVD and / or camera applications) * Object detection (e.g. paper presence in printer and copy machines) PRODUCT SUMMARY PART NUMBER DISTANCE FOR MAXIMUM CTRrel (1) (mm) DISTANCE RANGE FOR RELATIVE Iout > 20 % (mm) TYPICAL OUTPUT CURRENT UNDER TEST (2) (mA) DAYLIGHT BLOCKING FILTER INTEGRATED 0.5 0.2 to 2.5 1.6 Yes VCNT2020 Notes (1) CTR: current transfer ratio, I /I out in (2) Conditions like in table basic characteristics/sensors ORDERING INFORMATION ORDERING CODE PACKAGING VOLUME (1) REMARKS VCNT2020 Tape and reel MOQ: 3000 pcs Drypack, MSL 4 Note MOQ: minimum order quantity (1) ABSOLUTE MAXIMUM RATINGS (Tamb = 25 C, unless otherwise specified) PARAMETER TEST CONDITION SYMBOL VALUE UNIT INPUT (EMITTER) Reverse voltage VR 5 V Forward current IF 100 mA IFSM 500 mA V(BR)CEO 20 V VECO 7 V IC 20 mA Forward surge current tp 100 s OUTPUT (DETECTOR) Collector emitter breakdown voltage Emitter collector voltage Collector current SENSOR Tamb 25 C Ptot 170 mW Ambient temperature range Tamb -25 to +85 C Storage temperature range Tstg -25 to +85 C Tsd 260 C Total power dissipation Soldering temperature In accordance with Fig. 11 Document Number: 84285 1 For technical questions, contact: sensorstechsupport@vishay.com THIS DOCUMENT IS SUBJECT TO CHANGE WITHOUT NOTICE.
