| GP2U06 General Description Sharp's GP2U06 is dust sensor which integrated optical sensor portion and signal amplifier portion. It is suitable for indoor air purifier sensor because of compact, thin, low dissipation current type. High Sensitivity Dust Sensor Outline Dimensions Detecting window 3.2 38 1 2 3 4 Compact and Thin Type Dust Sensor for Detecting Particles (Unit : mm) 9 58 Connector Features (1) Compact, thin type (58 x 38 x 25mm) (2) High sensitivity (Dust detecting sensitivity : TYP.0.5V/(0.1mg/m3) (3) Can detect dust even in low density area (Minimum particle density : TYP. 0.02mg/m3) (4) Operating voltage : 5V (5) Low dissipation current (Icc : MAX. 15mA) 25 Terminal configuration 1 2 3 4 GND Output terminal Emitting device operating terminal Vcc Applications (1) Air purifiers (2) Air conditioners Absolute Maximum Ratings Parameter Supply voltage Input terminal voltage Operating temperature Storage temperature Symbol Vcc VLED Topr Tstg Ratings -0.3 to +7 -0.3 to +Vcc -10 to +65 -20 to +80 Unit V V C C (Ta=25C) Remarks Open drain input - Operating supply voltage Symbol Vcc Ratings 50.5 Unit V Remarks - (Notice) * In the absence of device specification sheets, SHARP takes no responsibility for any defects that may occur in equipment using any SHARP device shown in catalogs, data books, etc. Contact SHARP in order to obtain the latest device specification sheets before using any SHARP device. * Specifications are subject to change without notice for improvement.
