OS-2202

OS-2202 is a reflection-type photosensor which makes use of an infrared LED and high-sensitivity phototransistor.Here you can get some information about the features.First,it saves space because only a single unit is needed.Then is simple structure which is suitable for a wide range of applications.The last one is designed for immunity to stray ambient light.The typical applications of OS-2202 include coin,metal and paper detection,paper and film detection,start/end detection for cassette and VTR tape equipment,rpm detection for rotating machinery such as copies and printers and the detection of remainning fluid and edge position.

What comes next is about the maximum ratings of OS-2202 (T_a=25).First is for light-emitting side.The I_F (forward current) is 100 mA.The V_R (reverse voltage) is 5 V.Then is for light-receiving side.The V_CEO (collector-emitter voltage) is 40 V.The V_ECO (emitter-collector voltage) is 5 V.The I_C (collector current) is 50 mA.The P_C (collector power dissipation) is 150 mW.The T_opr (operating temperature) is from -25 to +85.The T_stg (storage temperature) is from -30 to +100.

The following is electrical characteristics of OS-2202 (T_a=25).First is for light-emitting side.The typical V_F (forward voltage) is 1.3 V and the maximum is 1.4 V at I_F=50 mA.The maximum I_R (reverse current) is 10A at V_R=5 V.Then is for light-receiving side.The maximum I_CEO (I_D) (dark current) is 200 nA at V_CE=30 V.Next is about the transmitting characteristics.The maximum V_CE(sat) (collector-emitter saturation voltage) is 0.4 V at I_F=50 mA,I_C=1 mA.The typical t_r (rise time) is 3s and the typical t_f (fall time) is 4s at V_CC=5 V,I_C=1 mA,R_L=100.
