OS5501

The OS5501actuator-type photosensor combines an infrared ligh-emitting diode and high-sensitivity phototransistor into a single unit with an actuator.The typical applications of OS5501 include detection of paper movement and amount of remaining paper in copiers,printers,facsimile machines,printing equipement and other office automation products,detection of the passage of paper currency and coins,detection of the passage of wafers and frame-type parts,detection of cassette tape and video tape insertion and the rotation position detection of low-speed rotating bodies.

Here you can get some information about the features of OS5501.First,unitized construction of sensor and moving portion ensures excellent detection effectiveness.Secondly,unitized construction simplifies design work and lowers cost.Besides,compact design enhances the compactness of your equipment and is usable in cramped quarters.Furthermore,extremely simple construction enables quick,easy mounting.Fifthly,small actuator operating torque makes these sensors ideal for detection such light objects as moving paper or wafers.At last,actuator section configuration may be changed to suit special requirments.

What comes next is about the maximum ratings of OS5501(T_a=25).First is for light-emitting side.The I_F (forward current) is 50 mA.The V_R (reverse voltage) is 5 V.Then is for light-receiving side.The V_CEO (collector-emitter voltage) is 30 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 75 mW.The T_opr (operating temperature) is from -25 to +80.The T_stg (storage temperature) is from -30 to +95.

The following is about electrical characteristics of OS5501 (T_a=25).First is for light-emitting side.The typical V_F (forward voltage) is 1.15 V and the maximum is 1.30 V at I_F=10 mA.The maximum I_R (reverse current) is 10A at V_R=5 V.Then is for light-receiving side.The typical I_D (dark current) is 5 nA and the maximum is 100 nA at V_CE=24 V,I_F=0.Next is about the transmitting characteristics.The minimum I_C (collector current) is 2.0 mA and the typical is 2.0 mA at I_F=20 mA,V_CE=5 V.The typical V_CE(sat) (collector-emitter saturation voltage) is 0.1 V and the maximum is 0.4 V at I_F=20 mA,I_C=0.25 mA.
