OS3701

OS3701 is a kind of high-performance interruptor-type photosensor that uses GaAs infrared light-emitting diodes and opto-electronic intergrated receiving circuits with amplifier and Schmitt trigger circuit intergrated onto a single chip.It has srew mountings and deliver an open-collector output.The typical applications of OS3701 include timing position detection for rotating machinery such as copiers and printers,photoelectric switches,counters and encoders and an actuator or other device can be added for moving detection of paper,water and other light weight objects.

Here you can get some information about the features of OS3701.First,by unitizing the light-receiving element and surrounding signal processing circuitry,both a reduction in parts count and desigh simplicity have been achieved.The second is open-collector output.Then is interchangeable connectors.The last one is mounted by a single screw.

What comes next is about the maximum ratings of OS3701 (T_a=25).The V_CC (supply voltage) is 10 V.The V_OUT (output voltage) is 28 V between collector-emitter.The I_OUT (output current) is 50 mA which is also transistor collector current.The P_OUT (output power dissipation) is 150 mW which is also transistor collector dissipation.The T_opr (operating temperature range) is from -20 to +85.The T_stg (storage temperature range) is from -30 to +100.

The following is about electrical characteristics of OS3701 (T_a=25,V_CC=5 V±10%).When the photo path is open,the maximum I_CC (current consumption) is 30 mA and the typical is 20 mA,the maximum V_OUT(Sat) (ON voltage) is 0.35 V at I_OUT=16 mA.When the photo path is blocked,the maximum I_CC (current consumption) is 30 mA and the typical is 20 mA,the minimum V_OUT (OFF voltage) is V_CC*0.9 V at R_L=47 k.The response frequency is 3000 Hz at R_L=47 k.The output is open collector.
