INSTRUCTION MANUALThank you very much for purchasing Panasonic products. Please read this Instruction Manual carefully and thoroughly forthe correct and optimum use of this product. Kindly keep this manual in a convenient place for quick reference.I/O CIRCUIT DIAGRAMS1Notes: 1)2)The emitter of the thru-beam type sensor does not incorporate theoutput and the control input. When the mating cable is connectedto the pigtailed type, the color of the control input wire is white.Test input (emission halt input) is incorporated only on theemitter of the thru-beam sensor. When the mating cableis connected to the pigtailed type, its color is white.BME-CY11C No.0038-34VCY-11AAC supply㨯Light-ON typeCY-11BAC supply㨯Dark-ON typeCylindricalThru-beam typePhotoelectric SensorCY-21DC supply㨯NPN output typeCY-21-PNDC supply㨯PNP output type٨٨Never use this product as a sensing device for personnel protection.In case of using sensing devices for personnel protection, use products which meet standards, such asOSHA, ANSI or IEC etc., for personnel protection applicable in each region or country.WARNINGSymbols...D1 , D2 : Reverse supply polarity protection diodeZ D1 , ZD2 : Surge absorption zener diodeTr1 : NPN output transistorT r2 : PNP output transistorNote: The output does not incorporate a short-circuit protection circuit.
