< Application >

● To extend sensing distance by the diffuse reective type:

If ber optic sensor is used in place where there are targets with high reectivity and low reectivity, it is able to get stable detection by adjusting max. sensitivity.

● When it is used as transmitted beam type at bad

environment : If ber optic sensor is used in place where there is lots of dust or moisture, it might cause malfunction. Please max. sensitivity then it can perform stable detection.

Answer Back function[BF4R(G)-R]

When ON or OFF input of remote sensitivity setting is applied, after 300ms, self-diagnosis output turns on for 40ms and then the sensor keeps normal sensing state. (Note: Time chart)

※

Self-diagnosis output does not turn on if there is no difference of sensitivity between ON input and OFF input and stable sensing is not executed, but stable sensing operates after 340ms.

OFF Delay timer function

(BF4R/BF4RP/BF4R-R/BF4G/BF4GP/BF4G-R)

Standard type and Remote sensitivity setting type both contain a built-in approx. 40ms fixed OFF Delay timer. The timer works when the timer selection switch is set to 'OFD'. The output is turned off after remaining on for additional 40ms at OFF position of the sensing output. It is useful when the response time of the connected device is slow or when the sensing signal from a tiny object is too short.
