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.
External synchronization input
function [BF4R(G)-E]
By using external synchronization function, the time
for making sensing can be specified by external
synchronization. Trigger synchronization and gate
synchronization are available.

Stop transmission function
[BF4R(G)-E]-Operation test
● Below test is available under Light ON state only.
● If input of stop transmission is at Low state, transmission
light will be stopped.
● It can check normal or abnormal state of the sensor
without moving the target.

(Note1) If transmission is stopped control output must
turn on, but if control output does not turn on,
it seems that sensor has some problems.
