About detecting characteristics
If reflectance is extremely bad(mourning dress or oil-stained working clothes etc.), it is impossible to measure even
if detection distance is within 1m. Also, it can't detect mirror-surface objects such as stainless polished surface
stably. Detecting precision(Reference value) is +/- 0.1m up to 1m and is +/- 0.1 time against the distance at 1m or
more in case of kent paper with 300
×
300mm. Detecting error with lower reflectance is getting larger. We
recommend to test with a sample.

Setting of detecting area
Setting of output 1 : It is free to set from 0 to 10m for optical axis direction with 7
points pointer.
Setting of output 2 : Linear setting to progressive direction
Fan-shaped setting to optical axis direction
Percentage(%) setting against output 1 pointer
Setting of output 3 : Same as output 2
2-scanning mode(When each detecting area setting, it sets individually for output
1 to 3.)
It judges existing obstacle with continuous 2-scanning
It judges with 1 scanning under normal operating
Mirror reflecting avoidance mode(It sets when each detecting area setting)
It hardly detects the objects with high reflectance 20m away but min. detecting
width at 3m is getting 400mm.
Operating mode
Low-speed scanning mode(Set by software switch)
Scanning time 110ms(100ms when normal operating)
Response delay by mutual interference with PBS with normal operating is made
Within 1 scanning.
Input and each area
Photo-coupler input(Anode common, Each input ON current 4mA)
Setting detecting area changeover
Set area No. by [Input 1], [Input 2], [Input 3] and [Input 4]
Stop emission by getting all [Input 1], [Input 2], [Input 3] and [Input 4] to ON
(OFF : H level input, ON : L level input)
