WTB26 为带背景抑制功能的漫反射光电传感器。根据待检物体及其可能有的位于后
面的背景的反射比,在已设置触发感应距离 (x) 与背景之间保持最小距离 (y)。
检查使用条件:使用随附的图表 [参见插图 5 和 7] 调整触发感应距离和与物体或背
景的距离及物体的反射能力(x = 触发感应距离,y = 已设置的触发感应距离和背景
(白色,90%)之间的最小距离,反射比:6% = 黑色 1,18% = 灰色 2,90% =
白色 3(DIN 5033 规定的标准白))。我们建议您使用低反射比的物体进行设
置。
背景抑制功能的最小距离 (= y) 可以从图表
示例:x = 600 mm,y = 40 mm。即,当距设置的触发感应距离 > 40 mm 时,才
能抑制背景(白色,90%)。
