Description:

Each reflectve object sensor in the OPB708, OPB709, OPB740 through OPB746 and OPB740WZ through OPB746WZ series consists of an infrared emitng diode and a NPN silicon phototransistor or a photodarlington. The OPB747WZ and OPB748WZ consist of a Red visible LED and a low light level rejecton (RBE) NPN silicon phototransistor. The Red LED allows beter contrast rato when detectng Black marks on a White surface. All these devices are mounted side-by-side on converging optcal axes in a black plastc housing focusing on a small area and depth of feld.

Features:

• Focused for maximum sensitvity

• Phototransistor or photodarlington output

• Crosstalk does not exceed specifed ICEO

• 24” (610 mm) wire length

• 26 AWG wire size

Applications:

• Non-contact reflectve object sensor

• Assembly line automaton

• Machine automaton

• Machine safety

• End of travel sensor

• Door sensor

• Thermal Paper Mark

OPB742WZ属于传感器，变送器 > 光学传感器 - 反射式 - 模拟输出。梯梯电子集成制造服务(苏州)有限公司制造生产的OPB742WZ光学传感器 - 反射式 - 模拟输出模拟输出反射式光学传感器产品族中的产品包含彼此相邻并朝向相同方向安装的光发射器和光敏元件（通常是光电晶体管），以便确保发射器发出的光在传感器视场中被物体反射时可以被设备内的传感元件检测到。这种类型的模拟输出传感器以最少的处理量直接传送由光电传感器产生的信号，同时用户需要提供自己的解释机制来确定物体检测结果。
