OPB708传感器变送器的光学传感器-反射式-模拟输出规格书PDF中文资料

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
