DescriptionThe OPB125A consists of an infrared emitting diode and an NPN silicon photodarlington mounted side-by-side on converging optical axes, in a black plastic housing. The photodarlingtan responds to radiation from the LED only when a reflective object passes within its field of view.
Features of the OPB253A are: (1)photodarlingtan output; (2)low profile to facilitate stacking; (3)low cast plastic housing; (4)4.0 inches (101.6 mm)minimum length lead wire.In no event shall Sensitron Semiconductor be liable for any damages that may result from an accident or any other cause during operation of the user's units according to the datasheet(s). Sensitron Semiconductor assumes no responsibility for any intellectual property claims or any other problems that may result from applications of information, products or circuits described in the datasheets.
The absolute maximum ratings of the OPB253A can be summarized as:(1)collector-emitter voltage:25 V;(2)storage temperature range:-40 to 125;(3)forward DC current:60mA;(4)power dissipation:50mW;(5)operating temperature:-40 to 100.The products described in this document are designed, developed and manufactured as contemplated for general use, including without limitation, ordinary industrial use, general office use, personal use, and household use, but are not designed, developed and manufactured as contemplated (1) for any use that includes fatal risks or dangers that, unless extremely high safety is secured, could have a serious effect to the public, and could lead directly to death, personal injury, severe physical damage or other loss (i.e., nuclear reaction control in nuclear facility, aircraft flight control, air traffic control, mass transport control, medical life support system, missile launch control in weapon system), or (2) for any use where chance of failure is intolerable (i.e., submersible repeater and artificial satellite).
At present there is not too much information about this model.If you are willing to find more about OPB253A, please pay attention to our web! We will promptly update the relevant information.
