Descripton:

OP550, OP552, OP555, OP750, and OP770 series consists of a NPN silicon phototransistor molded in an epoxy package with a wide receiving angle that provides relatvely even recepton over a large area. The OP750 and OP770 have additonal circuitry to enhance the operaton of the device for stray light levels.

Features:

• Wide receiving angle

• Four sensitvity ranges

• Side-looking package

• Ideal for space-limited applicatons

• Ideal for PCBoard mountng

• Choice of clear, opaque or blue-tnted package

Applicatons:

• Applicatons requiring wide receiving angle

• Applicatons requiring PCBoard mountng

• Space-limited applicatons

• Optcal switches

• Optcal interrupt detectors

• Optcal encoders

• Non-contact positon sensing

• Machine automaton

OP552B属于传感器，变送器 > 光学传感器 - 光电晶体管。梯梯电子集成制造服务(苏州)有限公司制造生产的OP552B光学传感器 - 光电晶体管光电晶体管产品族中的产品是分立式光敏元件，其行为方式与双极晶体管相似，但使用入射光代替通过器件端子施加的电流来使器件导电。与光电二极管相比，光电晶体管通常会在相同强度的入射光下产生更大的输出电流，但对光强度的变化响应要慢。这些差异使光电晶体管的应用更为简单，但对于高速操作基本无用。
