Descripton:

Each device in the OP508F series consists of a NPN silicon phototransistor mounted in a flat, black plastc “end-looking” package. The flat sensing surface allows an acceptance half-angle of 60° when measured from the optcal axis to the half power point.

Features:

• Flat lensed for wide acceptance angle (OP508F)

• Lensed for high sensitvity (OP509)

• Easily stackable on 0.100” (2.54 mm) hole centers

• Inexpensive plastc package

• Mechanically and spectrally matched to OP168 and OP268 series of infrared emitng diodes

Applicatons:

• Applicatons requiring a wide acceptance angle

• Applicatons requiring high sensitvity

• Space-limited applicatons

OP509B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OP509B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。
