NPN Silicon Phototransistor OP508F, OP509, OP538F Series OP509 OP508, OP538F Features: Flat lensed for wide acceptance angle (OP508F) Lensed for high sensi vity (OP509) Easily stackable on 0.100 (2.54 mm) hole centers Inexpensive plas c package Mechanically and spectrally matched to OP168 and OP268 series of infrared emi ng diodes Description: Each device in the OP508F series consists of a NPN silicon phototransistor mounted in a at, black plas c end-looking package. The at sensing surface allows an acceptance half-angle of 60 when measured from the op cal axis to the half power point. Each device in the OP509 series consists of a NPN silicon phototransistor mounted in a lensed, clear plas c end-looking package. The lensing e ect of the package allows an acceptance half-angle of 25 when measured from the op cal axis to the half power point. Each device in the OP538F series consists of a NPN silicon photodarlington mounted in a at, black plas c end-looking package. The at sensing surface allows an acceptance half-angle of 65 when measured from the op cal axis to the half power point. OP508F, OP509 and OP538F series devices can be mounted on 0.100 (2.54 mm) hole centers, which makes them an ideal low-cost alternate to herme c OP600 sensors. OP508F, OP509 and OP538F series devices are mechanically and spectrally matched to the OP168F and OP268F series of infrared emi ng diodes.
