OP508F, OP509 Series OP509 OP508 Features: Flat lensed for wide acceptance angle (OP508F) Lensed for high sensitivity (OP509) Easily stackable on 0.100 (2.54 mm) hole centers Inexpensive plastic package Mechanically and spectrally matched to OP168 and OP268 series of infrared emitting diodes Description: Each device in the OP508F series consists of a NPN silicon phototransistor mounted in a flat, black plastic end -looking package. The flat sensing surface allows an acceptance half -angle of 60 when measured from the optical axis to the half power point. Each device in the OP509 series consists of a NPN silicon phototransistor mounted in a lensed, clear plastic end -looking package. The lensing eeff ct of the package allows an acceptance half -angle of 25 when measured from the optical axis to the half power point. OP508F and OP509 series devices can be mounted on 0.100 (2.54 mm) hole centers, which makes them an ideal low-cost alternate to hermetic OP600 sensors. OP508F and OP509 series devices are mechanically and spectrally matched to the OP168F and OP268F series of infrared emitting diodes. Please refer to Application Bulletins 208 and 210 for additional design information and reliability (degradation) data. For custom versions of the OP508F, OP509 and OP538F series devices please contact your OPTEK representative.
