OP550, OP552, OP555, OP750, OP755, OP770 and OP775 series consists of a NPN silicon phototransistor molded in an
epoxy package with a wide receiving angle that provides relaƟvely even recepƟon over a large area. The OP750, OP755,
OP770 and OP775 have addiƟonal circuitry to enhance the operaƟon of the device for stray light levels.
OP560 and OP565 series consists of a NPN silicon photodarlington transistor molded in an epoxy package with a wide
receiving angle that provides relaƟvely even recepƟon over a large area.
The side-looking package design allows easy PCBoard mounƟng of sloƩed opƟcal switches or opƟcal interrupt detectors.
The OP550, OP560, OP750 and OP770 devices have an external lens in a clear epoxy package.
The OP552 device has an integral lens in an opaque plasƟc package that is opƟcally transparent to infrared light but opaque
to visible wavelengths. This feature allows the device to be used under high ambient light condiƟons – or anywhere
external light sources could interfere with the intended sensing applicaƟon (visible light immunity).
The OP555, OP565, OP755 and OP775 devices have an internal lens in a blue-Ɵnted package. The lensing eīect of this
package allows an acceptance half-angle of 28° when measured from the opƟcal axis to the half-power point.
These devices are 100% producƟon tested using infrared light for close correlaƟon with OPTEK’s GaAs and GaAIAs emiƩers.
All of these sensors are mechanically and spectrally matched to the OP140, OP142, OP145, OP240 and OP245 series of
infrared emiƫng diodes.
Please refer to ApplicaƟon BulleƟns 208 and 210 for addiƟonal design informaƟon and reliability (degradaƟon) data.
