Description:

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 relatively even reception over a large area. The OP750 and OP770 have additional

circuitry to enhance the operation 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 relatively even reception over a large area.

The side-looking package design allows easy PCBoard mounting of slotted optical switches or optical 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 plastic package that is optically transparent to infrared light but opaque

to visible wavelengths. This feature allows the device to be used under high ambient light conditions – or anywhere

external light sources could interfere with the intended sensing application (visible light immunity).

The OP555 and OP565 devices have an internal lens in a blue-tinted package. The lensing effect of this package allows an

acceptance half-angle of 28° when measured from the optical axis to the half-power point.

These devices are 100% production tested using infrared light for close correlation with OPTEK’s GaAs and GaAIAs emitters.

All of these sensors are mechanically and spectrally matched to the OP140, OP142, OP145, OP240 and OP245 series of

infrared emitting diodes.

Please refer to Application Bulletins 208 and 210 for additional design information and reliability (degradation) data.

For custom versions please contact your OPTEK representative.
