Reflective Object Sensor
OPB608A/B/C, OPB608R, OPB608V
Phototransistor Output
Unfocused for sensing diffuse surface
Low Cost Plastic Housing
Enhanced signal to noise ratio
Reduced ambient light sensitivity
The OPB608 is a reflective switch that consist of an infrared emitting device (LED or VCSEL) and an NPN silicon phototransistor mounted
“side-by-side” on a parallel axis in a black opaque plastic housing. Both the emitting device and phototransistor are encapsulated in a visible
filtering epoxy except the OPB608R. The phototransistor responds to radiation from the emitter only when a reflective object passes within its
field of view. The phototransistor has enhanced low current roll off to improve the contrast ratio and immunity to background irradiance. The
LED versions are designed for near field applications with the VCSEL version being designed for longer distances.
The OPB608A/B/C devices are designed for applications with reflective distances between 0.050” and 0.375” and when the light pattern is not
to be seen by the human eye except for the OPB608R. By utilizing the night enhancement function of a camera, the near infrared light pattern
can be seen. This allows the user to see the pattern shining on the reflective object.
The OPB608R device is designed for applications with reflective distances between 0.050” and 0.300” and when the light pattern is to be seen
by the human eye. The efficiency of the sensor is lower for optical wavelengths in the visible range thus reducing the distance that can be
used.
The OPB608V device is designed for applications with reflective distances between 0.050” and 1.5” and when the light pattern is not to be seen
by the human eye. By utilizing the night enhancement function of a camera, the near infrared light pattern can be seen. This allows the user to
see the pattern shining on the reflective object.
Reflective distances are dependent upon the drive current for the light emitting device, the wavelength of the light source, and the type of re-
flective material, therefore each application should be checked for the ability to meet each application.
Optek reserves the right to make changes at any time in order to improve design and to supply the best product possible.

space limitations. See package outline for
centerline of optical radiance. Operating de-
vices beyond maximum rating may cause de-
vices to exceed rated classification
