Sensing and Control Reflective Object Sensor OPB608A, OPB608B, OPB608C, OPB608R, OPB608V Features: Phototransistor output Unfocused for sensing di use surface Low cost plas c housing Enhanced signal to noise ra o Reduced ambient light sensi vity Descrip on: OPB608 reec ve switches consist of an infrared emi ng device (LED or VCSEL) and a NPN silicon phototransistor mounted side- by-side on a parallel axis in a black opaque plas c housing. All OPB608s (except OPB608R) have an emi ng device and a phototransistor that are encapsulated in a visible ltering epoxy. The phototransistor responds to radiaon from the emi er only when a reec ve object passes within its eld of view. The phototransistor has enhanced low current roll-o to improve the contrast ra o and immunity to background irradiance. LED versions are designed for near- eld applica ons. The VCSEL version is designed for longer distances. OPB608A, OPB608B and OPB608C devices are designed for applica ons with reec ve distances between 0.050 (1.270 mm) and 0.375 (9.525 mm). OPB608V is designed for applica ons with re ec ve distances between 0.050 (1.270 mm) and 1.200 (30.480 mm). All of these are designed for light pa erns not visible to the human eye. By ulizin g the night enhancement funcon of a camera, the near infrared light pa ern can be seen. This allows a user to see the pa ern shining on the reec ve object. OPB608R is designed for applica ons with re ec ve distances between 0.050 (1.270 mm) and 0.300 (7.620 mm). It is designed for light pa erns visible to the human eye. The eciency of this sensor is lower for opcal wavelengths in the visible range, thus reducing the distance that can be used. Reec ve distances are depen dent upon the drive current for the light emi ng device, the wavelength of the light source, and the type of reec ve material therefore, each applica on should be checked for the ability to meet each requirement. Custom electrical, wire and cabling and connectors are available. Contact your local representave or OPTEK for more informa on.
