TT OPB608R
OPB608R is designed for applications with reflective distances between 0.050” (1.270 mm) and 0.300” (7.620 mm). It is designed for light patterns visible to the human eye. The efficiency of this sensor is lower for optical wavelengths in the visible range, thus reducing the distance that can be used.| Part No. | OPB608R |

DESCRIPTION
: OPB608 reflective switches consist of an infrared emitting device (LED or VCSEL) and a NPN silicon phototransistor mounted “side-by-side” on a parallel axis in a black opaque plastic housing. All OPB608’s (except OPB608R) have an emitting device and a phototransistor that are encapsulated in a visible filtering epoxy. 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. LED versions are designed for near-field applications. The VCSEL version is designed for longer distances. OPB608A, OPB608B and OPB608C devices are designed for applications with reflective distances between 0.050” (1.270 mm) and 0.375” (9.525 mm). OPB608V is designed for applications with reflective distances between 0.050” (1.270 mm) and 1.200” (30.480 mm).
