Light in Motion has released the QSE258: a logic output photosensor.  Owing to an open-collector output, multiple units can be tied in a logic "AND" function, allowing simultaneous multiple objects sensing.

The device consists of a photodiode, a linear amplifier, a voltage regulator, a Schmitt trigger and an open collector output transistor. The Schmitt trigger provides hysteresis for noise immunity and pulse shaping. The open collector output allows interfacing with various logic level circuits. Packaged in a leaded sidelooker package with daylight filter.


  • Sidelooker package
  • High Noise Immunity
  • Buffer Open Collector
  • Reception Angle 50°
  • RoHS compliant
