Hamamatsu Photonics THT LED Bernstein, Blau, Grün, Rot, 4-Pin

This family of light modulation ICs, from Hamamatsu, were developed for optical synchronous detections under disturbance background light. A monolithic photo IC chip contains a photodiode, preamplifier, comparator, oscillator, LED driver and signal processing circuit etc. Suitable applications include paper detection in office machines and optical switches.

Features of the light modulation photo ICs:
Large allowable background light level
Minimum detection level
Digital output
Small plastic package
Small hysteresis (S6809)
