By adding an external photodiode, an IR LED, two PNP power transistors and a minimum of other parts, the AM 336 will be a complete optoelectronic interface (proximity and barrier) for a reflective optical proximity switch or for a light barrier with external synchronisation. APPLICATIONS • Miniaturised One Way Light Barrier • Miniaturised Reflection Light Barrier • Frame Light Barrier BLOCK DIAGRAM Figure 1: Block diagram of AM336 IRD VCC VZ CSC RS QC QO LED RD RH GND INA ALR OUTA IND P/B FO oscillator T SYNC amplifier signal detection :128 T1 T2 short circuit pulse regulation current regulation output driver T1 T2 SC B A LED driver A B SC LED XX L T1 LL H HH H H H L T2 H L zener diode X X :4 |
