* Der Emitter wird mit 10mA gepulst betrieben; das bedeutet, dass jeder Widerstand in Serie zu Vcc

einen Spannungsabfall in der Versorgungsleitung verursacht. Daher wird empfohlen, diesen

Serienwiderstand kleiner 10 Ohm zu halten. Die minimale Versorgungsspanung (Vcc min ) darf keinesfalls

unterschritten werden.

* The emitter is driven with 10 mA in pulsed mode; this means that any series resistor to Vcc causes a

voltage drop on the power line. It is recommended to keep the series resistor below 10 Ohm. The supply

voltage may not fall below Vcc min

Startverhalten und Ablaufdiagramm

Start-up behavior and Timing diagramm

Der Ausgang ist immer hochohmig, wenn an Vcc keine Spannung angeschlossen ist. Wenn die Versorgungsspannung

Vcc , start erreicht, bleibt der Ausgang für 60ms <tstart <120ms auf „low“. Anschließend findet etwa alle 90ms eine

Messung der Orientierung statt und der Ausgang wird entprechend geschalten.

The Output is always high ohmic when voltage at Vcc is not connected. When supply voltage reaches Vcc, start the

sensor output stays low for 60ms <tstart <120ms. Subsequently approx. every 90ms the orientation is measured and

the output is set accordingly.
