Der Abgleich erfolgt über den Arbeitswiderstand am Detektor. Von einem Einsatz der Lichtschranke mit glänzenden oder gar spiegelnden Oberflächen wird abgeraten. Die Abstrahlcharakteristik des Senders ändert sich sowohl über die Temperatur als auch mit dem Flußstrom stärker als bei Standardemittern und führt somit ebenfalls zur Erhöhung des Streubereichs beim Koppelfaktor. Bei diffuser Streuung ist dieser Einfluß jedoch gering, und kann für die meisten Anwendungen vernachlässigt werden. 1) Anm.: Note: It is recomended to use the interrupter at the specified emitter current of about 8mA, as other operating currents lead to a larger coupling factor variation. The tuning is done using the operating resistor on the detector side. It is not recomended to use the interrupter in combination with shiny or mirror like surfaces. Changes in temperatures and operating current are having a bigger influence on the radiation characteristic as it is the case for standard emitters. This means a higher variance of the coupling factor. For diffuse surfaces the mentioned influence is low, and can be neglected for most of the applications. 2004-08-30 5 SFH 9221 pPhotocurrent --------I p max Kodak 90% 1.2 I C;rel 1.0 0.8 0.6 0.4 0.2 0.0 0 5 10 15 mm 20 d I = f(d) Relative Spectral Sensitivity Dark Current Max.
