IP eingestellt uber den Durchlastrom der Sendediode, den Reflexionsgrad und den Abstand des Reflektors vom Bauteil (d) IP as a function of the forward current of the emitting diode, the degree of reflection and the distance between reflector and component (d)
Es wird empfohlen die Lichtschranke bei dem spezifizierten Arbeitpunkt von ca. 8mA fur den Emitter einzusetzten, weil andere Betriebsstrome zu einem groeren Streubereich beim Koppelfaktor fuhren. Der Abgleich erfolgt uber den Arbeitswiderstand am Detektor. Von einem Einsatz der Lichtschranke mit glanzenden oder gar spiegelnden Oberflachen wird abgeraten. Die Abstrahlcharakteristik des Senders andert sich sowohl uber die Temperatur als auch mit dem Flustrom starker als bei Standardemittern und fuhrt somit ebenfalls zur Erhohung des Streubereichs beim Koppelfaktor. Bei diffuser Streuung ist dieser Einflu jedoch gering, und kann fur die meisten Anwendungen vernachlassigt werden.

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.
