Paper sensors KODENSHI PS-R50L・PS-R50D DIMENSIONS (Unit : mm) The PS-R50 photo switches are composed of a modulated infrared emitting diode at the light-emitting side and a modulated photo IC (in which a photodiode,signal processing circuit,constant voltage circuit and modulation circuit are integrated) at the light receiving side. PS-R50L : High level output at shielding PS-R50D : Low level output at shielding FEATURES •High-speed response(0.5m sec.) •Adjustable of detecting distance •Resistible to exterior light because of composed of modulate APPLICATIONS •Copiers •Facsimiles MAXIMUM RATINGS (Ta=25℃) Item Symbol Rating Unit Supply voltage Output voltage *1 Low level output current *2 Output transistor power dissipation Operating temp. *3*4 Storage temp. *3*4 VCC VO IOL PO Topr.
