PS-R11L Overview
Paper sensors PS-R11 L °§ PS-R11D DIMENSIONS The PS-R11 photo switches are posed 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. High level output at shielding PS-R11D : Low level output at shielding (Unit.
