PS-117L Overview
Paper sensors PS-117L °§ PS-117D DIMENSIONS The PS-117 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-117D : Low level output at shielding (Unit.
