Descriptions:The DS104 (Slot Optical Switch) is a gallium arsenide infraredemitting diode which is coupled with a silicon photo transistorin a plastic housing. The packaging system is designed to optimizesthe mechanical resolution, coupling efficiency, and insulatesambient light. The slot in the housing a provides a means ofinterrupting the signal with printer, scanner, copier, or otheropaque material, switching the output from an ” ON” to” OFF”state. Features:Wide gap between light emitter and detector(4.0mm)High sensing accuracyPWB mounting type package Applications:CopierPrinterFacsimileTicket vending machineOpto-electronic switch<strong>TAT</strong> <strong>ELECTRONICSCO</strong>.,<strong>LTD</strong>
