Luna Optoelectronics NSL-19M51

CdS cell, NSL series, SilonexLight dependent resistors are two cadmium sulphide (cDS) photoconductive cells with responses similar to that of the human eye. The cell resistance falls with increasing light intensity. Solid-state photosensor that uses photoconductivity to lower resistance value when irradiated with light Ceramic package with sensitivity up to 690 nm TO-5 and TO-18 packages Suitable for use in applications like street light auto-flashers and camera light metres ### Applications Applications include Smoke detection Automatic lighting Control batch counting Burglar alarm systems ### 光电二极管，Silonex
