Photoreflectors slim to detect
NJL5190K/5192K photoreflectors feature a miniature, thin double-cavity package that comprises an IR LED on one side and a high-sensitivity silicon photoreflector transistor on the other side.
NJL5190K/5192K general-purpose photoreflectors, manufactured by New Japan Radio and available from Young ECC feature a miniature, thin double-cavity package that comprises an IR LED on one side and a high-sensitivity silicon photoreflector transistor on the other side An object that approaches the device reflects light and, consequently, affects the phototransistor output due to its proximity

Infra-red remote control receivers
Small, high-performance receivers for infra-red remote control systems, NJL65V/68H000 series parts feature a metal case with mesh window, which dramatically improve EMI characteristics.
Competitively priced, the NJL5190K/5192K photoreflector is part of a wider range comprising various series and types.
Featuring a small package, it suits a broad range of applications, including end detection of video or audio tape, coin mechanisms, reading film information and mechanism timing in cameras, rotation detection and control of motors, as well as paper edge detection and mechanism timing detection in facsimile printers and x-y recorders.
Suitable for industrial use, the photoreflectors can also be used in robotics and reading out characters in barcode readers, encoders and automatic vending machines.
Features include a built-in visible light cutoff filter, high output and high signal-to-noise ratio.
Total power dissipation is 60mW and operating temperature is -20 to 85C.
The emitter forward current (continuous) typically comes in at 4mA, while the output current is typically 100uA with a reflective surface 0.7mm away and rise and fall times of 30us.
The output current can typically reach 300uA with an emitter current of 10mA.
