Silicon Photodetector with Logic Output
Description
TEKS5412 is a high sensitive photo Schmitt Trigger in a
sideview molded plastic package with spherical lens. It is
designed with an infrared filter to spectrally match to
GaAs IR emitters (
l
p
=950nm).
The photodetector is case compatible to the TSKS5412
GaAs IR emitting diode, allowing the user to assemble his
own optical sensor.
Features
D Very high photo sensitivity
D Supply voltage range 4.5 to 16 V
D Low current consumption ( 2 mA )
D Side view plastic package with lens
D Angle of half sensitivity
=
30
D TTL and CMOS compatible
D Open collector output
D Output signal inverted ( active "low" )
D Case compatible with TSKS5412
D Option X01: High rel. device for advanced
applications
D Taped and reeled according to IEC 286 part 2
D Packing AMMOPACK: 2,000 pcs
D Ordering code number: TEKS5412X01ASZ
D Visual inspection according to QSV 5610
