OP644SL NPN Silicon Phototransistor

Features:
 Narrow receiving angle
 Variety of sensitivity ranges
 Enhanced temperature range
 PC Board Mounting
 Mechanically and spectrally matched to OP123 and OP223 LEDs
 TX and TXV processing available (see Hi-Rel section)

Description:
Each device in this series is a NPN silicon phototransistor in a hermetically sealed pill package. The narrow receiving angle
provides excellent on-axis coupling
The OP644SL series devices are 100% production tested using infrared light for close correlation with OPTEK GaAs and GaAIAs
emitters. Components in the OP644SL series are mechanically and spectrally matched to the OP123 and OP233 series
TX and TXV components are available. For more information, please contact your local representative or OPTEK.
Please refer to Application Bulletins 208 and 210 for additional information and reliability (degradation) data, and to
Application Bulletin 202 for pill-type soldering to PC Board.

Applications:
 Non-contact reflective object sensor
 Assembly line automation
 Machine automation
 Machine safety
 End of travel sensor
 Door sensor
