Description:
Each device in this series consists of an NPN silicon phototransistor molded in a dark blue epoxy packages. The wide
receiving angle (130°) of the OP593 and OP793 series devices provides relaƟvely even recepƟon over a large area. The
narrow receiving angle (25°) of the OP598 and OP798 series devices provides a relaƟvely small recepƟon area.
These devices are 100% producƟon tested using infrared light for close correlaƟon with OPTEK’s GaAs and GaAIAs emiƩers.
Please refer to ApplicaƟon BulleƟns 208 and 210 for addiƟonal design informaƟon and reliability (degradaƟon) data.
Applications:
• Non-contact reflecƟve or sloƩed sensor
• Assembly line automaƟon
• Machine automaƟon
• Machine Safety
• End of travel sensor
• Door sensor
• Safety Curtain

To avoid stress cracking, we suggest using
ND Industries’ Vibra-Tite for thread-locking.
Vibra-Tite evaporates fast without causing structural failure in
OPTEK'S molded plasƟcs.
