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 rela vely even recep on over a large area. The

narrow receiving angle (25°) of the OP598 and OP798 series devices provides a rela vely small recep on area.

These devices are 100% produc on tested using infrared light for close correla on with OPTEK’s GaAs and GaAIAs emi ers.

Please refer to Applica on Bulle ns 208 and 210 for addi onal design informa on and reliability (degrada on) data.

Applications:

• Non-contact reflec ve or slo ed sensor

• Assembly line automa on

• Machine automa on

• Machine Safety

• End of travel sensor

• Door sensor

• Safety Curtain

Features:

• Dark blue epoxy package

• Wide receiving angle

• Variety of sensi vity ranges

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 plas cs.
