Description
The OPB819 consists of an infrared
emitting diode and NPN silicon
phototransistor mounted in a plastic
houising on opposite sides of a 1.25”
(31.75 mm) wide slot. Phototransistor
switching takes place whenever an
opaque object passes through the slot.
Custom electrical, wire or cabling is
available.
Contact your local representative or

NOTES:
(1) Derate linearly 1.67 mW/°C above 25°C.
(2) All parameters tested using pulse technique.
Precautions:
Exposure of the plastic body to chlorinated hydrocarbons and ketones such as
thread lock and instant adhesive products will degrade the plastic body. Cleaning agents
methanol and isopropanol are recommended. Spray or wipe do not submerge.
