OPV232
Description
The OPV232 is a high performance 850nm VCSEL pack-
aged for sensing applicat io ns. This product’s combina-
tion of features includi ng high speed, hig h out put power
and conc entric beam makes it an ideal transmitter for
integrat ion into all types of position sensing equipmen t.
Applications include:
Photoelect ric Sensors
Light Curtains
Position Sensors
Encoders
Maximum Forward Peak Current 30 mA
Maximum Reverse Voltage 5 Volts
Storage Temperature -40 to +125°C
Operating Temperature -40 to +85° C
Soldering Lead Temperature 260° C for 10 Seconds
Absolute Maximum Rating s (TA = 25° C unless otherwise noted)
Features
850nm VCSEL Technology
High thermal stability
Low drive current/high output intensity
Plastic T-1 convex lens for extra narrow beam
angle.
Additional laser safety information can be found
on the Optek website. See application #221.
Classification is not marked on the device due to
space limitations. See package outline for
centerline of optical radiance. Operating devices
beyond maximu m ratin g ma y result in hazardous
radiation exposure.

OPV232 Technical Data
NOTES:
(1) Threshold Current is based on the two line intersection method specified in Telcordia GR-468-Core. Line 1 from 6 mA to 8 mA. Line 2 from 0
mA to 2 mA.
(2) Series Resistance is the slope of the Voltage-Current line from 8 to 12 mA.
(3) Slope efficiency, is the slope of the best fit LI line from 8 mA above threshold to 12 mA.
Electrical/Optical Characteristics (at 25 °C unless otherwise specified)
Optek reserves the right to make changes at any time in order to improve design and to supply the best product possible.
