Choice of mounting configuration
Description
The OPB355 series of slotted switches
provides the design engineer with the
flexibility of a custom device from a
standard product line. Building from a
standard housing with a .125鈥?3.18 mm)
wide slot, the user can specify the
mounting tab configuration.
The photodiode output provides a lower
but more linear output vs. light input
when compared to slotted switches with
a standard phototransistor output.
All housings are an opaque grade of
injection molded plastic to minimize the
assembly鈥?sensitivity to ambient
s
radiation, both visible and near-infrared.
Discrete shells (exposed on the parallel
faces inside the device throat) are IR
transmissive plastic for applications
where aperture contamination is a
concern.
Custom electrical, wire and cabling is
available. Contact your local
representative or Optek for more
information.

NOTES:
(1) Derate linearly 1.67 mW/擄C above 25擄C.
(2) RMA flux is recommended. Duration can be ex tended to 10 sec. max. when flow soldering.
(3) All parameters tested using pulse technique.
(4) Polar ity is denoted by color of housing top:
LED - Clear
Sensor - Black
PRECAUTIONS:
Exposure of the plastic body to chlorinated hydrocarbons and ketones such as
thread lock and instant ad hesive products will degrade the plastic body. Cleaning agents
methanol and isopropanol are recommended. Spray or wipe do not submerge.
