0.125” (3.18 mm) wide gap
Choice of mounting configuration
De scrip ion
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” (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’s sensitivity to ambient
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.
