De scrip tion
The OPB380/390 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 0.125"
(3.18 mm) wide slot, the user can specify
(1) electrical output parameters, (2)
mounting tab configuration, (3) discrete
shell material, and (4) aperture width.
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 only on the
parallel faces inside the device throat)
are either IR transmissive plastic for
applications where aperture
contamination may occur or opaque
plastic with aperture openings for
maximum protection against ambient
light.
