Description
The OPB360/370 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
(1) electrical output parameters, (2)
mounting tab configuration, (3) choice of
lead spacing, (4) discrete shell material,
and (5) 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 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.

C.
(2) RMA flux is recommended. Duration can be extended to 10 sec. max. when flow soldering.
(3) All parameters tested using pulse technique.
(4) Lead spacing of 0.220" (5.59 mm) or 0.320" (8.13 mm) is available. Leads are 0.20" sq. (5.08
mm) and 0.425" (10.80 mm) long (min).
(5) Methanol and isopropanol are recommended as cleaning agents. Plastic housings are
soluble in chlorinated hydrocarbons and ketones.
(6) Polarity is denoted by color of housing top:
LED - Gray or Clear
Sensor - Black
