OPB845L51 [TT Electronics]

OPB830 and OPB840 series are slotted optical switches that provide flexibility for custom device requirements. They feature a standard housing with a 0.375” (9.5 mm) wide slot, and users can specify electrical output parameters, aperture choice, discrete shell material (IR transmissive or opaque), side mount configuration, and lead spacing (L Series) or 24” (610 mm) 26 AWG wire leads (W Series). The housing is made from opaque injection-molded plastic to minimize sensitivity to ambient light. The discrete shells are available in IR transmissive plastic for contamination-prone environments or opaque plastic with aperture openings for maximum ambient light protection. The phototransistor switches when an opaque object interrupts the beam.
