The OPB840 (L & W) series Slotted Optical Switch which provides the design engineer with the flexibility of a custom device from a standard product line. The L series a choice of PCBoard mount lead spacing, while the W series 24 (610mm) 26AWG wire leads. Building from a standard housing that utilizes a.375 (9.5mm) wide slot, user can specify the electrical output parameters, choice of aperture, discrete shell material, side mount configuration and a choice of lead spacing (for the L series) or 24 (610mm) UL approved 26 AWG wire leads (W series). Housings are made from an opaque grade of injection-molded plastic that minimizes the assembly's sensitivity to visible and near-infrared ambient radiation. Switching of the phototransistor occurs whenever an opaque object passes through the slot and interrupts the beam.
