OPB840W55 [TT Electronics]

OPB830 and OPB840 series provide the design engineer with the flexibility of a custom device from a standard product line. The L Series offers a choice of PCBoard mount lead spacing, while the W Series offers 24” (610mm) 26AWG wire leads. Building from a standard housing that utilizes a .375” (9.5 mm) wide slot, a 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” [610 mm] 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. Discrete shells (exposed on the parallel faces inside the device throat) are made of either IR transmissive plastic (for applications where aperture contamination may occur) or of opaque plastic with aperture openings (for maximum protection against ambient light). Switching of the phototransistor occurs whenever an opaque object passes through the slot and interrupts the beam.
