Description:
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 uꢂlizes a .375” (9.5 mm) wide slot, a user can specify the electrical output
parameters, choice of aperture, discrete shell material, side mount conꢁguraꢂon, 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 injecꢂon-molded plasꢂc that minimizes the assembly’s sensiꢂvity to visible and
near-infrared ambient radiaꢂon. Discrete shells (exposed on the parallel faces inside the device throat) are made of either
IR transmissive plasꢂc (for applicaꢂons where aperture contaminaꢂon may occur) or of opaque plasꢂc with aperture
openings (for maximum protecꢂon against ambient light).
Switching of the phototransistor occurs whenever an opaque object passes through the slot and interrupts the beam.
