The OPB830W55Z is a panel/chassis remote-mount Slotted Optical Switch with phototransistor output. It offers 24-inch 26AWG wire interconnect. It provides the design engineer with the flexibility of a custom device from a standard product line. The transmissive photo interrupter housing is made from a side mount IR transmissive discrete shell that minimizes the assembly sensitivity to visible and near-infrared ambient radiation. Discrete shell is made of either IR transmissive plastic for applications where aperture contamination may occur.
