The slotted optical sensors in this series provide the flexibility of a custom device from a standard product line. Building from a standard housing with a 0.125 inch (3.18mm) wide slot, the user can specify output logic state, output driver circuit, aperture width, aperture surface and mounting tab locations. The device body is an opaque plastic which minimizes sensitivity to both visible and near-infrared external light sources. Aperture width choices provide different optical resolution for motion sensing. A covered aperture provides dust protection, while an open aperture provides maximum protection against external light sources. LED emissions are near-infrared (850-940nm).
