Self-contained subminiature flat pack photoelectric sensors are ideal for applications short-range sensing applications where compact size is a primarily concern. The fast 500 us response time and compact size make them a practical and low cost alternative to split solution sensors using a separate amplifier and fiber optic cable. Most sensors are available with or without a sensitivity adjustment. Models without sensitivity adjustment are useful for applications where maximum range is required and minimal adjustments are preferred. The adjustable models feature a unique cable mounted sensitivity adjustment to allow for the smallest possible size with sharp cut-off diffuse, red LED, light operate, PNP output, side view.
