PHOTOSWITCH R Photoelectric Sensors 42KA Actual Size Description The 42KA family of photoelectric sensor offers high performance sensing capability in a subminiature package. Intended for use in applications where small size is the key criteria, the 42KA is a practical alternative to using separate sensors and fiber optic cables. Two basic package styles are offered-- face view and side view. As seen in the illustrations above, the placement of the sensor optics determines the view. For the thinnest possible solution, the face view should be selected. Side view models have optics and connecting cable located on adjacent sides. For ease of selection, the 42KA is available in three sensing modes to cover most basic applications. Models are available with or without a sensitivity adjustment. Those models with this feature contain a cable mounted module to allow for the smallest possible sensor size.
