PHOTOSWITCH R Photoelectric Sensors 42KB Description The 42KB family of photoelectric sensor offers high performance sensing capability in a compact rectangular package. Like the 42KA family, the 42KB is intended for use in applications where small size is the key criteria. Two basic package styles are offered-- end view and side view. As seen in the illustrations above, the placement of the sensor optics determines the view. End view sensors have the optics and cable located at opposite ends while side view sensors are located on adjacent sides. For increased application flexibility, the 42KB is available in four sensing modes to cover a variety of applications. A single-turn sensitivity adjustment is provided on each sensor for setting the sensor during the installation phase.

Both a Light Source (Emitter) and Receiver are included in the package. To identify the Light Source, replace the "T" in the catalog number with "E." To identify the receiver, replace the "T" in the catalog number with "R." Example: 42KA-T2KNHK-A2 contains one 42KA-E2KNHK-A2 Light Source and one 42KA-R2KNHK-A2 Receiver.
