PHOTOSWITCH R Photoelectric Sensors 42CB Description The 42CB family of photoelectric sensors shares many of the same features as the 42CA general purpose line but offer additional enhancements in electrical, mechanical, and optical characteristics. These include a faster response time, both light/dark operate modes, right angle package, dual LED outputs, sensitivity adjustment, and increased sensing range. The 42CB is available in three sensing modes to cover typical applications. The infrared light source provides excellent range for the sensor size. DC operation ensures compatibility with measurement and control circuits found in today's factory automation systems. Signaling of target detection is made via either an NPN or PNP output. This output is short-circuit protected to protect the sensor from possible damage. Light or dark operate condition is selected by wiring not model number.
