PHOTOSWITCH R Photoelectric Sensors 42CA Description The 42CA is a family of general purpose photoelectric sensors intended for light to medium duty industrial applications. They are packaged in an industry standard 18mm cylindrical housing. General Specifications Light Source For ease of maintenance, there are no user adjustments required. A single red LED provides a visual indication of the output status. As an alternative to the 18mm cylindrical package, Rockwell Automation/Allen-Bradley also offers the RightSight photoelectric sensor. That product is of a right angle design to conserve space in many applications. Refer to page 1-31 for further information on this product. Infrared 880nm Unit Protection Reverse polarity, output short-circuit protection (SCP) Supply voltage 10-30V DC Current Consumption Output Type The 42CA 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 model number.
