Description
The 42KD Miniature sensor provides a solution for applications in very
small confined spaces. The 42KD sensor is the smallest sensor in the
Photoelectric sensor portfolio. It offers various sensing modes, sensing
distances, auto PNP/NPN, push button/remote teach, and push
button lock options. Although miniature in size the features and
performance on this sensor are reliable and competitive.
The 42KD is available in visible red LED models in polarized
retroreflective and fixed/adjustable background suppression sensing
modes. The teach button simplifies the setup process and even
provides the option to remote teach the sensor. The sensor also has
the option of light operate (L.O.) or dark operate (D.O.). All 42KD
sensors have a unique "auto PNP/NPN" output which reduces stocking
cost and simplifies selection, installation, and maintenance.
The 42KD is an excellent solution to a broad range of applications
including industries such as automotive, packaging, and material
handling. These features make the 42KD sensor easy to apply in
challenging applications, especially where space is a limitation.
