42CF Series Photoelectric Sensor Specifications and Installation Guide

This document provides specifications, installation instructions, and alignment procedures for the 42CF family of general-purpose photoelectric sensors, which are packaged in a 12mm cylindrical housing for light to medium duty industrial applications. It covers three sensing modes (transmitted beam, diffuse, and polarized retroreflective), output types (NPN/PNP), and features such as short-circuit protection, reverse polarity protection, teach and remote-teach functions, and fine adjustment for semi-transparent objects.
