Proximity Switches

Series 520 inductive proximity switches incorporate technology to provide a lengthy operating distance.

The switches operate at 25 to 70°C, are compatible with most standard proximity switches, and are suitable for targets normally hard to detect such as small or narrow objects, nonferrous metals, and wires. The Series includes N.O. and N.C. types and pnp and npn configurations, in cable or connector versions. The quasi-embeddable devices come in M8 and M12 sizes and feature short-circuit protection and EMC and polarity-reversal protection.
