The W24 features a rugged metal housing that has passed IP 69K testing, which ensures reliability in harsh industrial conditions. These sensors are highly resistant to ambient light and offer a very long sensing range with a high operating reserve. As a result, there are optional a standard front lens heating or a high-power front lens heating versions, similar to automotive rear window defrost, for use in environments with extreme temperatures fluctuation. An alarm output option enables early detection of contamination, reducing downtime that results from contamination interruptions. Variants with DC voltage and universal voltage DC/AC and multiple connectivity options provide additional flexibility within the W24 family.
