Opto sensors meet strict hygiene standards

A Leuze Electronic product story
Edited by the Engineeringtalk editorial team Feb 29, 2008

The series 55's glass-free optic cover and the operating elements are absolutely leak-proof and gap-free.

Leuze's series 55 opto-sensors suits food and pharmaceutical processing lines, applications where strict hygiene regulations are enforced and there is the need for intensive cleaning and disinfection cycles.

The sensor has been developed around a build programme with an emphasis on ensuring that the glass-free optic cover and the operating elements are absolutely leak-proof and gap-free.

It uses a high-grade stainless steel V4A (316L) sensor housing, has an IP69K rating and is suitable for applications in elevated temperatures.

Applications include food processing, food filling, pharmaceuticals and cosmetics.

The series 55 stainless steel sensors are particularly useful in the wet areas of a production line, where the wash-down design makes it possible to thoroughly clean the entire system with all common cleaning agents and processes.

The nondiffusive and chemically resistant materials used in the optics and operational controls and the gap-free construction of the sensors prevent bacterial carry-overs.

Moreover, the enclosed housing technology and expanded temperature range from -20 to +70C combine to ensure long-lasting functionality.

The new 55 series of sensors is available in formats including throughbeam and retro-reflective models that are suitable for detection of clear film and glass or PET bottles, laser sensors for small parts as well as scanners including models with background suppression with high scanning rates.
