Leuze electronic Series 53 and 55 washable optoelectronic sensors

The Wash-Down and Hygiene design sensor series from Leuze electronic are designed for frequent and intensive cleaning and disinfection cycles.

Leuze electronic developed these sensors as the equivalent to its standard 3B series sensors designed for dry applications, featuring scalable housing technology. Their V4 stainless steel housings make them suitable for areas in which intensive cleaning and disinfection cycles take place.

The sensors comply with the requirements set out by Ecolab, IP67, IP69K and also Leuze’s own CleanProof+ standards. In contrast to the 55 series, the series 53 sensors are missing the customary fastening holes in a bid to eliminate any last foothold for the accumulation of dirt deposits. Instead they feature a fitting at the cable terminal acting as a gas-tight adapter. The hygiene design of the optosensor series 53 has also been certified by the Weihenstephan Research Centre for Brewery and Food Quality at the Technical University of Munich in accordance with EHEDG recommendation no. 8 (Hygienic Equipment Design Criteria). On principle, this qualification includes the requirements imposed by standards DIN EN 1672-2: 2005, DIN EN ISO 14159:2004 and the Machine Directive 98/37/EEC, as well as the revised version 2006/42/EEC.
