Contrinex offers low frequency all-metal RFID transponders that are resistant to metal chips, dirt, alkaline cleaning agents and hot water. They withstand wash-down processes undamaged and are recommended for use in construction machines, cement works, food industry and aluminium processing. In situations too challenging for standard RFID components, stainless steel RFID transponders come into their own: Low-frequency all-metal read/write modules and tags have an IP68 protection rating and can, therefore, be used even under water. Models additionally rated to IP69K, a normal protection type for food industry use, will withstand high-pressure cleaning with hot water and highly chemically active detergents or disinfectants, such as hydrogen peroxide and products with alkaline or chlorine content. For these requirements, transponders are hermetically sealed in one-piece stainless-steel housing with laser-welded backplate. However, aggressive cleaning agents are not alone in having no influence on low-frequency all-metal transponders. They also work faultlessly in stainless steel environments - even when embedded with only the transponder face visible.
