Low-frequency all-metal transponders from Contrinex 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, the food industry and aluminium processing.
>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 will withstand high-pressure cleaning with hot water and highly chemically active detergents or disinfectants. For these requirements, transponders are hermetically sealed in a one-piece stainless-steel housing with laser-welded backplate.
>The tags also work faultlessly in stainless steel environments - even when embedded with only the transponder face visible. In addition mechanical wear is practically non-existent.
