Contrinex stainless steel RFID tags

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.

The read/write modules and tags (125 kHz, operating frequency: 31.25 kHz) have an IP68 protection rating and can therefore be used even underwater. 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 a one-piece stainless steel housing with a laser-welded backplate.

They also work faultlessly in stainless steel environments — even when embedded with only the transponder face visible. Mechanical wear, for example from aluminium chips or dirt particles, is practically non-existent.

The transponders are suitable for an operating temperature range of -40°C to 180°C.
