Transponder Area of application
MDS D400 Simple identification such as electronic barcode replacement/supplements, from warehouse and
distribution logistics right through to product identification.
MDS D421 The MDS D421 is designed for tool coding according to DIN 69873.
It can be used wherever small data carriers and exact positioning are required, e.g. tool identification,
workpiece holders
MDS D422 Identification of metallic workpiece holders, workpieces or containers
MDS D423 Identification of metallic workpiece holders, workpieces or containers, production automation
MDS D424 Production and distribution logistics as well as in assembly and production lines
MDS D425 Compact and rugged ISO transponder; suitable for screw mounting.
Use in assembly and production lines in the powertrain sector; ideal for mounting on motors, gearboxes,
and workpiece holders
MDS D426 Compact and rugged ISO transponder; suitable for identification of transport units in production-related
logistics; can also be deployed in harsh conditions
MDS D428 Compact and rugged ISO transponder; suitable for screw mounting
Use in assembly and production lines in the powertrain sector
MDS D460 Assembly lines with very small workpiece holders
