TM1990A-F5 Ibutton

TM1990A-F5 Ibutton

The TM1990A-F5 IButton is a rugged and compact contact device built into a durable ABS housing. It is based on the TM (or DS) series 1-Wire / iButton architecture. Unlike flat RFID cards, the iButton is a small “button” form factor that users can physically carry, attach, or insert into holders for identification or authentication purposes.

Key features and traits:

  • Housing: ABS plastic shell providing mechanical protection
  • Chip: TM1990A-F5 (compatible with DS1990A / iButton 1-Wire standard)
  • Dimensions: ~16.25 mm (diameter) × 5 mm thickness (as per your spec)
  • Connector: Stainless steel contact on the surface for electrical interface
  • Communication: 1-Wire protocol (standard iButton interface)
  • Unique ID: Each iButton has a factory programmed unique identifier (UID) used for authentication
  • Durability: Designed for many cycles of contact, robust against wear and environmental factors

This device is a hybrid between mechanical and electronic token: you touch it to a reader contact, and the reader reads the unique ID to grant access or record data.
