Magnetic Dallas iButton TM1990A-F5 for EPOS/Cash Registers/Tills

The MT1990A Magnetic iButton Fob consists of a nickel-plated steel ring pushed over an iButton (TM1990A), which is inserted into a plastic fob. When this fob is held close to the front face of the Magnetic Probe, it is pulled onto the probe’s face by the magnetic force exerted on the steel ring, and held firmly in place.

The iButton serial number (TM1990A) is a rugged data carrier that serves as an electronic registration number for automatic identification. Data is transferred serially through the 1-Wire protocol, which requires only a single data lead and a ground return. Every TM1990A is factory lasered with a guaranteed unique 64-bit registration number that allows for absolute traceability. The durable stainless-steel iButton package is highly resistant to environmental hazards such as dirt, moisture, and shock. Its compact coin-shaped profile is self-aligning with mating receptacles, allowing the TM1990A to be used easily by human operators. Accessories enable the DS1990A to be mounted on almost any object, including containers, pallets, and bags.
