Introducing the TM1990A-F5 electronic iButton key, a premium, unparalleled analog of the renowned Dallas/Maxim DS1990A-F5 iButtons. Crafted specifically for access control systems, each key boasts a unique 64-bit code and an exclusive family code embedded during production, ensuring it remains immutable and uncompromisable.
During production, this cutting-edge device is endowed with a distinct identification code comprised of alphanumeric characters, directly integrated into the production line. With approximately 4 billion possible combinations, the likelihood of unauthorized access is nearly non-existent. The key is engineered to resist charge or magnetizing, yet facilitates seamless storage within the memory controller, orchestrating entry to secure premises.
Engage the iButton reader with the TM1990A-F5 key, and witness as it transmits the embedded code to the controller. The system meticulously verifies the presence of this identifier within its database. Upon successful matching, it evaluates access rights-accounting for any potential time limitations-and authorizes the actuators, such as locks or relays, to execute open/close commands.
Key Advantages of the TM1990A-F5: These electronic keys guarantee absolute uniqueness, streamlining the process and cost-efficiency of programming extensive arrays of keys for personnel. Please note, the TM1990A-F5 is not designed for duplication purposes. For duplication requirements, please utilize our RW1990 copy iButtons, suitable for replicating DS1990A and TM1990A keys.
