iButton Serial-Number Keys

Read-only 64-bit ROM keys — the standard credential for access control and intercoms.

The industry-standard 64-bit ROM key in the F5 can.

Same silicon as F5 in the slimmer 3.1 mm F3 can for flush mounting.

R-variant that guarantees a presence pulse the instant the key touches a live bus.

Cost-optimised DS1990A equivalent — the volume workhorse for intercom keys.

DS1990A key pre-assembled into a magnetic-ring key fob.
