Description
The RBH‑PROX‑KT‑50 is a compact 125 kHz proximity key fob built for RBH access control systems, offering a practical alternative to full‑size cards. Molded from durable ABS plastic in a teardrop shape, it’s small enough to fit comfortably on a key ring yet tough enough to withstand daily handling and harsh environments. Programmed in RBH’s proprietary 50‑bit format, it delivers secure, reliable performance with roughly 75 % of the read range of a standard proximity card, and its laser‑engraved serial number makes identification and management straightforward.
