ProdataKey RDRMRS Ruggedized 125 kHz Mullion Reader

Control entry points that have limited wall space by placing a narrow mullion-format reader beside the door. The ruggedized housing suits reader locations where a standard-width wall reader would not fit cleanly. It reads 125 kHz proximity credentials and sends the credential read to an access-control panel through Wiegand wiring. Mullion mounting places the reader on the narrow vertical frame member adjacent to a controlled opening. RDRMRS addresses physical-access doors that use 125 kHz proximity cards or fobs and require a Wiegand reader connection. Its mullion profile is relevant at aluminum-framed glass doors, metal door frames, and other narrow mounting surfaces. A Wiegand interface supports integration into access-control architectures that accept reader data at the panel or controller. Select it when reader placement, credential frequency, and panel interface must all align. Installers can apply the reader at controlled doors where the access-control system expects Wiegand input rather than a network-connected reader. Ruggedized construction differentiates this option for exposed reader positions, while 125 kHz proximity technology keeps it focused on compatible proximity credentials. The reader does not alter the credential technology already deployed; it reads compatible 125 kHz credentials at the opening. Confirm mounting geometry, panel wiring, and credential compatibility for the door being equipped.
