The 6005R mullion proximity reader is designed slim for areas with minimal surface space to mount a reader. Using RFID technology, the RCI 6005R reader interfaces with a wide range of electronic access control systems by complying with the Wiegand communication protocol. The reader operates at a frequency of 125kHz and has a proximity read range up to 5". The reader is intended for interior or exterior applications as all electronics are sealed in tamper and weather-resistant epoxy potting.
