125 kHz Proximity Card Reader Keypad, Mullion Mount Door Access Control RDRMRK

The ProdataKey RDRMRK is a rugged, vandal-resistant card reader and keypad access device designed for secure door access in indoor and outdoor environments. It combines proximity card (RFID) authentication with PIN entry for flexible two-factor security, eliminating the need for physical keys while giving authorized personnel fast, keyless entry to restricted areas.

This mullion-mount reader operates at 125 kHz and outputs Wiegand protocol, making it compatible with standard access control systems. Its compact rugged design handles both indoor and outdoor conditions, making it ideal for building entrances, server rooms, secure storage, and facility perimeters. The device accepts everyday proximity credentials alongside PIN numbers, allowing administrators to enforce multi-factor authentication policies.

Powered by 12V DC, the RDRMRK measures 6.3" high × 1.8" wide × 1.0" deep and is available in black or gray finishes. It replaces the earlier RDRMR model and carries a 5-year limited warranty.
