PROID20BM-RS – ProID Series 13.56MHz Mifare RFID Card Reader (RS-485 Output, IP65 Waterproof, Matte Black)

Product Overview

The PROID20BM-RS is an enterprise-grade physical access control proximity reader engineered for high-security commercial, institutional, and industrial facilities. Operating at a radio frequency of 13.56 MHz, this reader is optimized for high-speed, encrypted credential transactions using standard Mifare (Classic / Desfire / Ultralight / Plus / S50 / S70) contactless smart cards, fobs, and mobile NFC tags. Designed with an advanced industrial RS-485 communication bus output, the PROID20BM-RS provides long-range serial connectivity to master access control panels—eliminating the strict 100-meter wiring distance limitation of legacy Wiegand systems while facilitating multi-drop reader bus topologies.

Engineered to perform reliably under extreme environmental conditions, the reader features an IP65 weatherproof ingress protection rating achieved through an internally encapsulated, silicone-potted solid-state electronic assembly encased in high-impact ABS+PC polymer housing. Designed in a sleek, architectural matte black finish, it integrates an intuitive tri-color LED status bar (Red/Green/Blue) along with an audible piezoelectric buzzer to provide distinct visual and acoustic feedback for access granted, access denied, and tamper conditions. With a read range of up to 5 cm (2 inches) and transaction response speeds under 300 ms, the PROID20BM-RS is an optimal credential verification terminal for door mullions, security turnstiles, and perimeter gates.

✅ Key Features

• 13.56MHz High-Frequency Smart Card Engine: Fast, secure reading of 13.56MHz Mifare contactless smart cards, keyfobs, and ISO14443A credentials.

• Long-Distance RS-485 Communication: High-speed serial RS-485 bus supports extended transmission distances up to 1,200 meters (4,000 ft) back to access control panels.
