Access control reader Roger PR621-G Basic access control reader Grey Power consumption 50 mA

The RoGer PR621-G is a basic access control reader intended for efficient management of entry points. Designed with a compact rectangular housing (85 mm x 27 mm x 85 mm), the unit supports installation in small or constrained areas and is powered with a low consumption of 50 mA. PR621 readers are part of a family of economical access control devices that can operate as standalone units or be integrated into larger systems using their RS485 interface for programming and online communication.

Advantages

The PR621-G combines a compact form factor with low power draw, making it suitable for installations where space and energy efficiency matter. Its RS485 interface enables both local programming and networked operation in multi-reader systems. The reader supports access management for up to 1000 users when used within compatible access control architectures, and the housing and placement options simplify mounting at entrances, gates or internal doors.

Suitable for

• Standalone access points in offices and small businesses
• Integrated access control networks for medium-sized facilities
• Entry control for gates, internal doors, service rooms
• Installations requiring a low-power, compact reader

Key specifications

• Compact housing dimensions: 85 mm x 27 mm x 85 mm
• Power consumption: 50 mA
• Communication interface: RS485 for programming and online communication
• User capacity (system dependent): up to 1000 users when used in compatible systems
• Color/finish: Grey

How to use

Install the PR621-G reader at the desired entry point following standard mounting procedures for access control readers. Connect power and the RS485 communication lines to integrate the reader with a local controller or network interface. Configure reader parameters and enroll users either locally via serial/USB connection or remotely through a compatible network interface. After enrollment, present credentials to the reader to grant or deny access according to the configured permissions.

Recommendations

Place the reader at a stable mounting height and protect wiring runs from moisture and mechanical damage. Use RS485-compatible controllers and the recommended UT-4 interface when remote network management is required. For installations near metal doors or strong interference sources, verify read range and adjust mounting position to ensure reliable credential detection.
