Dahua Technology ASR1200E-D RFID reader RS-485 Black

The DAHUA ASR1200E-D is a compact RFID reader designed for access control and tag identification in restricted installations. With dimensions of 96×43×17 mm and a black housing, it connects via an RS-485 interface to provide stable data exchange with controllers and security systems. The reader operates across a wide temperature range and is intended for use on doors, gates, or asset-tracking points where space is limited.

Advantages

The device offers a small form factor that fits constrained mounting locations while maintaining reliable RFID tag reading. RS-485 connectivity ensures robust communication over longer cable runs and easy integration with existing control systems. The specified operating temperature range allows use in varied indoor and sheltered outdoor environments.

Suitable for

• Door and gate access control panels
• Asset identification and tracking points in compact spaces
• Integration with RS-485 based security and building management systems

Key specifications

• Dimensions: 96 × 43 × 17 mm
• Interface: RS-485
• Power supply: 9–15 V DC, 100 mA
• Operating temperature: -30°C to +60°C
• Colour: Black

How to use

Mount the reader in a suitable location with adequate protection from direct exposure if installed outdoors. Connect power (9–15 V DC) and the RS-485 communication lines to the access control controller according to the controller’s wiring diagram. Position the reader so tags are presented within the manufacturer’s recommended read zone and verify communication and tag reading with the control system during commissioning.

Recommendations

For reliable long-term operation, use appropriate cable shielding for the RS-485 lines, ensure stable DC power within the specified range, and avoid mounting locations with prolonged direct exposure to severe weather despite the wide operating temperature range.
