## Summary description

ZKTECO KR310 Black is a compact contactless card reader designed for access control systems. Physical dimensions are 42.8 mm (width) × 16.5 mm (depth) × 77.5 mm (height). It serves as a wall- or panel-mounted proximity reader for verifying credentials and integrating with access control panels in offices, residential buildings, or restricted areas.

## Long description

KR310 is an external Wiegand reader designed for ZKTeco standalone access control devices and control panels. It features a robust, weatherproof design suitable for outdoor installation and supports dual-frequency proximity reading with a typical range up to 10 cm. LED indicators show access granted or denied, and the unit can be wired to control a single door from both sides.
Advantages
The reader combines dual-frequency support (125 kHz and 13.56 MHz) with compatibility for common card formats, a compact form factor and IP65-rated protection against water and dust. Its simple wiring and clear LED status indicators make installation and daily operation straightforward.
Suitable for
Outdoor single-door access points
Standalone ZKTeco access control systems and control panels
Locations requiring both low-frequency and high-frequency card compatibility
When it may not be suitable
The KR310 is intended for proximity card access and basic Wiegand integrations; it is not a biometric reader and does not provide advanced credential management on its own. For installations needing long-range reading, integrated keypads, or multi-technology verification (beyond 125 kHz and 13.56 MHz), a different model may be more appropriate.
Key specifications
Frequency: Dual-frequency 125 kHz and 13.56 MHz
Read range: Up to 10 cm (typical for 125 kHz)
Protection rating: IP65 (waterproof and dust resistant)
Operating temperature: -10°C to +70°C
Form factor: Compact, surface-mounted reader (approx. 42.8 × 16.5 × 77.5 mm)

How to use
Mount the KR310 on a flat surface near the door at a recommended height for card presentation. Connect the reader to the access control panel using the Wiegand wiring and power supply according to the controller’s installation guide. Present a compatible card or tag within the read range; the LEDs will indicate whether access is granted or denied. Configure the controller to recognise card IDs and set door control logic as required.
What to consider before purchase
Ensure your access controller supports Wiegand input and the card formats you plan to use
Confirm required installation environment falls within the stated operating temperature range
Verify mounting space and dimensions match the reader’s compact size
Usage recommendations
For reliable outdoor operation, install the reader under some form of shelter if possible, use appropriate cable glands for weatherproofing, and test card compatibility with your controller before final installation.
