This is a contactless access control reader that utilizes an advanced RF receiver circuit design and an embedded microcontroller, combined with efficient decoding algorithms. It features high sensitivity, low current consumption, a single DC power supply, a low price, and high performance. Its fully sealed design, resistant to dust and moisture, allows users to install it outdoors and in other harsh environments, ensuring no mechanical wear and exceptional durability. Specifications: Operating Voltage: DC 12V; Current Consumption: 0–100 mA; Supported Cards: 125 kHz; Read Range: 0 mm–100 mm (depending on the card or environment); Reader Interval: <0.5 s; Format: Wiegand 26/Wiegand 34(User-configurable) Transmission Distance: WG26/34 ≥ 100 m Operating Temperature: -25°C to +75°C Dimensions: 41 mm x 80 mm x 12 mm Weight: Approximately 60 g Cable Length: 180 mm ± 5 mm Material: PVC & Resin Adhesive (IP65 waterproof rating) Status Indication: 2-LED (Blue indicates standby, Green indicates successful reading) Notes: 1. Turn off the power and do not operate while the device is live during installation or disassembly. 2. The reader must be mounted on a wooden, concrete, or brick wall, or placed on a table. There should be no large iron or steel objects within a radius of approximately 10 centimeters. 3. Different cards can affect the reader’s range. 4. If the distance between two readers is less than 0.3 meters, they will interfere with each other. In other words, the optimal distance between readers should be maintained at 0.3 meters or more. 5. If the card remains within the sensing area, the reader will not display any prompts and will not transmit data. 6. The Access Control Reader cannot store user data or information; we cannot add users via cards, passwords, or fingerprints. It is an unlocking device that only supports cards or passwords; you must rely on an access controller, time-and-attendance card machines, or multi-door controllers. Package Includes: 1 x Card Reader
