Notice

1. Confirm the electric voltage (DC12V) and differentiate positive anode and cathode of power supply

2. When external Power is used, make sure sharing the power with Controller Box or using the same GND

3. When the distance between card reader and controller is more than 50m, please use Power Line with at least 1.5 square cm Dia, or using several parallel Network wires.

Overview of Model 204 Waterproof Reader

We manufacture the 204 as a water-resistant keypad RFID reader designed for low-cost, dependable door access in homes, small offices, and everyday commercial entry points. The housing is ABS, available in black or white, and the unit size is 115 × 76 × 18 mm. This slim wall-mount profile keeps installation clean. Its contactless design eliminates the socket wear risks common in Contact IC Cards readers, while providing a clear keypad interface and stable credential reading at the door.

Credential Flexibility and Access Modes

The reader is built to align with common proximity credential ecosystems. It operates at 125 kHz, with an optional 13.56 MHz configuration when a site standard is high frequency. For 125 kHz deployments, it supports TK4001 / EM4100 and compatible RFID Cards. When configured for 13.56 MHz, Mifare credentials are referenced as an option.

Access modes include password, RFID card, and a combination of both, allowing the same hardware to support simple day-to-day entry as well as stronger verification rules where required.

Integration and System Compatibility

For controller integration, the 204 supports Wiegand 26 and Wiegand 34 standard data output, and RS232 / RS485 are available as optional interfaces. Communication distance is specified as WG 26/34 < 100 m, RS232 < 10 m, and RS485 < 1200 m.

This helps installers plan controller placement and cable routing without pushing signals beyond defined limits. The standard Wiegand interface is also practically convenient for maintenance teams who may utilize RFID Duplicators for system testing and credential management. The reader includes built-in antenna design and provides built-in dual-color LED indication along with a buzzer, giving immediate feedback at the point of use.

Performance and Environmental Specifications

Operating power is specified as DC 9–16 V, and DC 12 V working voltage is referenced. Consumed current is specified at under 60 mA, while a 70 mA working current figure is also referenced at DC 12 V. Response speed is specified at less than 0.2 seconds, and reader interval is specified at under 0.5 seconds. This rapid RF verification supports smooth entry flow at frequently used doors, often proving more reliable than optical RFID QR Code Scanners which can be affected by ambient lighting.

Read range is specified at 3–8 cm, supporting controlled card presentation. Environmental capability is specified at -25°C to +75°C with 10%–90% ambient humidity, matching typical outdoor and semi-outdoor deployments. Installation guidance references separating the panel and motherboard for wall mounting with plastic plugs and screws, supporting straightforward field deployment. When you need a compact, water-resistant keypad reader with standard Wiegand output, optional serial interfaces, and flexible credential configuration, the 204 provides a practical solution for scalable door access control.
