Product Overview
The DO-305 Wireless Keypad Reader is a 13.56MHz Mifare-based access control solution designed for secure entry management in commercial and industrial environments. This system consists of a wireless keypad and a receiver unit that communicate using 433MHz Rolling Code technology, ensuring that each transmission is unique and resistant to code grabbing or replay attacks. The receiver connects to any third-party Wiegand controller, making it suitable for system integrators upgrading existing access control infrastructure or deploying new secure entry points across multiple locations. Wholesale buyers and project contractors choose this reader for its reliable long-range wireless communication up to 30 meters and its compatibility with standard Wiegand 26-bit or 34-bit output formats. The keypad operates on three AAA batteries with ultra-low power consumption, while the receiver draws a stable DC 12V supply. The DO-305 is manufactured by do rfid reader manufacturer, a factory with two decades of production experience in RFID and access control hardware, supporting bulk orders, OEM customization, and large-scale project deployment.
Product Advantages
System integrators and security distributors require wireless access control readers that combine reliable encryption, flexible integration, and low maintenance. The DO-305 meets these requirements through 433MHz Rolling Code encryption, which prevents unauthorized replay attacks and provides secure credential transmission between the keypad and receiver. The Wiegand output supports both 26-bit and 34-bit formats, allowing direct connection to most third-party controllers without protocol conversion. The keypad operates on three AAA batteries with an idle current below 5µA, reducing battery replacement frequency and lowering total cost of ownership for facility managers overseeing large deployments. The communication range of up to 30 meters allows the keypad to be installed at a distance from the controller, simplifying wiring requirements and reducing installation labor. For wholesalers and project contractors, the DO-305 offers batch consistency, fast lead time, and compatibility with existing access control systems, making it a practical choice for industrial solutions requiring reliable long-term operation.

Industrial Applications
The DO-305 Wireless Keypad Reader is deployed across a range of commercial and industrial access control scenarios. System integrators use it for gated communities, parking barriers, warehouse entry points, office lobbies, and restricted facility zones where running cable between the keypad and controller is impractical. The wireless link reduces installation complexity and material costs, especially in retrofit projects. Distributors supply this reader to security companies managing multi-site deployments where centralized control and standardized hardware are critical. The 433MHz rolling code ensures that transmissions cannot be intercepted or replayed, addressing security concerns for high-value asset protection. The keypad is suitable for both indoor and sheltered outdoor use, with an operating temperature range that supports installations in varied environments. The optional wireless button provides an additional egress or request-to-exit function, further expanding its application flexibility. For factory and warehouse environments, the ABS housing provides adequate durability against physical contact and environmental exposure.
