Looking for a reliable, weatherproof, and high-speed proximity card reader that won’t break the bank? The KR-503E RFID Wiegand Reader could be the perfect solution for your access control needs.
Whether you’re managing a commercial building, hospital, school, or warehouse, security and convenience should go hand-in-hand. The KR-503E delivers just that—and more.
From rapid response times to dual-format Wiegand output and IP65-rated durability, here’s why the KR-503E stands out in today’s crowded market of RFID readers.
The KR-503E reads 125KHz proximity cards in ≤300ms, enabling almost instant access. This responsiveness eliminates delays and makes it ideal for high-traffic areas such as corporate lobbies, industrial sites, and university campuses.
With a read range of up to 10cm, users don’t need to touch or swipe the reader. This promotes a smooth, contactless experience and helps prevent wear-and-tear on both cards and the reader.
Unlike many basic RFID readers, the KR-503E supports both 26-bit and 34-bit Wiegand output formats. This dual support makes it compatible with most access control systems, whether new or legacy.
Rated IP65, the KR-503E is built to withstand harsh environments including rain, dust, and extreme temperatures. Its sturdy ABS+PC enclosure ensures reliable performance indoors and out.
With RS485 communication, dual input ports for LED and buzzer control, and clear wiring support, the KR-503E is plug-and-play ready. This makes installation and system integration fast and painless.
