Long Description
The Chainway CM-5N is a high-performance 1-Port UHF RFID module built on the advanced Impinj E510 chip, offering outstanding performance in an ultra-compact form factor. Measuring only 31.0 Γ 19.0 Γ 3.1 mm and weighing just 3 g, the CM-5N is designed for seamless integration into a wide variety of handheld devices, card issuers, and all-in-one terminals. Despite its small size, it delivers powerful RFID reading and writing capabilities with superior sensitivity, low power consumption, and excellent stability.
Engineered with Impinj Gen2X support, the CM-5N provides enhanced tag communication reliability and high reading accuracy, making it ideal for short- to mid-range RFID applications such as container logistics, medical equipment tracking, and asset identification. The module features a low-power design and robust thermal management, ensuring efficient operation even under continuous use.
The CM-5N also demonstrates excellent resistance to electromagnetic interference (EMI) and provides stable, consistent performance across varied industrial and commercial environments. Its adjustable RF output power (5β30 dBm) and UART 3.3V TTL communication interface make it flexible and easy to integrate into existing systems.
Whether you are building portable RFID-enabled solutions or integrating RFID functions into compact electronic systems, the Chainway CM-5N offers a perfect balance of miniaturization, performance, and efficiency.
