CK-RA4L’s read range really comes down to a few practical things. You can tweak its output power up to 33dBm in small steps to balance distance and compliance, and its 4dBi circular antenna helps reach tags at different angles. The type of tag matters too—high-sensitivity UHF tags go farther. Metal, liquids, or other RF signals can cut the range, but the reader’s frequency hopping and carrier cancellation help keep it steady. For best results, set the right power, use good tags, and give the reader a clear line of sight without obstacles.

CK-RA4L is made tough for industrial use. Its IP67 ABS and aluminum housing keeps out dust and water and handles bumps and knocks. It works in extreme temps from -30°C to 85°C, whether in freezers or under the sun. Built-in surge and lightning protection shields it from power spikes, and the VSWR checks warn you if the antenna or cables have issues, keeping operations reliable in factories, warehouses, or outdoor tracking sites.

CK-RA4L is easy to integrate. It works with ISO 18000-6B/6C and GB/T29768-2013 tags, reads over 500 tags/sec, and sends data via Ethernet or RS232. Developers can use the SDK, APIs, and demo software to customize workflows, while remote firmware updates add new features. For large setups, TCP/IP networking lets you link multiple readers and centralize data on the cloud or on-prem servers.
