RFID HARDWARE – Antennas – Mini-Guardrail Antenna

Specifically designed for demanding itemlevel deployments, Impinj’s Mini-Guardrail reader antenna operates effectively at read distances of 7.5 cm or less. This antenna is the ideal choice for access control, ticketing, document control, high-speed encoding stations, packaging lines, or any application requiring high reliability and a constrained read zone. Because of its optimized shortrange performance, the Mini-Guardrail antenna is virtually immune to the RFtransmission limiting effects of items such as liquids, powders, and metallic packaging.
