Specifically designed for demanding item-level 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 short range performance, the Mini-Guardrail antenna is virtually immune to the RF transmission limiting effects of items such as liquids, powders, and metallic packaging. The Mini-Guardrail antenna’s short-range (0-7.5 centimeters) read zone makes it the ideal choice for a wide variety of item-level applications.
