Near-field and compact antennas
SNFA
Pocket-size near-field antenna for reads up to 15 cm
Part numberID-ANTSNFA-FCC
An 85 x 35 x 22 mm near-field antenna weighing 35 g. It reads at up to 15 cm, so only the tag right in front of it answers: suited to verification and encoding stations.
Choose it when
You encode or verify one tag at a time, such as labels after printing, and neighbouring tags must stay quiet. Pocket-size, 85 x 35 x 22 mm, 35 g, reads up to 15 cm.
Need to reach 70 cm? The SFFA does. Counter reads up to 1 m? Choose the ANTNF1.

Questions we hear
Why such a short range?
On purpose. At up to 15 cm only the tag right in front answers, which helps with densely packed items and encoding.
What reader do I need?
One with an SMA antenna port, such as the DR-mini, DR-max or EM300. The antenna is IP54 with one SMA female connector. Input is limited to 4 W.
