Selection Notes

Unlike the integrated-antenna barrel and cuboid readers in this family, the RF250R ships without a built-in antenna and needs a separate ANT-series antenna wired to its M8, 4-pin antenna port, which lets the antenna sit apart from the reader electronics in a tight or hot mounting spot. Its lower IP65 rating (versus IP67 on the integrated-antenna readers) reflects the reader body only, since the antenna carries its own IP rating. Pick this split-antenna design over an integrated reader when the antenna needs to reach into a space the reader body cannot fit, and note the antenna itself is purchased separately.

Applications

Used where the antenna must be positioned away from the reader electronics, such as narrow slots, recessed tag positions, or high-heat zones where only the antenna can be mounted close to the tag.
