The Zebra RFD90 Ultra-Rugged UHF RFID Sleds, which build on the RFD40 sleds, feature an ultra-rugged form factor with dual IP65 (spray)/67 (full submersion) sealing and six-foot / 1.8-meter drop specifications that can withstand virtually any environment, breaking the boundaries of traditional RFID use cases. All Zebra RFD90 Sled models include Bluetooth 5.3 for optimal device connectivity and industry-first integrated Wi-Fi 6 for device management over the air (OTA). The RFD9030 has a circular polarized antenna that can read RFID tags up to 22 feet away, while the RFD9090 uses a long-range, linear polarized, yagi-style antenna that can read RFID tags up to 75 feet away. The SE4750MR standard range scan engine or the SE4850 extended range scan engine are available on both the RFD9030 and RFD9090.
