OMRON V680S-D2KF6x/D8KF6x — RFID Systems
Omron V680S-D2KF6x/D8KF6x: battery-less FRAM RFID tag, 2,000 or 8,192 bytes, IP68 and IPX9K, −20 to 85 °C, communication up to 115 mm.
Status: In production
Brand: Omron
Product: Battery-less FRAM RFID tag, 2 KB / 8 KB
Memory: FRAM, 2,000 bytes (D2KF) / 8,192 bytes (D8KF) user area
Write endurance: 1 trillion writes per block (85 °C or less)
Degree of protection: IP68, IPX9K
Longest communication range: 10.0–115.0 mm (D2KF68/D8KF68 + V680S-HMD66)
V680S-series RF tags are battery-less and use FRAM memory: D2KF models provide a 2,000-byte and D8KF models an 8,192-byte user area. The series comes in two sizes (40 × 40 × 5 mm and 86 × 54 × 10 mm) and two mounting types: flush mounting on a non-metallic surface, or flush mounting on a metallic surface for the M-suffix models. This gives eight combinations of communication range, mounting material and memory size. The tags are designed for V680S-series reader/writers; the 8 KB models require reader/writer version 2.00 or higher.
The tag body is PPS resin with good oil and chemical resistance; the degree of protection is IP68, and IPX9K is also provided for high-temperature, high-pressure water. Data is retained for 10 years after writing at 85 °C or less, and write endurance is 1 trillion writes per block. Operating temperature is −20 to 85 °C and storage temperature −40 to 125 °C. With a V680S-HMD66 on a non-metallic surface, the 86 × 54 mm tags reach 10.0–115.0 mm and the 40 × 40 mm tags 7.0–85.0 mm; the metal-mount models give 4.0–45.0 mm and 7.5–75.0 mm.
