Status: In production
Brand: Omron
Product: 3-in-1 RFID reader/writer with Modbus TCP
Communication standard: ISO/IEC 18000-3 (15693)
Host interface: Ethernet 10BASE-T/100BASE-TX, Modbus TCP
Longest communication range: 10.0–115.0 mm (V680S-HMD66-ETN + V680S-D2KF68/D8KF68)
Degree of protection: IP67
The V680S-HMD6x-ETN series is a 3-in-1 RFID reader/writer that combines antenna, amplifier and controller in a single compact housing. It conforms to ISO/IEC 18000-3 (15693) and connects to the host through its built-in Ethernet interface using Modbus TCP, so no network converter is required. Multiple reader/writers can be added to the same system through a switching hub. The series is offered in three sizes, 50 × 50 × 30 mm, 75 × 75 × 40 mm and 120 × 120 × 40 mm; it is powered from 24 V DC and draws 0.2 A max.
Settings, monitoring and read/write tests with tags are handled through the built-in web browser interface; no special software or special cables are needed. The reader/writer measures the communication signal and ambient noise to diagnose communication stability and reports the result on its LED indicators and to the host. With V680S-series 2 KB and 8 KB tags, the HMD66-ETN reaches a communication range of 10.0–115.0 mm on a non-metallic surface. The case is PBT resin, the degree of protection is IP67 and the operating temperature is −10 to 55 °C.
