V680-HAM91 RFID Read/Write Sensor (Amplifier-Integrated, Self-Contained), NPN Output
OMRON — V680 Series
Self-contained HF RFID "ID Flag" sensor that combines a read/write head and amplifier in one compact unit — unlike the V680-HAM42-DRT controller, it needs no external controller or antenna. It reads and writes 16 bits of ID data per cycle, making it suited to simple presence/ID-flag applications such as pallet, fixture or tray identification. This is the NPN-output version; a PNP-output version is sold as V680-HAM81.
Key Features
- Amplifier-integrated design — no separate controller required
- Reads/writes 16 bits of ID data per cycle
