The 50mm 125kHz LF RFID Patrol Checkpoint Tag is a reusable proximity tag designed for security patrol routes, facility inspections, equipment checkpoints, and fixed asset verification. Its rigid 50mm diameter and 4.5mm thick ABS housing provides a durable physical marker for repeated indoor and semi-protected outdoor use. Multiple housing colors, including red, blue, green, and yellow, are available for visual classification of patrol zones, equipment groups, inspection points, or different project areas.
The tag uses an HT4168 125kHz LF RFID chip compatible with EM4100-type proximity reader systems. It provides a factory-programmed read-only unique ID for checkpoint verification and identification without rewritable user memory. This makes it suitable for patrol and inspection systems where each installed checkpoint needs a stable and permanent identification number.
Typical reading distance is approximately 2 to 10cm, depending on the reader coil, antenna tuning, tag orientation, mounting surface, and installation environment. The passive LF design requires no battery and is intended for repeated short-range identification. Custom services include multi-color housing, laser-engraved serial numbers, logo marking, and optional adhesive backing for fixed checkpoint installation.
