SIVA – RHINO™ HT 186 – Ultra-Mini On-Metal UHF RFID Hard Tag for Tools & Small Assets

The SIVA RHINO™ HT 186 is an ultra-compact, PCB-based UHF RFID hard tag designed for asset tracking in extremely space-constrained environments. With one of the smallest form factors in the RHINO™ portfolio, this tag is ideal for tools, medical equipment, hospital assets, IT components, and small industrial parts where traditional RFID tags cannot be accommodated.

Purpose-built for direct on-metal mounting, the RHINO™ HT 186 delivers stable and reliable RFID performance even when attached to metallic surfaces. Its high-temperature tolerance and IP68 protection make it suitable for harsh operating conditions involving heat exposure, moisture, vibration, and frequent handling.

Designed for mechanical screw mounting, the RHINO™ HT 186 ensures secure attachment in high-stress environments, making it a dependable solution for manufacturing, healthcare, maintenance operations, and industrial asset management.
