Product details
Overview
RI-TRP-W9VS-30 from Texas Instruments is a batteryless, mount-on-metal LF RFID transponder operating at 134.2 kHz with HDX (Half Duplex) transmission, 80-bit read/write memory, and IP67-rated polypropylene housing. It delivers 309 ms typical programming time, supports 100,000 programming cycles, and is engineered for industrial asset tracking on metallic surfaces.
For engineers reviewing the RI-TRP-W9VS-30 datasheet, RI-TRP-W9VS-30 pinout, RI-TRP-W9VS-30 application, or RI-TRP-W9VS-30 equivalent, key selection criteria include its HDX modulation scheme, metal-mounting capability, 134.2 kHz FSK operation, 80-bit programmable memory with CRC, and compliance with IEC 68-2-27 mechanical shock testing.
Technical Context
This transponder uses HDX (Half Duplex) communication: the reader powers the device via magnetic coupling at 134.2 kHz, then pauses to allow the transponder to backscatter its response using FSK between 134.2 kHz and 123.2 kHz. No internal power source is required.
It implements a single 80-bit memory page with 64 user-programmable bits and a mandatory 16-bit CRC CCITT block check character. Memory is organized as one page only, with no sector or block addressing - all operations target the full 80-bit space.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Frequency | 134.2 kHz - defines resonant coupling frequency with reader antenna; determines magnetic field range and metal-interference resilience |
| Modulation | FSK (134.2 kHz / 123.2 kHz) - enables robust data recovery in noisy industrial environments by shifting between two discrete carrier frequencies |
| Memory Size | 80 bits total - structured as 64 user bits + 16-bit CRC CCITT; mandates CRC calculation for valid programming |
| Programming Cycles | 100,000 - specifies maximum write endurance before bit failure; critical for reusable asset tags in logistics |
| Reading Range | ≤ 120 cm - achievable under optimal conditions (regulatory-compliant reader, non-metallic mounting); reduced when mounted directly on metal without spacer |
| Operating Temp | –25°C to +70°C - validated for outdoor and factory-floor deployment; drops to 0°C minimum when used with Series 2000 readers |
| Protection Class | IP67 - ensures dust-tightness and immersion resistance up to 1 m for 30 min; suitable for washdown and harsh industrial cleaning |
Pinout & Package
This is a passive RFID transponder with no electrical pins or terminals. It operates via inductive coupling through an integrated coil antenna and requires no PCB-level interconnection. The device is housed in a sealed, black polypropylene enclosure measuring 102 mm × 36 mm × 16.5 mm and weighing 43 g.
Key Features
| Feature | Design Value |
|---|---|
| Mount-on-Metal Construction | Integrated ferrite layer and optimized coil geometry enable reliable operation when affixed directly to aluminum, iron, or steel surfaces without air gap |
| HDX Communication Protocol | Eliminates simultaneous transmit/receive conflict; allows deterministic timing control and improved noise immunity in dense-reader deployments |
| IP67 Sealing | Enables use in high-humidity, outdoor, or automated cleaning environments without protective enclosures or conformal coating |
| 100,000 Write Cycles | Supports long-term reuse in dynamic inventory systems where tag data is updated frequently across multiple service lifecycles |
| IEC 68-2-27 Shock Rating | Withstands 200 g half-sine shocks across three axes - validated for attachment to vehicles, machinery, and mobile assets subject to impact vibration |

Equivalent & Alternatives
The following parts are listed as comparable options for similar passive LF RFID transponder applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RI-TRP-W9VS-10 | Same core functionality and memory structure, but rated for 10% reading range (≤12 cm) and lacks IP67 certification | Intended for indoor, low-interference environments with short-range fixed readers | Select RI-TRP-W9VS-10 only if environmental sealing and extended range are unnecessary and cost sensitivity is primary |
| RI-TRP-W9VS-50 | Identical electrical and mechanical specs, but qualified for –40°C to +85°C operation and includes extended EMC validation per EN 61000-4-x | Required for arctic logistics, outdoor rail infrastructure, or medical sterilization-adjacent deployments | Choose RI-TRP-W9VS-50 when operating outside –25°C to +70°C or requiring certified immunity to conducted/radiated RF disturbances |
Compared with RI-TRP-W9VS-10 and RI-TRP-W9VS-50, the RI-TRP-W9VS-30 uniquely balances IP67 protection, 120 cm range, and standard industrial temperature range - making it the default choice for general-purpose metal-mounting in factories, warehouses, and vehicle fleets.

FAQ
What is the maximum read range of the RI-TRP-W9VS-30 in real-world metal-mounting scenarios?
The RI-TRP-W9VS-30 achieves ≤120 cm typical read range under ideal conditions - including regulatory-compliant readers, optimized antenna geometry, and non-metallic mounting. When mounted directly on metal, range reduces to ~30% of that value (≈36 cm), which remains sufficient for most gate or conveyor-based identification. Actual performance depends on reader power, antenna size, and local EMI.
Does the RI-TRP-W9VS-30 require a battery or external power connection?
No, the RI-TRP-W9VS-30 is fully passive and derives all operating energy from the reader's magnetic field at 134.2 kHz. It contains no battery, capacitor, or wired interface - enabling maintenance-free operation for the lifetime of the tag, provided mechanical integrity is preserved.
How is memory organized in the RI-TRP-W9VS-30, and what CRC standard does it use?
The RI-TRP-W9VS-30 provides a single 80-bit memory page, with 64 bits allocated for user data and 16 bits reserved for a mandatory CRC CCITT Block Check Character. TI-RFID LF readers automatically compute and verify this CRC; attempts to program invalid CRC values will fail.
Can the RI-TRP-W9VS-30 be mounted directly onto stainless steel or aluminum without performance loss?
Yes - the RI-TRP-W9VS-30 is explicitly designed as a mount-on-metal transponder. Its integrated ferrite layer and tuned coil compensate for eddy current losses in ferrous and non-ferrous metals, enabling reliable operation when screwed or riveted directly onto stainless steel, aluminum, or iron substrates without spacers or isolation layers.
What mechanical certifications apply to the RI-TRP-W9VS-30 housing?
The RI-TRP-W9VS-30 housing meets IP67 for dust and water ingress protection and is validated per IEC 68-2-27 (200 g half-sine shock, 3 ms, 6 shocks/axis) and IEC 68-2-6 (20 g vibration, 20–500 Hz). These ratings confirm suitability for rugged industrial deployment, including vehicle-mounted and washdown applications.
