Product details
Overview
RI-ACC-008B-30 from Texas Instruments is an antenna tuning module for 134.2 kHz HDX/FSK RFID systems, forming the resonant circuit with external antennas and enabling up to 120 m reader-to-antenna distance via twinax cable. It supports 8–80 µH antenna inductance range, operates from –25°C to +70°C, and delivers up to 380 Vpeak resonance voltage for industrial access control and vehicle identification.
For engineers reviewing the RI-ACC-008B-30 datasheet, RI-ACC-008B-30 pinout, RI-ACC-008B-30 application, or RI-ACC-008B-30 equivalent, key selection factors include its 8–80 µH tunable inductance range, 380 Vpeak resonance voltage capability, twinax-cable interface compatibility with RI-RFM-008B, and operation in harsh industrial environments per IEC 68-2-30.
Technical Context
The RI-ACC-008B-30 functions as a passive LC tuning board that interfaces between the RI-RFM-008B RF power module and external LF antennas. It does not contain active circuitry but provides precise impedance matching across 8–80 µH inductance values to sustain 134.2 kHz resonance under variable cable length and environmental loading.
Its design enables extension of the antenna location up to 120 meters from the reader module using symmetrical twinax cabling, maintaining signal integrity and peak resonance voltage up to 380 Vpeak while operating within –25°C to +70°C ambient temperature and <97% non-condensing humidity.

FAQ
What is the primary function of the RI-ACC-008B-30 in a TI RFID system?
The RI-ACC-008B-30 is a passive antenna tuning module that forms the resonant LC circuit with external 134.2 kHz antennas. It interfaces between the RI-RFM-008B RF power module and the antenna via twinax cable, enabling extended read range up to 120 meters. The RI-ACC-008B-30 itself contains no active components-it relies on precision capacitor networks and optimized PCB layout to match antenna inductance (8–80 µH) and sustain 380 Vpeak resonance voltage.
Does the RI-ACC-008B-30 require a power supply or control signals?
No, the RI-ACC-008B-30 is a fully passive tuning board with no internal power requirements or digital interfaces. It receives differential 134.2 kHz RF energy from the RI-RFM-008B module via twinax cable and delivers it to the antenna while maintaining resonance. All control, modulation, and decoding functions reside in the RI-RFM-008B and associated control modules (e.g., RI-CTL-MB2A), not in the RI-ACC-008B-30.
Which antennas are compatible with the RI-ACC-008B-30?
The RI-ACC-008B-30 supports TI-certified antennas with inductance values from 8 µH to 80 µH, including RI-ANT-G01E, RI-ANT-G02E, and RI-ANT-G04E gate antennas, as well as RI-ANT-S01C and RI-ANT-S02C stick antennas. Compatibility is determined solely by measured inductance-not physical form factor-and requires no firmware or hardware modification to the RI-ACC-008B-30.
Can the RI-ACC-008B-30 be used with non-TI RFID transponders?
The RI-ACC-008B-30 is designed exclusively for use with Texas Instruments 134.2 kHz HDX and FSK transponders. Its tuning network, resonance voltage profile, and interface timing align with TI's proprietary protocol stack and field strength requirements. Using it with non-TI transponders-even at 134.2 kHz-may result in unreliable read performance or failure to energize due to mismatched modulation depth and backscatter timing.
What is the maximum recommended cable length between RI-RFM-008B and RI-ACC-008B-30?
Texas Instruments specifies a maximum distance of 120 meters between the RI-RFM-008B and RI-ACC-008B-30 when using symmetrical shielded twinax cable meeting specified impedance and attenuation characteristics. Exceeding this length degrades RF power transfer efficiency and may reduce resonance voltage below the 380 Vpeak threshold needed for reliable transponder activation at range. Cable type, shielding quality, and termination must strictly follow TI's SCBS850 design guidelines.
