RI-STU-251B 2000 系列阅读器 S251B

The Texas Instruments’ low-frequency (LF) reader provides all the functionality required to communicate with Texas Instruments 134.2 kHz LF transponders which are available in a variety of form factors. The RI-STU-251B Reader/Writer is capable driving a variety of antennas with inductance ranges from 26.0 µH to 27.9 µH including TI standard antennas RI-ANT-G01E, RI-ANT-G02E, RI-ANT-G04E gate antennas as well as RI-ANT-S01C and RI-ANT-S02C stick antennas. The RI-STU-251B includes an automatic antenna resonance tuning feature which further reduces the need for maintenance and simplifies installation. It also supports both RS232 and RS422/485 interface standards.

The RI-STU-251B is well suited for usage in a broad range of applications including, but not limited to, access control, vehicle identification, container tracking, asset management and waste management applications
