General Description:

The HT2 DC20 S20 is a high performance transponder for bi-directional transmission in half duplex mode between read/write device and transponder.Data are stored in the transponder in a non-volatile memory (EEPROM). The transponder requires no internal power supply; it derives its power from the magnetic component of the RF carrier frequency generated by the reader. Data are transmitted by modulating this carrier.

Technical Features:

Identification transponder for use in contactless applications
Operating frequency 125 kHz
Data transmission and energy supply via RF link, no internal battery
Reading distance same as writing distance
Non-volatile memory of 256 bits (128 bit user data and 128 bit control data/secret memory) organized in 8 pages, 4 Bytes each
10 years non-volatile data retention
> 100 000 erase/write cycles
Selective read/write protection of memory content
Two coding schemes for read operation: Biphase and Manchester coding
Effective communication protocol with outstanding data integrity check
Mutual authentication function
Read/write mode allows:
- plain data transmission (password check)
- encrypted data transmission (crypto mode)
- In read/write mode multi-tag operation possible because of special HALT-function
Emulation of standard industrial read-only transponders:
- Public Mode A (MIRO and transponders from μEM (H400x))
- Public Mode B (according to ISO 11784 and ISO 11785 for animal identification)
- Public Mode C (PIT compatible mode)
