RFID tags now have onboard sensor functionality

Turck extends its RFID system, BL ident, with new data carriers that combine memory space for RFID applications with integrated proximity switch and temperature sensor functionality.

The first 512 kB memory EEPROM tags were launched at the SPS/IPC/Drives show, with with an additional proximity switch and an integrated temperature sensor. Additional sensor combinations are planned for the near future.

The new sensor tags significantly extend an RFID system’s efficiency and allow various new applications that could not be solved efficiently with existing solutions.

For example, when attached to presses or conveyors, the new inductive sensor tags not only allow part identification but also position detection – without additional wiring. In this way, the new tags contribute to machine availability and process safety, because they allow detection of goods and security-relevant machine parts at the same time.

The data carrier with an integrated temperature sensor provides a new solution for monitoring the process temperature within autoclaves. The new tag helps users to verify that charges have passed through in accordance with the process.

They are specified for a temperature range of -40 to +105 °C, but short-time operation under ambient temperatures of up to +130 °C that might occur in autoclaves won’t harm the tags.

The sensor tags are available with or without an integrated power supply. They transmit and receive signals within the HF wave band (13.56 MHz).
