CNC / Tooling / Molds
In CNC applications, RFID provides a solution to ensure the right tooling is in place before a process is allowed to begin. Molds have a finite life and RFID sensing provides a method to track which mold is nearing its end of life or which mold is brand new but producing rejected products at a 30% rate.
RFID Frequency options:
There are, with some exceptions, 3 main RFID frequencies to consider when deciding which to best implement according to the application specifics and requirements.
1. 125 KHz LF (low frequency) short-range passive RFID Tags.
LF can be out of the box metal friendly offering RFID Tags that can be mounted on or in metal without the need for additional backings or protection. It can be relied upon to not exceed an exacting range requirement thus ensuring the intended RFID Tag is read.
2. 13.56 MHz HF (high frequency) short-range passive RFID Tags.
While not as metal friendly without the need for additional backings, HF Tags generally slightly less expensive in basic forms, like labels. HF Tags can also be supplied as a label, important when disposable Tags are necessary. As a general rule, HF Tags cannot be subsurface mounted into metals or in metal intensive environments. HF can be relied upon to not exceed an exacting range requirement thus ensuring the intended RFID Tag is read.
3. 902-928 MHz UHF (ultrahigh frequency) long-range passive RFID Tags.
Certain UHF RFID Tags can be metal mountable and subsurface metal mounted. Those include Tags made of an FR4 material, ceramic material, or labels with a ferrous backing. UHF can provide read ranges measured in feet for smaller Tags and up to 10 meters with larger Tags. They can also be supplied as a label as the RFID industry’s most cost-effective disposable RFID Tag. An additional benefit is that UHF Tags can be read en masse, up to hundreds at a time, known in the RFID industry as anti-collision.
- LF Plastic Wedge - Coffin RFID Tag
Known as the RFID brick tag, plastic wedge and/or coffin tags due to its unique shape, the brick tag excels in applications requiring a small foot print as they can be embedded in space-restricted applications. Brick tags also offer great durability as they can withstand physical stress and are resistant to water, chemicals, acids, and temperature extremes. Brick tags can also be mounted on or in metal.
Brick Tag Applications
- Cable identification
- Tool or weapon inventory
- Surgical instrumentation tracking
- Medical equipment status and utilization
- UHF 915 MHz Ceramic RFID Tags
Ceramic UHF 915 MHz RFID tags offer metal mount ability as well as elevated temperature specifications. Ceramic RFID tags are also heat, water, and chemical resistant.
Ceramic RFID Tag Applications
- Electrical components for automotive industry such as board and parts management
- Surgical management and medical devices for medical industry
- Tool management for industrial and manufacturing
- UHF Model S4 Series RFID Readers
This Reader ports up to 4 addressable RFID Antennas with USB and Serial communications standard on all models, and further offer standard Ethernet, Profinet, Profibus, Ethernet/IP, Devicenet, Modbus TCP & RTU. Two lines of I/O are also standard. This Reader can also write to RFID Tags and has a range tuning feature.View Product
