Use these tags to efficiently scan, track, and manage inventory and other items in highly volatile areas. Intrinsically safe, they meet ATEX international certification to protect against explosion in environments containing flammable gases. Unlike bar codes, these tags store and share loads of information without needing a line of sight to scan. Their high frequency lets them transfer data at short distances—about 4 in. away from an RFID reader/writer. Capable of both read and write functions, their memory can be repeatedly rewritten and reused. Use them to provide feedback to automated tracking systems and devices, such as programmable logic controllers (PLCs). They’re also more durable than bar codes, which can wear out over time. Tags meet ISO and IEC standards for frequency ranges, and they’re IP67 rated, so they’ll still work if they get dusty or wet.

Scan and sort RFID-tagged inventory, track RFID-tagged items around your facility, and control building access. Unlike bar code scanners, these readers/writers can scan multiple tags simultaneously without direct line of sight. Plug in the included power supply, and connect them directly to your host system, such as a PC or programmable logic controller (PLC). As tagged items pass by, these readers/writers quickly read and transmit data to your system or write new information to the tags.

Configure your reader/writer settings and access tag data through a web browser interface. Reader/writers have color LEDs built in to indicate each successful scan. Choose a reader/writer that is compatible with the frequency of your RFID tags, cards, and labels (not included). Reader/writers meet ISO and IEC standards for frequency ranges.

High-frequency reader/writers are good for short-range scanning. They’re often used to sort or track items on a conveyor belt and to scan ID cards for facility access. Ultra-high-frequency reader/writers are good for long-range scanning and when scanning ranges may vary. Capable of reading up to 64 individual RFID tags in one scan, they’re often used to track inventory in bulk, such as pallets of tagged items.

Sensing distance for your reader/writers is reduced when tags are smaller, misaligned, not optimized for their mounting material, or scanned in hot or cold environments. The sensing distances in the table below represent typical factory conditions for a 26 × 100 mm tag optimized for its mounting material.

Scan RFID cards when prototyping systems for item tracking and conveyor sorting. These readers scan one card at a time without requiring a direct line of sight, so they'll work in areas where bar code scanners can't. An LED and a buzzer indicate each successful scan. Readers connect to your development board with an included Qwiic cord that snaps into place, saving you the effort of soldering. If your board doesn’t have a Qwiic connection, choose a cord with a machine-pin plug. The two included RFID cards, as well as additional cards, have unique IDs and cannot be rewritten.

Track the location of equipment, tools, and other material around your facility. These tags use Bluetooth to communicate with the free Milwaukee One-Key app on your smartphone—up to 300 ft. away. Update tag inventory and record information such as service reminders for each tag using the app or website. Made of polycarbonate, these tags withstand impact and weathering. Tie, screw, or glue onto material.

The convenient, modern alternative to mechanical safety switches. These RFID switches are easier to install, fit a wider range of access points, and can mount horizontally. Since they don't need a traditional key to actuate, they work even if the switch and actuator are slightly misaligned. Also known as interlock switches, they shut off power to equipment as soon as you open the barrier, which disconnects the RFID signal. These switches are often used with small machines. Find them anywhere from a CNC machine’s window to a packaging machine’s service panel. Mount the switch on the frame and the actuator on the barrier. Rated IP67 and IP69K, these switches are protected against temporary submersion and high-pressure, high-temperature washdowns.

The number of safety outputs, also known as output signal switching devices (OSSDs), tells you how many machines you can control. Each output has a pair of signals that shut down a single machine—if one signal fails, the other takes over as a failsafe.

Switches with a magnetic latch help prevent a barrier from opening by accident, such as from light bumps and low vibrations. The magnet keeps the actuator and switch from separating.

Micro M12 cords (sold separately) connect switches to your system’s circuits.

Block access to machinery while it's running. These safety switches cut power when their signal disconnects, shutting off equipment as you open machine guards. They link to a single actuator, so no other RFID tag or card can interfere. The unique RFID code means that once the power is cut, no one can bypass the switch and restart equipment while the guard is open.

These switches are often used with small machines where there’s no risk of the barrier closing on its own. Find them anywhere from a CNC machine’s window to a machine-operated saw’s service panel. Mount the switch on the frame and the actuator on the barrier. They're also known as interlock switches. Rated IP67 and IP69K, these switches are protected against temporary submersion and high-pressure, high-temperature washdowns.

Prevent accidental bumps or vibration from triggering these safety switches unnecessarily—a strong magnet maintains the RFID signal between the actuator and switch until it's intentionally opened. Also known as interlock switches, they automatically cut power when you open an access door, interrupting the signal, then restore power when the door is closed, and the switch and actuator meet. They're designed to mount on a frame and a door, gate, or window. Use them in many ways—from turning off a machine-operated saw when you open the protective window to powering down robotic arms when someone enters the partitioned area. The LED indicator shows that your switch is on and whether it’s actuated.

Switches with a unique RFID code are only compatible with their own actuator, so they’re difficult to tamper with.

IP67 rated switches protect against temporary submersion. IP69K rated switches protect against high-pressure, high-temperature washdowns.
