Control circuits with the tap of an RFID tag. Since each tag (sold separately) has a unique digital code, these switches aren’t just quicker to use than those with a traditional key—they’re also more secure. Use them to limit access to sensitive equipment, prevent accidental actuation, and also to keep tabs on access. Unlike standard switches, the RFID reader records data about every signal sent, so you can track exactly who operated these switches and when. They have enough memory to store and manage up to 500 tag codes, which you can rewrite and deactivate as needed.

All fit in a standard panel cutout. To set up these switches, connect them via ethernet cord (sold separately) to a computer, programmable logic controller (PLC), or another controller. No separate RFID writer required.

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.

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.

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.

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.
