Monitor a wide area around dangerous machinery. If a person or object gets too close, these scanners signal your relay or controller to either trigger a warning or shut down the machinery. For example, they can slow a robotic arm if someone comes within 20 ft., then stop it completely if they come within 10 ft. You can also set these scanners to respond only when they detect objects of a certain size. Since they continuously monitor 275°, they cover a much wider area than light beam safety barrier switches.

These scanners have a dedicated safety output for triggering emergency stops, and three inputs/outputs that you can configure. The safety output sends two duplicate signals at the same time—also called redundant signals—so even if one fails, the other will stop your equipment. Wire this output to safety relays or safety terminals on a controller. The inputs/outputs can be configured to set off warnings or adjust the scanner’s behavior. When used as outputs, they can send a signal to flash a light, sound an alarm, or slow a machine. When used as inputs, they can signal the scanner to ignore robot arms or other expected objects, while still scanning for people and unexpected objects.

Download free software onto a computer running Windows to set the monitoring distance, the size of the objects you want to detect, and the function of the inputs/outputs. You can also save up to six different configurations on the scanner itself.

Rated IP65, these switches are sealed to keep out dust and low-pressure jets of water. They’re UL and C-UL listed, CE marked, and TUV SUD certified, so they meet U.S. and international safety standards. They also meet EN, ISO, and IEC standards for performance and safety.

You’ll need a power/input/output cable to connect the scanner to your power supply, controller, or relay. Use an ethernet cord to connect the scanner to your computer for programming.

Mount these scanners to a flat surface using holes on the back. Add a mounting bracket to tilt the scanner toward the area you want to monitor. To shield the top of your scanner from falling objects and collisions, mount a protective bracket onto the mounting bracket.
