Shut off machinery on your roughest, dirtiest job sites the second someone or something gets too close. Shielded by a polycarbonate housing, these safety light curtains withstand impact better than standard models. Rated IP69, they’re sealed to keep out dust and high-pressure, high-temperature washdowns, so they'll stand up to mud, water, and heat on site. They're often used in construction zones and mining operations. When conditions are too harsh for inspections, use Bluetooth to send diagnostics to your phone. Simply connect to the app to monitor switching status, beam alignment, and other data from afar.

These curtains trigger when the light beams between the transmitter and receiver are interrupted. To selectively allow material to pass through the sensing field, you can program the system to allow one or more beams to be broken without shutting off your machine. To create a perimeter guard that bends around corners, add mirrors to reflect light beams at an angle.

For a complete switching system, combine a transmitter and receiver, which are sold together, with a safety relay (sold separately).

Note: These curtains cannot be used with a full-revolution clutch press or machine. Use only with machinery that can consistently and immediately stop anywhere in its cycle.

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 safety light curtains.

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 scanners 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.

Mount these scanners to a flat surface using holes on the back.

Create a perimeter around machinery by deflecting light beams from a single set of safety barrier switches. An alternative to buying multiple sets of switches, using these mirrors involves less wiring and setup time. Each mirror adds one side to your light beam barrier. For example, use two mirrors to create a three-sided barrier or three mirrors to create a four-sided barrier. However, each mirror slightly reduces maximum sensing distance for switches—use no more than three with a single set. The included brackets are adjustable, so you can angle the mirror exactly where you need it.

Spanning up to 230 ft.—roughly the length of a commercial airplane—these safety light curtains cut power to large machinery to prevent damage or injury. They trigger the instant a person or object crosses the light beams between the transmitter and receiver. To selectively allow material to pass through the sensing field, you can program the system to allow one or more beams to be broken without shutting off your machine. To create a perimeter guard that bends around corners, add mirrors to reflect light beams at an angle. Rated IP67, these curtains withstand wet conditions.

For a complete switching system, combine a transmitter and receiver, safety relay, and connectors (all sold separately).

Note: These curtains cannot be used with a full-revolution clutch press or machine. Use only with machinery that can consistently and immediately stop anywhere in its cycle.

All curtains require four fixed or four swivel brackets. Swivel brackets can be adjusted during and after installation for easy alignment.
