Rated IP69K, these switches can withstand high-pressure and high-temperature washdowns. They detect the presence or absence of an object with a light beam moving at high speeds and produce PNP or NPN signal output. To determine the signal output of a switch you are replacing, use Testers for Proximity and Photoelectric Switches (not included).
IP67 and IP68 rated switches are protected from temporary submersion.
Direct sensing switches detect objects when light reflects back from the object. The transmitter and receiver are in the same housing, so they fit in confined spaces.
Receiver switches detect objects when an object breaks the light beam between the transmitter and receiver (both included). They have a longer sensing distance than direct-sensing and reflector switches.
Reflector switches detect an object when it passes between the switch and the reflector, interrupting the beam. They have a longer sensing distance than direct-sensing switches.
Switches with a plug connect to cables with a socket (sold separately), allowing you to quickly connect and disconnect the switch.
Color immune switches have the same sensing distance for dark and light colored objects.

Safety Laser Scanners
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.
