Light Beam Safety Barrier Switches
Immediately cut power to machinery by breaking the light beam between the two barriers. Light beams can travel up to 32 feet between the transmitter and receiver. For a complete system, combine a transmitter, receiver, safety relay, and connectors (sold separately). Switches will automatically produce PNP or NPN signal output based on the device they are connected to. 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.
Note: These switches 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.
Use safety relays when connecting these barrier switches to emergency stop switches.
Transmitter and receiver connecting cords allow you to connect multiple safety barrier switches in a row. They include one cord to connect two transmitters, and one cord to connect two receivers.
Optional adjustable brackets allow the transmitter and receiver to swivel from side-to-side, making it easier to align them during installation.
IP67 rated components are protected from temporary submersion.

Long Distance Light Beam Safety Barrier Switches
Transmit a beam of light up to 225 ft. from the transmitter to the receiver. They immediately cut power to machinery by breaking the light beam between the transmitter and receiver. A complete system requires a transmitter, receiver, transmitter connector, and receiver connector (sold separately). All are rated IP67 for protection from washdowns and temporary submersion. Note: Use only with machinery that can consistently and immediately stop anywhere in its cycle; do not use with a full-revolution clutched press or machine.
The transmitter and receiver have LED indicators that provide status and diagnostic information.

Wide-Angle Safety Barrier Switches
Scanning 275° side-to-side for people and objects, these switches (known as safety laser scanners) cover large areas and send signals to machinery to prevent accidents. Unlike other safety switches, which have a separate transmitter and receiver, these switches include the transmitter and receiver in a single unit. They trigger when light bounces off an object and back to the switch.
These switches respond to two types of areas: safety zones and warning zones. Safety zones act like traditional barrier switches—when a person or object enters the safety zone, they shut down machinery. When used with automatic guided vehicles (AGVs), the safety zone makes sure the vehicle has enough time to stop. Unlike other barrier switches, you can also add warning zones. Entering the warning zone triggers flashing lights, sirens, and other alarms, but doesn’t stop the machine. For AGVs, objects in the warning zone trigger reduced speed. Set up multiple warning zones to trigger escalating signals and precautions as the person or object gets closer to the machine. Switches with 10 or more zone settings let AGVs take more complex routes.
To program what areas to protect, what size objects they’ll detect, configure inputs and outputs, and view data, these switches come with their own software. This includes a muting feature, so you can program them to allow specific materials to pass through the scanning field without triggering a shut down. All have PNP output, so they communicate by sending a positive signal. They also have four LED status indicators and a digital display with push-button controls.
Rated IP65, these switches can be hosed down. They’re UL and C-UL listed, CE marked, and TUV certified, so they meet U.S. and international safety standards. They also meet EN, ISO, and IEC standards for performance and safety.
When choosing a switch, consider how much area you need to cover and how many machines you want to control. Independent switches monitor up to 275° of a single area. For more coverage, use master switches with up to three remote switches. This system can monitor a full circle around a large machine or a long space, such as the area along a conveyor. Connect remote switches to each other and to the master switch using remote switch cables. 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.
Master switches with encoder input monitor and adjust your AGV's speed without needing a separate PLC or other controller. Mount them directly onto your vehicle to make sure the safety zone is always large enough to prevent collisions.
Switches with 8- and 12-pole M12 sockets offer versatility as your application changes—use either the 8-pole or 12-pole connection without having to rewire. Switches with 8- and 17-pole M12 sockets require you to use the 17-pole connection; the 8-pole connection is optional if you want more inputs.
Safety relays receive safety output signals from switches and send them to machinery. They have self-monitoring circuitry, so they’ll keep working even if there’s a component or power failure. Any system that doesn’t have a safety control component will need a safety relay. They meet ISO and IEC standards for performance and safety. Rated IP20, they’re protected from solid objects greater than 12.5 mm, such as a finger. However, they’re not protected from water.
Power/input/output cables are required for independent and master switches. Data cables are required for connecting switches to your computer. This lets you program and monitor the switches, as well as read their measurement data.
Tilt mounting brackets up and down to make switches scan the correct area. Side-to-side brackets also move left and right. Add protective brackets to shield the tops of switches from falling objects and collisions. Use them with a mounting bracket.
