    Crane Safety Sensors

    Prevent collisions while moving heavy loads with overhead bridge crane systems. These sensors signal a crane to stop or slow when they detect that another crane or wall is too close. Mount the sensor on your crane and the included reflector on the obstacle you want to avoid. The sensor will bounce a light beam off the reflector to measure how far away it is—if it’s within the distance you’ve set, the sensor triggers. These sensors are also useful if you want to make sure a crane doesn’t move past a certain point. Turn the dials on the top to control the trigger distance and whether your crane stops or slows down. These sensors can communicate with any crane that uses a variable frequency drive (VFD), soft starters, or contactor controls.
    Mount the adhesive-backed reflector so the sensor's light beam hits its center. Built to avoid signal interference from other sensors, also known as crosstalk, these sensors can be used next to each other without a problem. They use polarized light, so they filter out unwanted light beams and their beam stays focused on their reflector.
    Rated IP67, these sensors seal out dust and water, making them suitable for both indoor and outdoor applications.

    Hazardous Location Proximity Sensor Safety Barriers

    Image of Specification. Front orientation. Contains Annotated, Border. Proximity Sensor Safety Barriers. Hazardous Location Proximity Sensor Safety Barriers.
    Safely transmit power to sensors in highly volatile areas. Commonly used in refineries, power plants, and wastewater-treatment facilities, these barriers use a NAMUR signal to reduce the current and voltage coming from your power supply—preventing sparks and ignition. While these barriers connect to sensors in hazardous locations, they must be installed in a separate nonhazardous area, along with the power supply. As associated apparatuses for IECEx and ATEX internationally certified sensors, they should be paired with items that have corresponding ratings. Mount to DIN rails inside control cabinets and electrical panels.
    Relay Output—Barriers with a relay output are slower than those with a transistor output, but they can handle higher AC and DC loads. Because of their moving parts, they wear out quicker than transistors. Use them to turn devices on and off, such as light bulbs and small motors.
    Transistor Output—Barriers with a transistor output are faster and last longer than those with a relay output. However, they can only be used to handle DC loads. Connect them to receiving devices, such as remote displays and programmable logic controllers (PLCs).

    Immediately cut power to machinery by breaking the light beam between two barriers. Light beams can travel up to 23 or 65 feet between the transmitter and receiver. They’re rated IP67, so they can be used in wet areas. For a complete switching system, combine a transmitter and receiver, safety relay, and connectors (all sold separately).
    These curtains can be configured for complex setups. 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 the Manufacturer User Manual, click on a part number and select Product Detail.
    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.

    Sensing Angle

    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.

    Safety Light Curtain Mirrors

    Image of ProductInUse. Front orientation. Contains Annotated. Safety Light Curtain Mirrors.
    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.

    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).
    For the Manufacturer User Manual, click on a part number and select Product Detail.
    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.

    Safety Light Curtains for Long Distances

    Image of ProductInUse. Front orientation. Contains Annotated. Safety Light Curtains. Safety Light Curtains for Long Distances.
    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).
    All curtains require four fixed or four swivel brackets. Swivel brackets can be adjusted during and after installation for easy alignment.
    For the Manufacturer User Manual, click on a part number and select Product Detail.
    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.
