<p>Safety light curtains are also known as safety light barriers or safety light screens. These optoelectronic devices are used to detect people present in the vicinity of moving machinery. Light curtains can be used as an alternative to mechanical barriers and other forms of traditional machine guarding. A set of light curtains contains a transmitter head and a receiver head. A transmitter generates an infra-red light between the two heads which acts as a detection zone. A movement detected within the detection zone initials the machine stopping procedure and automatically disconnect all hazardous machinery.</p><p>To reactivate the machinery, an operator has to press reset button that is positioned outside of the danger area. Some models are equipped with an auto-reset option that automatically starts machinery once the detection zone is free of obstacles. A response time of all light curtains is just a fraction of a second, it means that no other barrier type can compare to that.</p><p>Light curtains are great safety devices that are used to keep people safe around hazardous machinery which could cause them harm. They can help ensure user safety during routine operations like maintenance and repair.</p><h2><h2>Selecting the right light curtains</h2><p></h2>Maximum scanning distance and beam resolution are 2 important attributes that determine the right device for you. A distance between transmitter and receiver can be various from 0 to 20m and the choice depends on the type of machinery that is used in conjunction with the curtain.</p><p>Beam resolution determines detection capability, light curtains with 14 mm beam resolution are able to detect small body parts such as a finger, 20 mm ones are suitable for palm detection. Beam resolution of 20 mm and above are ideal for hand, head or full body detection. Typical beam resolution values are between 14 mm to even 70 mm.</p><h2><h2>Typical Applications</h2><p></h2>Light curtains are a way of safeguarding employees from dangerous machines. The design of the safety light curtain offers more flexibility and simplifies machine set up, maintenance and repair than other solid traditional guarding systems such as mechanical barriers and sliding gates. They can be found in various applications including:</p><ul><li>Packaging machines</li><li>Process machinery</li><li>Automated warehouses</li><li>Textile machinery</li><li>Electronic component assembly lines</li><li>Mechanical and hydraulic power presses</li></ul>

<p>Safety light curtains are optoelectronic safety devices used to prevent harm to people within the vicinity of moving parts on machines. Schmersal brings 60 years of safety experience to the table and have many light curtain combinations to choose from in their product line.</p><h2>How do Light Curtains work?</h2><p>Safety light curtains work via a sender pole transmitting the infrared light to a receiver pole. If an object passes through the light barrier and interrupts the transmission, it causes the machine to stop. This means there is appropriate safeguarding in place for the people around the hazard, thereby reducing susceptibility to injury and harm.</p><h3>The 440 Series – Setting the Standard</h3><p>Schmersal wants their products to be safe and stand the test of time, in the 440 Series they’ve constructed a durable, robust device that users can rely on. The outer tube is made from polycarbonate and has an impressive IP69K rating. This means that for industries where cleaning down equipment is necessary several times a day, the tightness of how the beams are constructed will withstand 80 bars of water pressure, has great resistance to alkalis, and can withstand hot steam.</p><p>Schmersal’s SLC 440 safety light curtain also features dirt detection on the sensors by measuring the intensity of the light being received. To prevent downtime and maintain productivity, a warning message will signal for action to be taken. Dirt detection is especially important given these devices are designed to situate in hygiene sensitive sectors, like the food and pharmaceuticals industries.</p><p>The protective tubes for the Schmersal safety light curtains are a mere 50mm thick but are breakproof even under extreme stress, meaning they can withstand large shocks and impact. With heavy machinery moving at pace and health and safety the highest priority for many businesses, RS stocks only the most trusted brands; Schmersal will not let you down.</p>

<p>Light curtains are an essential piece of safety kit in processing plants, factories, and along production lines. Also known as safety light barriers or safety light screens, a light curtain is formed of two parts – a transmitter and a receiver. The transmitter emits a field of infrared light which the receiver then picks up. However, if this field (known as a detection zone) is broken by an object it automatically sends a signal disconnecting any hazardous machinery in the area. Processes can only restart when the detection zone is clear once again.</p><h2>Light Curtain Sensor Advantages</h2><p><strong>Light guards for machinery have many advantages over traditional barriers,</strong> all of which increase the safe operation of your site. They are:</p><ul><li>Much harder to circumnavigate.</li><li>Able to respond in just a fraction of a second.</li><li>Fully automated.</li></ul><h2>Why Choose OMRON Light Barriers?</h2><p>OMRON are market leaders in the business of automation and are especially adept at providing solutions for large factories and plants that deal with manufacturing, food processing, pharmaceuticals and packing. They also take safety very seriously. With this in mind, they offer a wide selection of light curtain and safety sensors, suitable for all locations. With options covering everything from finger to whole body detection, they are an excellent choice for your automatic safety equipment.</p><h2>Safety Light Curtain Considerations</h2><p>One of the first things to consider is the location of the light curtain in terms of where it will be situated on your site. As part of their <a href="https://uk.rs-online.com/web/c/automation-control-gear/sensors/light-curtains/?applied-dimensions=4294965413,4290938367">F3S range</a>, OMRON can supply light curtains with a maximum scanning distance of 40m. These long-range sensors are ideal where visibility might be obstructed by objects, such as in warehouses or production lines creating large items. They can also be used to create crossing stations allowing people to move safely from one location to another.</p><p>Another thing to think about is how sensitive the light curtain needs to be in terms of whether it is reacting to small or large items. This is controlled by the beam resolution, with the smaller the number the more sensitive it is. For example, a 14mm beam resolution will detect small body parts such as fingers, while a larger resolution will be suitable for "whole body" applications. There are several options for fine detection within the <a href="https://uk.rs-online.com/web/c/automation-control-gear/sensors/light-curtains/?applied-dimensions=4294965413,4290820414">OMRON F3SG-R Advanced range</a> which also includes extra features such as simple set up, reduced resolution and pre-reset functions.</p><h2>OMRON Safety Scanners</h2><p>The OMRON range also includes laser scanners which can be used in much the same way as light curtains but with a 3D detection zone. The <a href="https://uk.rs-online.com/web/c/automation-control-gear/sensors/light-curtains/?applied-dimensions=4294965413,4290938344,4293456218">OMRON OS32C range</a> is compact, lightweight and offers low power consumption. They are particularly suited to intrusion detection for people coming onto your site; presence detection in machinery's hazardous areas; and collision avoidance for automated guided vehicles.</p>
