Our light curtains provide assurance to the employer and the machine operators that we can safely guard hazardous areas and the dangerous point of operation requirements of industrial machinery.  Applications such as power press guarding and controls, press brake guarding, robot guarding and automation guarding are just a few examples of our safety light curtain machine safeguarding capabilities.  Operator safety is our priority while effectively maintaining product quality which is backed by our long product warranties.  Properly designed and interfaced light curtains can have an extremely positive end result on production throughput.   We have also blended into our light curtain designs artificial intelligence (AI) for the light curtain system diagnostics for system faults that may arise over time.  This is a great time saver and enhances the subject machines overall equipment efficiency (OEE) for the front line supervisor.


The space-saving, compact profile of the Safety light curtain is ideal for smaller machines, yet robust enough to meet the demands of large power presses.
Positions first and last beam at the ends for continuous sensing included side-mount brackets allow no "dead" zone
14 mm or 25 mm resolution defined area heights from 270 mm to 1250 mm (10.6 to 71.2 inches)
Compact profile and multiple mounting options make Safety light curtain Safety Light Curtains a perfect fit for a wide range of machine safety applications
Available in nickel-plated housings for ESD-safe applications, clear anodized aluminum housing or "safety" yellow powder-coat housing
Safety light curtain Cascade models allow four systems—of any length and resolution—to be connected in series, forming a single safety device
Provides response times as fast as 5 milliseconds with detection ranges up to 20 m
Cascading adds only 1 ms to overall response time for each additional segment。

The safety light curtain is relied on to protect the safety of factory personnel all over the world. Yet, although the technology was developed almost 70 years ago, many applications may still not be making full use of its capabilities. I have tried to re-appraise what light curtains could be contributing to your machinery safety, factory control, and productivity with a breakdown of the functions and features that are currently available. The light curtain has become so ubiquitous, that it is all too easy to regard it as a simple on/off device - a fail-safe, fit-and-forget substitute for protective fencing. However, an expanding and versatile range of light curtains has evolved to perform multiple functions and they can contribute positively to productivity and integrate with factory local area networks to support better plant-wide automation.


Light curtain specifications
There really is no such thing as a straight like-for-like off the shelf ‘menu’ of safety light curtains since all manufacturers offer their own ranges including different sizes, shapes, and resolutions etc.    However, the starting point of any safety application is always the danger you want to guard against and the space that it is in.    Based on this, there are different attributes to consider regarding the physical properties of the light curtain.    Currently, the document EN ISO 13855 is the harmonized standard for positioning Safety light beam systems, and it can assist in determining which of these physical attributes to go for and in this section I have tried to explain the main specifications to consider.    However, there are also additional properties such as IP rating, current consumption, visible indications etc. that are not covered here.
