Wait a minute… Yea, I use nearly the same size light curtains throughout my plant. But with different functions. Are you saying that my 3rd shift mechanic can change ONE plug-in module, and I now have beam blanking capability, and I am up and running again in minutes? THAT’S CRAZY!
In a safe and healthy workplace, employees have a stake in the success of the program – safety and health are everyone’s responsibility. Actively encouraging employee improvement if you want your program to succeed.
Everyone working together, has enabled Rockwell Automation to proudly introduce the Allen-Bradley GuardShield 450L-B and 450L-E Safety Light Curtain system. The rise of robots and the need for a safe work environment, has created an increased demand for safety light curtains.
The 450L GuardShield is a flexible, cost-effective solution that enhances safety while improving productivity through innovative “transceiver” technology. The usual legacy light curtain systems are based on a two-stick (transmitter & receiver) concept. The 450L manages to offer the same functionality with two identical sticks. This feature makes logistics much easier and helps to minimize stocking costs.
The functionality of a 450L transceiver stick is determined by a plug-in module that is inserted into the stick housing. Depending on the plug-in functionality that the application requires (e.g. start mode, muting, blanking EDM or cascading), choosing the proper plug-in allows you to select and pay for only the functions you need. Although there is a universal plug-in that contains all functions, and its programming is achieved via dip switches or free software. This allows to further reduce parts stocking.
The 450L-B offers on/off functionality and reset modes making it the most cost-effective solutions for most applications. While the 450L-E offers an integrated laser alignment as standard for ease of installation. The 450L-E also has other plug-ins for more sophisticated applications and offers blanking, muting (for 2 or 4 sensors), EDM and cascading. Both light curtain series offer 14mm resolution for finger protection, and 30mm resolution for hand protection.
The 450L Safety Light Curtains has a compact design of 30mm x 30mm and has an IP65 enclosure rating. They are TUV certified PLe, Type 4 and Silcl3 per EN ISO 13849-1 and IEC 62061.
Scanning ranges vary depending on the 450L-B and 450L-E beam resolution. The 450L-B range is from .5m to 6.5m. And the 450L-E .5m to 16.2m. Protective height on both series range from 150mm to 1950mm.
