Protector Series Light Curtains

Feb. 9, 2022
Available in three common resolutions, Rockford Systems' Protector Series Light Curtains offer reliable detection and advanced safety functions.

Protector Series Light Curtains feature bi-color alignment indicators, simplified resolution settings, automatic diagnostics, remote fixed blanking, and can be interconnected in a cascading configuration. They are for safeguarding personnel near potentially dangerous industrial machinery.


Built for ease-of-use, they also provide for hassle-free installations that eliminate software, DIP switches, and expensive components. Brackets and connecting cables are all included as a kitted solution.


The bright bi-color alignment indicators run the length of the receiver window. In the event a sensor is not aligned properly or if the window requires cleaning, green lights will switch to red to instantly identify the problem area. Optional remote indicators can be purchased for long distance monitoring of light curtain status.


They employ dual-scan technology that makes its photodiodes highly immune to EMI, RFI, ambient light, weld flash, and strobe lights that may compromise sensor performance. Damage from impact is greatly reduced by a design that recesses the unit's windows 0.2 in. (5 mm) into the housing to prevent direct contact with the sensors. Emitters and receivers are both contained inside of 0.12 in. (3 mm) thick industrial grade aluminum housings with durable metal end-caps.


Protector Series Light Curtains are also ideal for industries subject to frequent washdowns or water spray, such as food, beverage, and pharmaceutical processing. They are rated IP65/IP67 so they offer total protection from low-pressure water jets and more substantial liquid ingress or immersion.
