Rockford Systems’ Protector Series features advanced safety functions combined with simplified installation and maintenance.

Rockford Systems introduced its Protector Series Light Curtains, which feature bi-color alignment indicators, simplified resolution settings, automatic diagnostics, remote fixed blanking, and can be interconnected in a cascading configuration. The series employs dual-scan technology that makes its photodiodes highly immune to EMI, RFI, ambient light, weld flash and strobe lights. The product’s design recesses the unit’s windows 5mm into the housing to prevent direct contact with the sensors. Emitters and receivers are both contained inside of 3mm-thick industrial grade aluminum housings with durable metal end-caps. They are rated IP65/IP67 to protect against liquid ingress or immersion. Units come in three resolutions – 14mm (finger detection), 23mm (hand detection) and 40mm (body detection) – for each light curtain length. All three resolutions have a range of up to 12 meters (39 feet).
