S4B Safety Light Curtains

Banner Engineering S4B Safety Light Curtains are two-piece optoelectronic safeguarding devices that come in a compact package for smaller production machines. These light curtains create a screen of synchronized, modulated infrared sensing beams that extend from end to end of the sensors, ensuring there is no "dead zone." The S4B safety light curtains feature a row of synchronized modulated infrared (invisible) light-emitting diodes, while receivers have a corresponding row of synchronized photodetectors. These curtains are highly immune to EMI, RFI, ambient light, weld flash, and strobe lights and offer a maximum sensing range of 0.1m to 12m, which decreases if corner mirrors or lens shields are used. The S4B safety light curtains feature zone and status indicators for diagnostics. These safety light curtains have 14mm and 30mm resolutions and are FMEA-tested to ensure control reliability. Typical applications include small assembly equipment, automated production equipment, robotic work cells, molding and power presses, and lean manufacturing systems.
