Banner Engineering Extends S4B Safety Light Curtain Lineup with Larger Format Options
Industrial safety infrastructure continues to evolve as machine builders demand more flexible safeguarding components to protect operators in complex automated cells. Addressing these requirements, Banner Engineering has expanded its S4B safety light curtain portfolio, introducing four extended lengths for its high-resolution 14 mm variants to accommodate larger hazardous work envelopes without compromising detection accuracy.
Enhanced Versatility for Large-Scale Machine Guarding
Ensuring operator safety around fast-moving automated machinery requires reliable optoelectronic protection that can adapt to varying physical constraints. The S4B series, rated as a Type 4 safety device, now includes extended models measuring 1,350 mm, 1,500 mm, 1,650 mm, and 1,800 mm. These additions complement existing sizes ranging down to 300 mm, giving safety engineers the scalability needed to guard sprawling robotic cells, large automated assembly lines, and multi-axis material handling stations.
The curtains are engineered with integrated beam-strength and zone indicators, a design choice that drastically cuts down initial alignment, setup, and commissioning time on the shop floor. Depending on specific risk assessment requirements, the S4B family offers two primary resolution options: a 14 mm finger-detection resolution and a 30 mm hand-and-arm-detection resolution. This granularity allows system designers to balance safety compliance with operational efficiency, preventing nuisance trips while ensuring strict adherence to industrial safety standards.
Advanced Configuration and Cascading Topologies
Modern safety systems must also minimize wiring complexity and integration overhead. The S4B series incorporates flexible operational modes such as muting and fixed blanking, allowing specific light beams to be temporarily ignored or permanently disabled when routine material handling requires legitimate physical intrusion into the protected zone. For applications utilizing multiple light curtains on a single piece of equipment, the S4B supports a cascade configuration. Through integrated cordsets and gender-specific connections, multiple curtains link sequentially back to a single controller cable, streamlining panel wiring and simplifying downstream troubleshooting. Coupled with versatile mounting choices—including end-cap and center-mount brackets—these features provide machine builders with a robust safeguarding solution for demanding industrial environments.
