Sitron SULGA4-TU-23-500-2 Safety Light Curtain

Sitron SULGA4-TU-23-500-2 Safety Light Curtain is a pre-owned protective sensing device from Sitron Sensor GmbH that creates a beam-based guarded zone around industrial equipment, detects any interruption of its light beams, and communicates with safety control circuits to guarantee a controlled stop or safe state in line with IEC 61496—the standard that governs safety light curtain systems. The SULGA4-TU-23-500-2 designation places the unit within Sitron’s SULG A4 family, a line of safety light curtains described in Sitron’s operating literature for A4 configurations; this lineage is intended for reliable machine guarding in industrial environments where robust, modular safety solutions are required. As a pre-owned item, some marketplace listings note that mounting brackets may be included; before installation, verify the exact accessories, labeling, and condition with the seller to ensure proper integration with your safety circuit and compliance with your site’s safety requirements.
