The Telemecanique XUSL4E14F046NS1 is a safety light curtain, listed in the Light Curtain sub-category. It's built to guard hazard zones on machinery — presses, palletizers, robotic cells — where a person reaching into the danger area needs to be detected before the machine can cycle. The 14 mm resolution means it catches fingers, not just a torso, so it qualifies as finger-protection class per IEC 61496-1. That's the rating that decides fit: if your risk assessment calls for finger detection at the point of entry, this is the resolution tier you need.
Deployment Context
Mounts on the machine frame or guarding structure, not inside a panel — the emitter and receiver columns straddle the hazard zone. Cabling runs back to a safety relay or safety PLC. The 14 mm resolution is the key spec for fit: it determines the minimum object size the curtain detects. On a press brake or assembly station, that's the difference between a hand entering the pinch point and the machine stopping in time.
