The Autonics engineered the SFL14-15 for high-precision safety applications. As a Safety Light Curtain (Standard Type), it uses a through-beam sensing method with an infrared LED (855nm) to detect opaque objects as small as Γ14 mm, ensuring accurate finger-level protection.
The protective height of 144 mm is supported by 15 optical axes with a 9 mm pitch, offering short mode detection from 0.2β5 m and long mode up to 10 m. The unit operates on a stable 24 VDC Β±20% supply, with selectable NPN or PNP OSSD safety outputs, auxiliary outputs, and lamp outputs for machine integration.
Built with an aluminum housing and polymethyl methacrylate front cover, the Autonics SFL14-15 achieves IP65, IP67, and IP69K protection ratings. It withstands temperatures from -30Β°C to 60Β°C and complies with global safety standards including ISO 13849-1 (PL e, Cat. 4) and IEC/EN 61496-1/-2.
