Overview

The SLC/SLG 440 is Schmersal's compact (28mm x 33mm cross-section), one-piece extruded-housing safety light curtain platform — no external controller or programming software required, with an integrated set-up tool and 7-segment status display. Rated Type 4 / Category 4 / PLe / SIL3 per IEC 61496-1 / EN ISO 13849-1, IP66/IP67. Supports fixed and floating object blanking (including a movable-edge blanking region), beam coding, EDM contactor-control monitoring, and a double-reset function for large partially-visible hazard areas. The AS-i variant integrates AS-Interface Safety-Slave communication directly into the curtain, eliminating separate safety-relay wiring. This finger (14mm, AS-Interface) SKU ships with 40 beams over a 410 mm protected height (the 14mm tier spans 170-1,770 mm).
