September 4, 2012 - Schmersal announces SLC/SLG440 safety light curtains and grids. These optical safety sensors meet all North American approvals, including cULus, as well as European Norms EN/IECC 61496-1 and 61496-2 for optical devices. They are also suitable for applications of up to Ple per ISO13849-1 and SIL3 per IEC 62061. The SLC/SLG440 series offers fully integrated functions without the use of external programming devices or software which includes fully programmable blanking, integrated contactor monitoring (EDM), start/restart interlock, beam coding, and double acknowledgement reset. Programming of these features are made user-friendly with the use of only a button/enabling switch.
The 7-segment display offers indications which can be used to help with alignment, error diagnostics or simple operational mode statuses. OSSD indications are also displayed via a bright LED status cap. Because of the compact design (profile dimensions 28 x 33 mm) and rugged four sided structure, the SLC/SLG440 can be used in applications with limited space and withstand harsher environments.
