S2C-SMT 3.50/04/90LF 2.3SN BK RL Weidmüller Interface GmbH & Co. KG Klingenbergstraße 26 D-32758 Detmold Germany www.weidmueller.com Accessories LED Light guides Effective: the link between LED and front panel. Floodlight indicators allow users to monitor the switching states without requiring a special design: optical plastic directs the light from standard LEDs around a bend into the connectors or through the front plate. The fibre-optic elements are simply clipped behind the relevant 90° bend male connectors (90° outlet direction). Versions with different incoming light beam heights achieve maximum light efficiency for LEDs with different designs or heights. The advantages compared to conventional solutions:

  • No additional LED circuit board required behind the front panel
  • No "long-legged" LEDs with separate mounting required
  • Bent fibre-optic cable line for maximum light efficiency
  • Uncomplicated front plate bore holes due to circular shape of outgoing light beam
  • Easy to maintain correct clearance and creepage distance
  • Can be partitioned for smaller pole numbers The result: simplified manufacturing process, reduced costs and simplified design General ordering data Type S2L/S2C 3.5 FLA 20/10 S… Version Order No. 1814590000 GTIN (EAN) 4032248302826 Qty. 50 ST PCB plug-in connector, Accessories, Flood-light display, Transparent, Number of poles: 10 Coding elements Only connects what is supposed to be connected: the right connection at the right place. Coding elements and locking devices clearly assign connecting elements during the manufacturing process and operation The coding elements and locking devices are inserted prior to assembly or during the cable assembly phase. The Weidmüller alternative: configure online using the variant configurator to precode prior to delivery. Incorrect assembly on the circuit board and incorrect plugging of connecting elements is no longer possible. The advantage: no troubleshooting during manufacture and no operational errors by the user.
