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. ## **General ordering data** |Type|BL SL 3.5 KO OR|Version| |---|---|---| |Order No.|1693430000|PCB plug-in connector, Accessories, Coding element, orange, Number| |GTIN (EAN)|4008190867447|of poles: 1| |Qty.|100 ST|| |Type|BL SL 3.5 KO SW|Version| |Order No.|1610100000|PCB plug-in connector, Accessories, Coding element, black, Number| |GTIN (EAN)|4008190187637|of poles: 1| |Qty.|100 ST|| Creation date 30.12.2025 11:06:15 MEZ Catalogue status / Drawings 8 **Data sheet** LLL **BL 3.50/15/270 SN OR BX** **Weidmüller Interface GmbH & Co.
