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 06.07.2025 04:01:03 MEZ Catalogue status / Drawings 8 **Data sheet** LLL **BL 3.50/12/90 SN OR BX** **Weidmüller Interface GmbH & Co.

About Novapart
Novapart is a B2B electronic component broker specialising in stock shortages and cost reduction. We source hard-to-find parts and identify compliant alternatives across a catalogue of 410,000+ components from 500+ manufacturers.
Learn more →Stock Shortage Specialist
When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.
Request a quote →Compliant Alternatives
We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
