KG Klingenbergstraße 26 D-32758 Detmold Germany www.weidmueller.com Accessories 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.
