Coding Keys

Poka Yoke connection



This coding element is used for the pin strips and plug connectors of the series 110, 120, 121 and 122. For each pole, the pin strips have a trapezoidal coding slot in which the coding element 120-K can be inserted. In the standard version the coding elements have a bright red colour, making them clearly visible in mated condition. Alternatively, they are also available in light grey and white. The white coding elements are made of a high temperature resistant material and are best suited for the application of SMD and THR suitable products. Delivery is in bulk in a bag. The red and light grey coding elements are not reflow solderable and for SMD & THR products they can only be used after the soldering process. 12 coding elements are related on a strip together.


Usable with: 110, 120, 121 and 122 series
