A flexible coding system has been developed by HARTING for its D-Sub miniature connector series which prevents cable connections from being connected to the wrong port in an I/O front panel incorporating several identical D-Sub miniature connectors.

The system offers 36 different variants which can be adapted to all D-Sub miniature series with housing type E. It can be installed by customers using an adapted HARTING service tool or delivered fully assembled. The new system is compatible with the standard D-Sub 9-pole, D-Sub high-density 15-pole and D-Sub mixed 2W2-2W2C-5W1 configurations.
