5. Chooseing tips:
If you have purchased fischer connector and know the original model, please tell us. We will directly offer you our corresponding one.
If you don’t know much about the connector, please make choose according the following factors:
- the use of the environment, indoors or outdoors, waterproof or not;
- the panel hole size, to select the appropriate plug and socket of right dimension;
- the current-voltage, number of contact and the realization of the function, to determine the contact(cores) ;
- select the appropriate clamp diameter and sheath;
- according to the actual needs of different angles of the keys, to determine the keying (the standard keys as N).
