1. S series connector brief introduction:
The original standard self-latching connectors with stepped inserts for alignment (of multipole version). A unipole coaxial connector is generally considered to be an element attached to a cable or mounted on an instrument as an electrical connection or separate component of the transmission line. Making it an ideal choice for Medical, Test & Measurement, Research, Communications, Broadcast Connector, Machines, Defense, Robotic, Aerospace, public sector, Information Systems, Motorsport, Miscellaneous applications. The modular insert configurations include a wide range of high-density multi-pole contacts.These high quality Spring Technology connectors cable assembly can be provided. it can cross Lemo variations and sizes.
2. S series connector description:
- security of the Push-Pull self-latching system
- multipole types 2 to 6 contacts
- solder contacts
- high packing density for space savings
- polarisation by stepped insert (half-moon) fitted with male and female contacts
- 360°screening for full EMC shielding.

5. Chooseing tips:
If you have purchased Lemo 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 G).
