The SP21, SP17 and P13 serious are IP68 connectors, threaded coupling.
Compare to SP13/17 , SP21 has a larger shell and higher current range , it is a strong and tough connector designed for indoor/outdoor and underwater IP68 environments. It is ideal for any application which needs watertight connection conditions.
The connectors can be used for both cable to cable (in-line) and cable to panel-mount connections. Each side can be male or female contact, (Plug or socket versions), the IP68 Sealing caps are available for both cable connector and panel connector.
1) shell diameter (the panel hole cutout diameter): 21mm
2) number of contacts : 2 -12 gold plated contacts
3) rated current and V : 30A-5A , 500V-400V .
4) cable outer diameter acceptance: type I: 4.5-7mm , type II: 7-12mm
5) CE , ROHS approval
