Threaded coupling
The coupling nut joins the matching connector bodies. Match the body family and contact arrangement before mating.
SP Waterproof Circular Connectors
Manufacturer
SP11, SP13, SP17, SP21 and SP29 circular connectors use threaded coupling for detachable cable and panel connections. Select the size, contact arrangement, cable seal and termination together. The catalogue lists IP68 protection; confirm the assembly and exposure conditions for your selected configuration.
Compare the five SP series
| Construction | Selection focus | Series reference |
|---|---|---|
| SP11 · Compact cable and panel | 2, 3, 4 or 5 contacts with solder termination. Cable seal range: 4–6.5 mm. Cable plug, inline socket, rear-nut panel socket and flange formats are listed. | SP1110 · SP1111 · SP1112 · SP1113 |
| SP13 · More contact arrangements | 2, 3, 4, 5, 6, 7 or 9 contacts. Type I cable seals cover 4–6.5 mm; Type II covers 5–8 mm. Select the current, working voltage and wire limit from the same contact row. | SP1310 · SP1311 · SP1312 · SP1313 |
| SP17 · Straight and angled formats | 2, 3, 4, 5, 7, 9 or 10 contacts. Straight plug and inline socket cable OD: 6–10 mm. Solder and crimp availability depends on the connector; solder ratings are not crimp ratings. | SP1710–SP1716 body families |
| SP21 · Cable and panel options | 2, 3, 4, 5, 7, 9 or 12 contacts. Cable seal options: 4.5–7 mm or 7–12 mm. Select the termination and conductor limit for the exact contact insert. | SP2110–SP2116 body families |
| SP29 · Larger cable entry | 2, 3, 4, 5, 7, 9 or 12 contacts. Straight plug and inline socket cable OD: 13–16 mm. Confirm the cable range for an angled version separately. | SP2910–SP2916 body families |
Inside the SP connection
Understand the coupling, cable seal and panel fixing before selecting a configuration.
Cable entry and seal
The rear clamping components and sealing ring must fit the actual cable jacket. Select the correct seal range and follow the model's assembly instructions.
Contacts and termination
The catalogue specifies gold-plated copper contacts. Solder, screw and crimp options depend on the series and insert; use configuration-specific wiring data.
Panel fixing and cap
Panel nuts, seals and protective caps depend on the body format. Confirm panel thickness, cutout and the specified protection condition rather than assuming a universal fit.
Match the contact insert, cable and body.
A series number or pin count alone does not define the complete connector specification.
Contacts & electrical ratings
Choose the required contact count, rated current and AC working voltage from the same configuration. One-minute dielectric withstand voltage is a test parameter, not the operating voltage.
Wire termination
SP11 and SP13 listings use solder termination. Larger families list configuration-dependent alternatives. Confirm solder, screw or crimp availability and conductor limits rather than transferring ratings between them.
Cable seal range
Measure the complete cable jacket. Choose the specified seal option for the selected body; conductor cross-section is a different measurement.
Mating & panel mounting
Match the body family and complementary P/S contacts. Check panel thickness, cutout shape and mounting holes using the exact socket drawing.

buying questions.
How are SP connectors different from LP connectors?
SP uses threaded coupling. LP uses a pushbutton snap-lock mechanism. Do not assume the series can mate with one another or share electrical ratings.
What do P and S mean?
P identifies pin contacts and S identifies socket contacts. These are electrical contact types, separate from whether the body is a cable plug, inline socket or panel socket. Specify both body style and contact type.
Can different SP sizes mate?
No cross-size compatibility is claimed. Match the series, listed mating body family, contact count and complementary contacts.
Does IP68 mean permanent underwater use?
No immersion depth or duration is established by the IP68 label alone. Confirm the selected assembly, cable seals, mating or cap condition and applicable test conditions before specifying the installation.
Are all SP connectors rated for the same current?
No. Current and working voltage vary with contact arrangement and termination. In particular, confirm the termination-specific current for SP21 and SP29 two- to five-contact configurations before ordering.
Can solder-contact data be used for crimp contacts?
Not automatically. A termination legend indicates possible options, not identical ratings or availability for every insert. Request the exact configuration's conductor and electrical data.
Where are the installation dimensions?
Each linked SP product page contains its body and panel-opening information. Use the selected socket's panel drawing, not the external connector diameter or mounting thread alone.
Does a V-0 housing classification certify the complete connector?
No. Housing material flammability and complete-product certification are different matters. Request applicable model-specific evidence when the project requires it.
What should I include in a quotation request?
Send the SP series, body designation, contact count, P/S contact type, termination, wire size, cable diameter and quantities for both mating sides. Include the exact model quantities, delivery destination and required documentation.
Can you review custom labels and packaging?
Send your part numbers, label artwork, pack quantities and shipment requirements. Feasibility, sample requirements, minimum quantities and lead time are confirmed for the requested models.
