SP21 防水 IP68 航空圆形连接器 SP2116/P4 30A,500V 4 Pin 弯角电缆连接器 插头 公针 焊杯

Connection and Sealing

Threaded Coupling and Cable Seals. Choose the cable seal by the actual cable outer diameter: Seal I for 4.5–7 mm, Seal II for 7–12 mm, or Seal III for 5–9 mm. Align the keying and fully engage the thread before relying on the sealed connection.

IP68 Protection When Correctly Mated. The interface seal, threaded engagement and fitted cable-entry seal work together. IP68 protection depends on correct mating, assembly and use of compatible components.

Body Formats and Mating

Choose the Connector Format. The series includes SP2110 cable, SP2116 90-degree cable, SP2111C inline, SP2112 rear-nut panel, SP2113 two-hole flange and SP2115 front-nut panel formats. Each format is available with male or female contacts.

Match the Mating Pair. P denotes male contacts and S denotes female contacts. A valid pair requires opposite contact gender, the same contact count and the same insert pattern; shell appearance alone is not sufficient.

Termination and Ratings

Choose the Termination. Select Solder Cup for direct conductor soldering or Screw Terminal for mechanical wire clamping. The termination is part of the SKU, and ratings must be checked for that exact configuration.

Series Technical Specifications. Reference construction includes a threaded PC/Nylon 66 shell, PPS insert, gold-plated brass contacts, a −40°C to +85°C operating range and 500 mating cycles. Electrical ratings vary with the contact arrangement and termination.

Solder Cup Contact Ratings. Solder Cup layouts cover 2–15 contacts, 5–30 A and 400–500 V AC across the listed arrangements. The 5B, 6 and 6B layouts combine contact sizes, so current differs by contact group: 30/5 A, 25/5 A and 30/5 A respectively.

Screw Terminal Contact Ratings. Listed 2-, 3-, 4- and 5-contact Screw Terminal configurations are rated at 30 A and 500 V AC, with a reference conductor range of 0.75–4 mm². Verify the exact SKU before wiring.

Installation Dimensions

Cable Connector Dimensions. Review the SP2110, SP2116 and SP2111C dimensional drawings before allocating cable bend radius or enclosure space. Dimensions are shown in millimeters.

Panel Mounting Dimensions. Confirm the cutout, panel thickness and mounting method for SP2112, SP2113 or SP2115 before machining the panel.

Protective Cap Options. Tethered caps can help shield designated interfaces while disconnected. Cap compatibility and included parts are configuration-specific.

Select the Right SP21 Configuration

Before ordering, verify the body format, contact gender, contact arrangement, termination, electrical rating, cable seal, mounting dimensions and cap compatibility.

Selection note: Series information is a configuration guide. Verify the exact SKU, mating partner and included components before ordering.
