Refer to the perpin current ratings above for individual contact capabilities and select the pin configuration that matches your power and signal requirements. Typical applications Industrial automation and factory equipment where waterproof, vibrationresistant power and signal connections are required. Outdoor lighting, CCTV, and sensor installations that need sealed circular connectors for longterm weather exposure. Mobile and marine equipment, battery packs, and electric vehicles where mixed power and control wiring must be routed through a sealed bulkhead. Why choose this connector Flexible family of pin counts and contact sizes lets you match a single connector series to multiple system needs. Durable materials and goldplated contacts minimize contact degradation and maintain low resistance under repeated use. IP67 sealing combined with pushpull coupling supports fast servicing and reliable field use. Ordering and installation tips Confirm required pin count and whether solder or crimp termination is preferred. Crimp termination is available for 2 to 10 pin variants. Verify wire gauge and contact sizes against the perpin wiring table to ensure safe current carrying capacity. Refer to product images for panel cutout dimensions and detailed size parameters prior to installation.
