Bring your requirements to an engineer.

Export cable, load, mounting conditions, and selected configurations to check mating parts and final drawings.

Current and voltage are verified per contact; for hybrid interfaces, match power and signal groups separately. Conductor cross section is pre-screened against the explicit catalog maximum; cable outer diameter must fall within the full sealing range. Series outline drawings do not replace the engineering drawing of the selected part number.

Specifications for waterproof connectors and aviation plugs apply per the specific model. Configurations that look similar may differ in ratings, pin positions, and mounting structure.Full technical notes。

Rated current and voltage.Rated current is stated per individual contact or designated contact group of the selected configuration; rated voltage is stated per the corresponding insulation structure. Simultaneous energization of multiple contacts, conductor cross section, ambient temperature, and heat dissipation conditions affect temperature rise and allowable current capacity. Selection results are for initial screening only; final selection must be verified against the datasheet and temperature-rise validation under actual operating conditions.

Hybrid power and signal configuration."3+2" and similar notations indicate the number of contacts in two contact groups. Current, voltage and wiring specifications must be verified separately; the rated currents of the two groups cannot be added together as an overall system rating. Different pin counts and contact-face layouts do not thereby imply intermateability; the viewing direction of the contact face, keying, and male/female contacts must all be confirmed together. Source and applicability Back to content
Wire diameter and seal fit.Enter conductor cross section per contact in mm²; cable outer diameter refers to the jacket outer diameter in mm. The two are not interchangeable. Conductor capacity can be pre-screened against the catalog maximum, but the cable outer diameter must fall within the sealing fit range—do not judge solely by whether the product maximum exceeds the cable diameter. AWG follows the corresponding wire gauge in the catalog. Source and applicability Back to content
Mounting form and face view.Front-mount panel, rear-mount panel, flange, and in-line mating describe the mounting structure; male and female contacts describe the contact form—the two are selected separately. Face views should indicate both the viewing direction and the locating datum; do not infer mating compatibility from left-right mirroring. Panel thickness, cutout, and locking conditions follow the drawing of the corresponding part number. Source and applicability Back to content
Image and demonstration notes.Product images are rendered from 3D data provided by the company; lighting, backgrounds, water droplets, light effects and particles illustrate the application environment and cannot replace test results. Protected structures are shown in desensitized appearance illustrations; none may be used as a basis for manufacturing, measurement, wiring or mating. For engineering documentation, apply to LLT per project. Source and applicability Back to content
