Technical FAQ

What should be confirmed before selecting LLT 4pin M19 Plastic Insulation IP68 Waterproof Electrical Wire Power Connector?

Confirm the sealing target, panel or cable interface, electrical load, and maintenance method together. LLT 4pin M19 Plastic Insulation IP68 Waterproof Electrical Wire Power Connector is currently configured around 2-18pin/2+4/2+5/3+5pin interface direction, so the enclosure fit and mating environment should be checked before final approval.

Which technical details matter most for this model?

Ingress protection in the current profile is listed as IP67/IP68. Rated current references include 20A. Review pin layout, termination method, cable OD, and lock structure together rather than choosing only by shell size or model name.

Can LLT support related cable assembly or customized integration for LLT 4pin M19 Plastic Insulation IP68 Waterproof Electrical Wire Power Connector?

Yes. LLT can discuss cable exit direction, overmolding, harness routing, and adjacent product alternatives when this model is part of a wider equipment interface or custom assembly project.
