Wilmall Connectors Manufacturer

Willmall supports procurement and engineering teams with Connectors supply covering material options, sealing for dust/water exposure, and defined dimensional ranges for cable entry selection.
  • Material options include brass nickel-plated, stainless steel, and PA nylon (as specified)
  • Dustproof and waterproof sealing to reduce ingress into cable entry points and equipment interfaces
  • Defined thread specification to match mating interfaces and installation requirements
  • Defined hole diameter to align with panel or enclosure entry machining
  • Defined clamping range to match cable outer diameter selection
  • Compatibility with M-series circular connectors for interface matching

What are Connectors used for in industrial electrical installations?

Connectors are used to create a repeatable electrical and mechanical interface between cables and equipment. Selection typically considers mating standard, mechanical retention, dimensional fit, and exposure conditions such as dust or water.

How do dustproof and waterproof features work in Connectors?

Dustproof and waterproof performance is achieved by limiting ingress paths at the interface between the cable, the connector body, and the equipment entry. Sealing elements and controlled compression are commonly used to reduce gaps where contaminants or moisture could enter.

Which parameters should be checked when selecting Connectors by thread and diameter?

Thread specification should match the mating interface, while hole diameter should match the panel or enclosure entry dimension. Clamping range should align with the cable outer diameter to achieve the intended mechanical hold and sealing compression.

How do material options such as brass nickel-plated, stainless steel, and PA nylon affect Connector selection?

Material choice is typically based on mechanical requirements and the installation environment. Brass nickel-plated and stainless steel are commonly chosen for metal-body applications, while PA nylon is used where non-metal housing requirements apply, subject to project specifications.

When is M-series compatibility important for Connectors?

M-series compatibility is required when the installation uses M-series circular connector interfaces. Matching the M-series standard supports correct mating geometry and mechanical fit in applications such as sensors, actuators, and industrial equipment wiring using M-series connectors.
