The 4‑Pin 25 mm M25 Green Heavy Duty Metal Aviation Plug & Socket Pair is a rugged, industrial‑grade circular connector set designed for reliable electrical connections in demanding environments — ideal for CNC machines, spindles, power tools, automation systems, and heavy‑duty equipment.

Specifications:

• Connector Type: Circular aviation‑style plug and socket pair (male + female)
• Series / Size Code: 25 mm (M25) threaded coupling
• Pin Count: 4 contacts
• Shell / Housing: Heavy‑duty metal construction with protective coating, typically in green finish for easier identification
• Contact Material: Metal alloy contacts designed for good conductivity and durability
• Current & Voltage Handling: Suitable for typical industrial power/signal applications (power and control supply for motors, spindles, or equipment)
• Connection Method: Threaded‑lock coupling — ensures secure, vibration‑resistant mating even under mechanical stress or movement
• Cable Entry: Designed for cable wiring; supports proper gauge wires for power or signal transmission

Features:

• Durable metal housing: Built to resist mechanical stress, impacts, and wear — ideal for workshop or industrial settings.
• Secure threaded coupling: Prevents accidental disconnection and ensures stable contact under vibration or movement — useful for machinery and rotating equipment.
• 4‑pin configuration: Provides flexibility to carry power and/or signal lines (e.g. ground, live, neutral, control) in a single connector.
• Compact circular design: Saves space and simplifies cable routing compared to bulky multi‑core cable runs.
• Versatile use: Suitable for spindle motors, CNC machines, industrial controllers, power tools, and other heavy‑duty equipment requiring reliable plug/socket power delivery.

Typical Use Cases:

• Wiring for air‑cooled spindles and CNC routers — safe, stable electrical connection that withstands vibration and rotation.
• Industrial machinery — connecting motors, drives, control units, or power supplies in workshop or factory environments.
• Power tools and heavy equipment — robust connector for power delivery where standard plugs may fail.
• Automation systems and robotics — secure signal/power line connection for sensors, actuators, and control modules in electrically noisy or vibration‑prone setups.
