Function	Benefits
IP68 full‑sealed waterproof & dust‑proof structure	Tolerates temporary immersion and heavy dust; prevents short‑circuit caused by water ingress for stable continuous operation in harsh wet environments.
4‑pin design for combined power & signal transmission	Delivers power and signal via one single connector; reduces joint quantity and simplifies whole‑system wiring.
M25 circular bayonet locking, male‑female quick plug‑and‑play	Tool‑free fast installation & disassembly; saves labor time for on‑site assembly and routine maintenance.
High‑strength PA66 housing with gold‑plated brass contacts	Excellent vibration & corrosion resistance; keeps stable contact without signal loss or power attenuation.
Support panel‑mount and cable‑to‑cable connection	Fits two mainstream installation modes: device chassis outlet and cable interconnection, compatible with diverse equipment structures.

IP68 M25 4 Pin Waterproof Connector Application Scenarios

mainly use to power cable connection: led lighting, industrial, solar panel, etc
generally use to control box of power, such as feeding control system

Application Scenarios	Business Values for Customers
Outdoor LED lights, street lights & garden lighting projects	Reliable performance under rain and underground humidity; lower fixture failure rate, less maintenance & rework for stable project delivery.
Marine near‑shore equipment, fountain & water‑feature devices	Reliable IP68 protection against splashing and immersion; guarantees long‑term underwater operation and reduces costly equipment downtime.
Industrial automation machinery	Stable power & signal transmission under vibration, oil and dust; improves overall reliability of production‑line equipment.
Energy storage & outdoor power supply units	Safe connection in rainy & humid outdoor environments; avoids risks of electric leakage and short circuits, enhances end‑product safety level.
Construction machinery & off‑road on‑board devices	Stable performance under wide temperature swings, vibration and rain; extends whole‑equipment service life and boosts end‑product market competitiveness.

Customer Pain Points	Product Solutions
Ordinary IP67 connectors fail after heavy rain or water immersion, leading to device burnout	Upgraded IP68 rating with multi‑layer sealing gaskets, effectively avoids water‑damage failures under immersion conditions.
Separate connectors for power and signal cause messy wiring and high wiring error rate	Integrated 4‑pin carries both power and signal, streamlines harness layout and lowers on‑site wiring mistakes.
Vibration in industrial sites loosens connectors and causes intermittent connection	Bayonet locking circular structure, anti‑vibration & anti‑loosening for reliable connection under mechanical shock.
Metal contacts oxidize under salt‑spray & humid outdoor conditions, triggering poor contact	Gold‑plated brass contacts resist salt spray & oxidation, extend service life and cut after‑sales replacement costs.
Complicated installation requiring professional tools on construction sites	Tool‑free plug‑and‑play male‑female mating, enables fast field assembly by ordinary workers.

Male & Female M25‑4pin Circular Cable Connector Features

panel mount: the male connector is front panel mount type
female is inline assembly type.

Key Specifications	Competitive Advantages
IP68 protection rating	Withstands immersion at 1 m depth for 24hours, outperforms IP67 for outdoor high‑demand wet‑condition applications. (not underwater long time)
4‑pin, rated current up to 15 A, rated voltage 500 V	Handles high‑power power supply while supporting signal transmission, simplifies component selection.
Contact resistance ≤5 mΩ, gold plating thickness 0.8 μm	Low contact resistance for stable signal transmission; anti‑oxidation, ≥3000 mating cycles service life.
PA66 housing, IK09 impact resistance	Resists mechanical impact, anti‑breakage for rough construction‑site and outdoor working conditions.
Operating temperature: ‑40 ℃ ~ +105 ℃	Reliable performance under extreme cold and high‑temperature sunlight, suitable for global outdoor projects.
Standard M25 circular dimension	Industry‑standard cut‑out size, direct replacement for competing M25 connectors without modifying equipment molds.
