Product Description

The M8 3-Pin Copper Wire Connector with Cable is a high-performance, compact circular connector engineered for reliable signal and power transmission in demanding industrial environments. This connector system features a robust M8 (8mm) threaded coupling interface with 3 pins, pre-assembled to a flexible and durable PVC or PUR cable. Constructed with a copper alloy core, gold-plated contacts, and high-quality engineering plastics, it ensures excellent electrical conductivity, corrosion resistance, and long-term mechanical durability. Designed to meet IP67 standards, it is completely protected against dust ingress and can withstand temporary immersion in water, making it an ideal, ready-to-deploy solution for connecting sensors, actuators, and small-scale devices in automation, manufacturing, and outdoor applications. Its compact size and rugged build provide a perfect balance between space efficiency and performance.

Product Features

3-Pin Configuration: Optimized for standard sensor and actuator connections, typically carrying power, signal, and ground.

IP67-Rated Protection: Guarantees complete dustproof performance and can be submerged in water up to 1 meter for 30 minutes, ensuring reliability in wet and dirty conditions.

Premium Copper Alloy Conductors: Provides superior electrical conductivity, minimizing voltage drop and energy loss for efficient power and signal integrity.

Gold-Plated Contacts: Enhances signal transmission quality and provides superior resistance to oxidation and corrosion, ensuring a stable connection over thousands of mating cycles.

Shielded Cable Option: Available with braided shielding to protect against Electromagnetic Interference (EMI) and Radio Frequency Interference (RFI), crucial for sensitive signal applications.

Rugged PVC or PUR Jacket: The cable features a flexible yet tough outer jacket. PVC offers general-purpose durability, while Polyurethane (PUR) provides enhanced resistance to oils, chemicals, and abrasion.

M8 Threaded Coupling Mechanism: Ensures a secure, vibration-proof connection that will not loosen accidentally in high-movement environments.

Color-Coded Housings: Available in standard industrial colors like black or gray for easy identification and matching.

Product Advantages

Enhanced Operational Reliability: The combination of IP67 sealing, vibration-resistant threading, and high-quality materials drastically reduces downtime and connection failures, leading to increased production efficiency and lower maintenance costs.

Superior Signal Fidelity: The use of pure copper wires and gold-plated contacts ensures that power and data signals are transmitted with minimal loss or interference. This is critical for the accurate operation of precision sensors and control systems.

Extended Service Life: Engineered to withstand harsh conditions including moisture, temperature variations, and mechanical stress, these connectors offer a significantly longer lifespan than Standard Connectors, providing a better return on investment.

Quick and Easy Installation: The pre-wired and molded design eliminates the need for on-site assembly of the connector head, saving valuable time during machine setup, wiring, and field repairs. The threaded coupling allows for tool-free mating and unmating.

Space-Efficient Design: The compact M8 form factor is ideal for modern, high-density control cabinets and compact machinery where space is at a premium, without compromising on performance.

Global Compliance: Manufactured to meet international safety and performance standards (such as CE, RoHS), ensuring they are suitable for global markets and applications.

Product Application Fields

The versatility and robustness of the M8 3-Pin Connector make it a preferred choice across numerous industries:

Factory Automation & Robotics: For connecting proximity sensors, photoelectric sensors, limit switches, and small actuators on production lines and robotic arms.

Process Control Systems: Widely used in PLC (Programmable Logic Controller) I/O connections, solenoid valves, and level sensors in chemical and processing plants.

Packaging Machinery: Ensures reliable connections for barcode readers, encoders, and control elements in high-speed packaging and labeling equipment.

Automotive Manufacturing: Applied in assembly line machinery, welding robots, and test equipment where resistance to oil and coolant is essential.

Outdoor LED Lighting Systems: Provides a waterproof connection for LED strips, garden lights, and architectural lighting fixtures.

Renewable Energy: Used in solar panel monitoring systems and wind turbine sensor arrays where environmental sealing is critical.

Telecommunications & Network Infrastructure: Connects devices in outdoor cabinets and base stations.

Product Frequently Asked Questions (FAQ)

Q1: What is the maximum current and voltage rating for this connector?
A1: Standard M8 3-pin connectors are typically rated for 2-4 Amps and 250 Volts, but this can vary based on the specific cable gauge. Please refer to the product's technical datasheet for precise specifications.

Q2: Can I order this connector with a custom cable length?
A2: Yes, we specialize in providing customized solutions. We can manufacture these connectors with your required cable length, jacket material (PVC or PUR), and even specific wire colors to match your application needs.

Q3: Is the IP67 rating valid even when the connector is mated?
A3: Yes, the IP67 rating applies to the fully assembled and mated connector system. The sealing is achieved through integrated O-rings and the precise design of the plug and socket interface.

Q4: What is the difference between PVC and PUR cable jackets?
A4: PVC (Polyvinyl Chloride) is a versatile, flexible, and cost-effective material with good general durability. PUR (Polyurethane) is more expensive but offers superior resistance to oil, chemicals, abrasion, and repeated flexing, making it ideal for harsh industrial environments.

Q5: What is the operating temperature range?
A5: The standard operating temperature range is typically from -25°C to +80°C, ensuring performance in most industrial and outdoor settings. Specialized variants may offer a wider range.

Q6: Are mating sockets available for purchase?
A6: Absolutely. We offer a complete range of panel-mount and cable-mount sockets designed to perfectly mate with this connector, ensuring a seamless and reliable connection system.
