WEIPU Circular Connectors for Industrial Robots & Automation

SHARE

 

 

Industrial robots and automated equipment rely on stable connections for power, signals, and data. In real factories, connectors often fail due to vibration, cable stress at moving joints, dust/oil exposure, and frequent maintenance cycles.

 

 

WEIPU circular connectors are widely used in robotics because they combine reliable transmission with rugged protection (IP44–IP68) and designs that withstand harsh industrial environments.

 

 

 

Why Connectors Matter in Robotics

 

Robots don’t just use a connector—they stress it continuously:

  • Joint movement pulls and twists cables

  • Vibration can loosen interfaces over time

  • Dust, oil mist, and washdown challenge sealing and corrosion resistance

  • High-cycle operation demands durable contacts and consistent conductivity

 

 

That’s why robot systems typically choose connectors based on retention method, sealing level, and whether they carry power, signal, or data.

 

 

 

 

Popular WEIPU Series for Robot Applications

 

 

 

 

 

WF Series — Durable Sealing for Sensor & Vision Connections

  • Key features: High sealing performance and strong durability.
  • Sensor connections: Machine vision / inspection systems
  • Why it fits robotics: Sensors and vision modules are sensitive to unstable signal and contamination—durable sealing improves reliability.

 

 

WY Series — Bayonet Quick Lock for Vibration-Heavy Robot I/O

  • Key features: Bayonet quick-lock design with excellent anti-vibration performance.
  • Where it’s used: Robot end-effector (tooling) connections, Joint I/O where vibration and frequent movement occur
  • Why it fits robotics: Sensors and vision modules are sensitive to unstable signal and contamination—durable sealing improves reliability.

 

 

SP Series — Cost-Effective IP68 Threaded Waterproof Connectors

  • Key features: High-value plastic shell, threaded coupling, and IP68 protection.

  • Where it’s used: Outdoor mobile robots, Automation control boxes/cabinets exposed to dust/water conditions
  • Why it fits robotics: A practical choice when you need high waterproof performance and stable threaded retention.

 

 

M12 Overmolded Series — Compact Sensor & Network Connectivity for Robotics

  • Key features: Standard M12 interface with overmolded cable, strong strain relief, and reliable sealing (ideal for high-cycle movement).
  • Where it’s used: Proximity sensors, encoders, IO modules, Robot wrist I/O, vision sensors, fieldbus/Ethernet links, Drag-chain/moving cable harness areas that need extra durability
  • Why it fits robotics: Overmolding reduces failure at the cable exit point and improves stability under bending, vibration, and frequent motion—great for sensor/data connections on automated equipment.

 

 

 

 

Key Functions & Specifications

 

Multiple Termination Options

WEIPU supports different wiring methods, including:

  • Solder
  • Screw
  • H-Screw
  • Crimp

 

This flexibility helps match production style, maintenance needs, and field installation requirements.

 

 

Hybrid Transmission (Power + Signal)

Some configurations support mixed layouts, enabling power and signal transmission within a single connector—useful when robot wiring space is limited.

Durable Contact Design

Contacts are often gold-plated to maintain stable conductivity and corrosion resistance, especially under high-cycle robot motion.

 

 

Data Interfaces for Robot Communication

For robot communications and device integration, waterproof connector solutions may include:

  • RJ45
  • USB 3.0
  • HDMI
  • Fiber (LC)

 

This supports applications where both environmental sealing and data performance are required.

 

 

 

 

FAQ

 

Q1: What IP level do WEIPU robot connectors support?

A: WEIPU connectors commonly cover IP44 to IP68, depending on series and application needs.

 

Q2: Which series is best for robot end-effector connections?

A: WEIPU WY series for end-effectors and vibration-heavy joint I/O due to bayonet quick locking and strong anti-vibration performance. Also, the SP series is a good option, as its IP68-sealed connection helps prevent ingress at the wrist I/O point.

 

Q3: Which series is used for outdoor robots or waterproof control boxes?

A: WEIPU SP series with IP68 protection and threaded coupling for outdoor mobile robots and automation control cabinets.
