ENGINEERING QUICK FACTS
CONNIXTECH industrial automation connectors support sealed sensor, power and signal interfaces in equipment and control systems. Current, voltage and IEC 60529 ingress ratings vary by model and must be checked against its approved specification.
Industrial Automation Connector Quick Facts
Definition: Industrial automation connectors are sealed electrical interfaces used between sensors, actuators, controllers, motors, Ethernet devices and mobile equipment. CONNIXTECH M-series connectors and custom cable assemblies are selected by circuit type, pinout, cable construction, shielding, movement, environment and maintenance requirements.
- Interface Families
- M8, M10, M12, M16 and M25
- Connection Types
- Sensor, power, Ethernet, servo and USB
- Cable Options
- PVC, PUR, shielded and high-flex assemblies
CONNIXTECH provides waterproof connectors and custom cable assemblies for industrial automation, sensors, actuators, control systems, AGVs and outdoor machinery. Connection solutions are selected around electrical performance, environmental exposure, movement, installation space and maintenance requirements.
Industrial Connector Selection Table
| Configuration | Interface / Contacts | Cable Construction | Typical Application | Engineering Check |
|---|---|---|---|---|
| M12 A-Code Sensor Cable | 5-pin sensor and actuator interface | PVC or PUR; shielding by signal requirement | Proximity sensors, valves, I/O and distributed control | Confirm pinout, voltage, current and cable outer diameter |
| M12 X-Code RJ45 Cable | 8-pin industrial Ethernet interface | Shielded twisted-pair data cable | Industrial Ethernet, cameras, control networks and mobile equipment | Confirm data protocol, shielding, bend radius and mating environment |
| M12 Multi-Branch Harness | 4-pin or 5-pin distribution layout | Defined trunk and branch lengths | Multiple sensors or actuators from one equipment connection | Check total circuit loading, voltage drop and branch labeling |
| M16 / M25 Power Connector | Power or hybrid contact layout | Conductor size selected by project load | Motors, controllers, charging and auxiliary equipment power | Confirm continuous current, temperature rise and installation space |
| Custom Industrial Cable Assembly | Ethernet, M12, servo, USB 3.0 or project-defined | PVC, PUR, shielded or high-flex cable | Control cabinets, robots, AGVs and production equipment | Provide drawing, pinout, motion profile and environmental requirements |
Connections for Sensors, Actuators and Control Equipment
Automation equipment uses compact connections for power, discrete signals, analog signals and communication. A reliable industrial cable assembly should maintain consistent contact while exposed to vibration, dust, oil, washdown, temperature changes and repeated cable movement.
M8, M10, M12 and M16 Cable Assemblies
Compact M-series interfaces are widely used around sensors, actuators and distributed control equipment. Available solution directions can include straight or right-angle outlets, cable-mounted and panel-mounted versions, power or signal contact arrangements and overmolded cable-entry structures.
Power, Signal and Hybrid Connections
- Sensor and actuator signal cables
- Distributed power cable assemblies
- Motor, controller and encoder harnesses
- Shielded and twisted-pair cable options
- Multi-branch equipment harnesses
- Panel receptacles and sealed in-line connectors
Cable Materials for Industrial Environments
The connector and cable must be considered as one system. PVC can suit many general installations, while PUR or other application-specific materials may be considered for movement, abrasion, oil exposure or demanding industrial conditions. Cable flexibility, bend radius, shielding, conductor size and outer diameter must match both the equipment and connector.
AGV and Mobile Robot Cable Assemblies
AGVs and mobile robots combine battery power, charging, motors, sensors and communication in a compact moving platform. Harness design can include branch routing, connector coding, strain relief, flexible cable sections, service loops and clear labels to simplify installation and maintenance.
Industrial Connector Selection Checklist
- Equipment function and installation location
- Voltage, current, contact count and signal type
- Required IP rating and washdown conditions
- Temperature, oil, chemicals, UV and abrasion exposure
- Static or moving cable installation
- Shielding, grounding and communication requirements
- Cable material, outside diameter and bend radius
- Connector orientation and available mounting space
Recommended Industrial Connector and Cable Configurations
- M12 Threaded Waterproof Connector for Automation — configurable circular interface for sensors and actuators.
- Metal M12 Threaded Connector — robust male/female interface for industrial automation cable assemblies.
- M25 2 Pin 40A Self-Locking Waterproof Connector — higher-current power connection for industrial and outdoor equipment.
- Custom Industrial Cable Assemblies — Ethernet, M12, servo, USB 3.0 and high-flex project capabilities.
Contact layouts, cable materials, electrical ratings and environmental validation must be confirmed for the selected configuration and application.
Industrial Automation Connector FAQ
What information is required to select an industrial automation connector?
Provide the equipment interface, pinout, voltage, continuous current, signal or communication type, cable length, shielding requirement, movement profile, target IP rating and environmental exposure. Mounting space, connector orientation and maintenance access should also be included.
When should PUR cable be selected instead of PVC?
PVC is a practical option for many static installations. PUR is commonly considered when the cable needs improved flexibility, abrasion resistance, oil resistance or repeated movement. The final jacket and bend-radius requirement should match the actual machine environment.
Can CONNIXTECH build custom splitter and robot cable harnesses?
Yes. Custom assemblies can include single-ended, double-ended and multi-branch layouts with project-defined connectors, pinouts, cable lengths, shielding, labels, overmolding and service loops. Drawings and prototype samples can be prepared for validation before production.
Custom Industrial Cable Harness Development
CONNIXTECH can evaluate single-ended, double-ended and multi-branch industrial cable assemblies. Customization can include connector type, cable length, wire gauge, pinout, wire colors, shielding, overmolding, labels, branch layout and prototype validation.

Engineering Q&A
How should I choose between IP67 and IP68?
Check the ingress rating for the exact mated or capped configuration and its IEC 60529 test conditions. IP67 and IP68 use different water exposure tests; confirm the required depth, duration, sealing and installation conditions on the approved drawing.
Does this connector support high-voltage shielding or HVIL?
Shielding and high-voltage interlock are not established for every connector configuration. Send the system voltage, shielding termination and HVIL pinout for engineering review before specifying either feature.
What are the sample and custom cable assembly lead times?
Sample and custom production timing is confirmed after review of the drawing, cable specification, quantity, tooling needs and validation plan. Share these requirements with CONNIXTECH for a project-specific schedule.
