Modern smart factories, robotics, and industrial IoT (IIoT) rely heavily on robust, standardized interconnect hardware. Choosing the correct metric circular connector size ensures signal integrity, mechanical rigidity, and environmental isolation under severe operating stresses.
Ultra-compact connectivity for space-constrained industrial equipment.
The undisputed global standard for factory automation and Ethernet control.
High-current and heavy-duty feedback connectivity for motors and drives.
| Series Size | Standard Thread | Available Pins | Rated Voltage / Current | Data Transmission | Ideal Applications |
|---|---|---|---|---|---|

| M23 | M23 x 1.0 | 6, 7, 9, 12, 16, 19 Pin | 150V-630V / 9A - 28A | Encoder / Power Hybrid | Servo Motor Power & Feedback, CNC Machine Centers |
To prevent mis-mating and mechanical damage, metric circular connectors utilize mechanical keying (coding). Understanding keying options is essential when specifying a circular connector A-code D-code X-code layout.
The most ubiquitous keying type used globally for basic DC power, IO-Link connectivity, and analog sensor communication.
Engineered specifically for Fast Ethernet transmission in harsh manufacturing shop floors.
High-speed industrial data backbone equipped with internal cross shielding (X-shielding) to eliminate crosstalk.
As industrial automation shifts from bulky junction boxes to decentralized field installations, specialized M12 power codings have emerged to replace traditional conduits:
Industrial environments present aggressive hazards including water washdowns, cutting fluids, continuous moisture, fine dust, and thermal expansion. Selecting the correct rating for an IP67 M12 or IP68 assembly prevents costly field outages.
Definition: Total protection against dust ingress (6) and protection against temporary water immersion up to 1 meter depth for 30 minutes (7).
Definition: Dust-tight sealing (6) engineered for continuous underwater submersion under customer-defined pressure/depth, plus high-pressure jet washdown resistance (IP69K).
Electromagnetic Interference (EMI) and Radio Frequency Interference (RFI) from variable frequency drives (VFDs), welding robots, and high-voltage power lines can corrupt digital signals.
Employs a continuous metallic shell grounding mechanism connected to aluminum foil and tinned copper braid cable shielding.
Lightweight, cost-effective overmolded assemblies without metallic EMI shielding layers.
Selecting the appropriate hardware mechanical style ensures ergonomic routing, strain relief, and space optimization across control cabinets and sensor housings.
Standard linear plug orientation. Ideal for open installations where straight cable withdrawal is accessible without tight radius bends.
Space-saving right-angle design. Essential for tight clearance machine frames, compact junction boxes, and dynamic robot arm joint routing.
Front-mount or rear-mount bulkhead receptacles with PG9, M16, or M12 jam nuts for enclosure feed-through connectivity.
Direct PCB dip-solder or Surface Mount (SMT) pin connectors for integrating waterproof ports directly onto custom controller boards.
| Cable Jacket Material | Flexibility Rate | Oil & Chemical Resistance | UV & Weathering | Recommended Applications |
|---|---|---|---|---|
| PVC (Polyvinyl Chloride) | Medium (Static) | Moderate | Good | Standard indoor machinery, low-cost assembly lines. |
| PUR (Polyurethane) | High (Flex Drag-Chain) | Excellent (Coolants, Cutting Oils) | Excellent | Robotic arms, machine tool drag chains, continuous motion systems. |
| TPE (Thermoplastic Elastomer) | Extra High (Flex) | Superior Resistance | Superior (UV Resistant) | Extreme temperature outdoor environments, agricultural machinery. |
