A Comprehensive Introduction to M16 Connector for Industrial Use
If you're seeking a robust, compact, and versatile connector solution for industrial applications, the M16 connector for industrial use stands out. This comprehensive guide covers design, performance, variants, and real-world applications—paired with authoritative references—and shows how Connoder supports demanding automation projects with reliable circular-connector solutions.
1. What Is an M16 Circular Connector?
M16 refers to a metric-thread (M16 × 0.75) small circular connector (per IEC 61076-2-106 family). It offers multiple pin configurations (typically 2–24 poles), sturdy metal or engineering-plastic housings, and threaded (or bayonet) locking for secure mating in industrial environments.
2. Key Industrial Features & Standards
Environmental Protection (IP Ratings)
- Commonly available to IP67 when mated—dust-tight and protected against temporary immersion; suitable for outdoor or washdown scenarios.
- Premium variants achieve IP68/IP69K for prolonged immersion or high-pressure cleaning in harsh industrial conditions.

Mechanical & EMI Features
Metal housings with screw locking provide vibration resistance and excellent EMI/RFI shielding; plastic options are available for cost-sensitive, indoor applications.
Pin Arrangement Options
Typical configurations span from 2 to 24 poles, with solder or crimp contacts—supporting signal, low-power, or hybrid transmission in compact systems.
3. Performance & Specifications
Feature | Specification |

Thread & locking | M16 × 0.75, screw-lock; bayonet options available in some series |
IP rating | Up to IP67 standard; IP68/IP69K on enhanced models |
Housing / shielding | Nickel-plated brass or reinforced plastic; 360° EMI grounding options |
Temperature range | Typical –40 °C to +85 °C (series-dependent) |
4. Industrial Applications & Use Cases
- Automation & robotics: Compact I/O, robust under vibration.
- Instrumentation & sensors: Reliable signal/power in tight spaces.
- Harsh / outdoor environments: High IP protection for washdown and field deployments.
- Telecom & LED systems: Interfaces for 4G/5G modules, lighting, and packaging machinery.
5. Selecting the Right M16 Connector
- Define pin count & contact type for signal/power needs.
- Match the IP rating to the environment (IP67 vs IP68/IP69K).
- Choose housing & shielding based on EMI and corrosion exposure.
- Select mounting style (cable, panel, PCB; straight vs angled).
- Confirm vendor quality & support for lifecycle reliability.
