Phoenix SACC-EC Series Industrial Circular Connectors Complete Selection Guide

I. Series Overview: Industrial-Grade Circular Connectors for Standardized Assembly & Signal/Power Transmission

The Phoenix SACC-EC series is a specialized portfolio of industrial-grade pre-assembled circular connectors, designed for reliable signal and low-to-medium power transmission in factory automation, control cabinet wiring and field device interconnection scenarios. This series covers two core interface categories: standard M16 interface connectors and compact M12 interface connectors, with core configurations including 2/4/5/8-core universal pins (CON), flexible cable length options (0.5m–10m) and professional functional suffixes (SCO for standardized assembly, VA for voltage compliance, 910/920/931X for custom project specifications).

All variants adopt industrial-grade high-strength thermoplastic housings and gold-plated contact pins, supporting IP67 ingress protection (when mated), wide temperature tolerance (-40°C to +85°C) and EMC anti-interference performance. The series is perfectly compatible with Phoenix SCO standardized assembly systems and mainstream industrial control equipment, realizing efficient, stable connection in harsh industrial environments.

Core Advantages

1. Dual Interface & Multi-Core Coverage: Supports M16 and M12 mainstream industrial interfaces, with core counts ranging from 2 to 8, covering basic signal transmission to high-density multi-channel data interaction scenarios.
2. Professional Suffix Function Matching: SCO suffix enables batch standardized assembly for new project deployment; VA suffix meets regional voltage safety regulations; 910/920/931X custom suffixes adapt to project-specific interface requirements.
3. Flexible Cable Length Configuration: Cable lengths range from 0.5m to 10m, matching short-distance cabinet internal wiring and long-distance field device connection needs.
4. Industrial-Grade Reliability: Reinforced housing with vibration and corrosion resistance; gold-plated contacts ensure low contact resistance and stable transmission in high-noise environments.
5. Standardized Assembly Compatibility: SCO suffix models are compatible with Phoenix SCO assembly systems, reducing on-site installation time by 30% for batch projects.

SACC-EC-[Interface/Structure Type]-[Core Count+CON]-[Installation Interface/Cable Gland]-[Cable Length]-[Suffix]

Key Component & Suffix Interpretation (Critical for Selection)

• SACC-EC: Phoenix industrial circular connector series identifier
• Interface/Structure Type Code:
  • MS/FS: Basic male/female connector structure (MS=male, FS=female, for general scenarios)
  • MSB/FSB: Enhanced male/female connector structure (reinforced contact, for vibration-prone environments)
  • MSD/FSD: Dedicated male/female connector structure (optimized for high-density signal transmission)
  • M12MS/M12FS: M12 interface male/female connector (compact design for field sensors/actuators)
• Core Count & CON:
  • 2/4/5/8: Number of signal/power transmission cores (match channel requirements of the system)
  • CON: Universal core type (supports mixed signal and power transmission, most versatile)
• Installation Interface & Cable Length:
  • M16: Standard M16 installation interface (for control cabinet panel mounting)
  • PG9: PG9 cable gland (for 5–9mm diameter cables, provides dust/waterproof protection for field wiring)
  • 0.5m–10m: Cable length (select according to actual wiring distance between devices)
• Critical Functional Suffixes:
  • SCO: Standardized assembly suffix (compatible with Phoenix SCO assembly system, for batch installation)
  • VA: Voltage compliance suffix (meets regional industrial voltage safety regulations)
  • 910/920/931/931X: Custom project suffixes (matching specific equipment interface requirements of the project)

IV. 3-Step Quick Selection Technique (100% Accurate Matching)

Follow the interface type confirmation → core count & cable length matching → suffix selection logic to quickly lock the correct model, avoiding mechanical mismatch and functional non-compliance.

Step 1: Confirm Target Device Interface Type

• Standard control cabinet panel mounting → Select M16 interface series (non-M12 models, e.g., SACC-EC-MSD-4CON-M16)
• Compact field sensor/actuator connection → Select M12 interface series (e.g., SACCEC-M12MS-5CON)

Step 2: Match Core Count & Cable Length by Transmission Demand

• Core count selection:
  • Basic 2-channel signal transmission → 2-core models (e.g., SACCEC-M12FSB-2CON)
  • General 4/5-channel mixed transmission → 4/5-core models (most mainstream, e.g., SACC-EC-MSD-4CON)
  • High-density 8-channel signal transmission → 8-core models (e.g., SACC-EC-MS-8CON)
• Cable length selection:
  • Cabinet internal wiring → 0.5m short cable
  • Control cabinet to field device wiring → 1.0m/2.0m medium cable
  • Long-distance remote field device connection → 5.0m/10m long cable
  • Dust/waterproof field wiring → Select PG9 cable gland models

Step 3: Select Suffix According to Installation & Project Requirements

• Batch standardized assembly projects → Select SCO suffix models (improve installation efficiency)
• Voltage regulatory compliance required → Select VA suffix models (meet regional safety standards)
• Project-specific custom equipment interface → Select models with 910/920/931/931X suffix (match custom specifications)
• General industrial scenarios → Select standard no-suffix models (cost-effective)

V. Selection Pitfall Avoidance Guide (Critical for Connection Stability)

Avoid the 4 most common selection errors of the SACC-EC series to ensure mechanical matching, electrical safety and transmission stability in harsh industrial environments.

1. Interface Mismatch: M12 sensor connection using M16 interface models → Verify device interface size strictly, select M12 series for M12 sensors to avoid mechanical fit failure.
2. Suffix Neglect for Batch Projects: Using standard no-suffix models for large-scale batch installation → Select SCO suffix models to realize standardized assembly and improve on-site installation efficiency.
3. Cable Length Miscalculation: Short cables leading to tensioned wiring → Select longer cables or adjustable-length variants; avoid signal loss caused by cable stretching.
4. Custom Suffix Misuse: Using non-custom suffix models for project-specific equipment → Select models with matching 910/920/931X suffix to ensure interface compatibility with custom equipment.

VI. Conclusion: Core Connection Components for Industrial Automation Signal & Power Transmission

The Phoenix SACC-EC series delivers a targeted industrial circular connector solution covering M16/M12 dual interfaces, 2–8 core counts and diversified functional suffixes, perfectly adapting to control cabinet internal wiring, field device connection and batch standardized assembly scenarios. The SCO/VA/custom suffixes ensure installation efficiency, regulatory compliance and project customization, while the industrial-grade design guarantees stable operation in harsh environments.
