Phoenix SACC Series Industrial Connectors (SQ/P12/MS Series) Selection Guide

Opening: High-Density M12/P12 Industrial Connectors for Signal/Power Interconnection

The Phoenix SACC series (SQ/P12/MS sub-series) covers M12/P12 industrial connectors for automation systems, including SQ (square-base M12), P12 (12mm circular), and MS (standard M12) variants. These connectors support 4-8 core configurations, PROFINET (PN) protocol, shielded (SH) designs, and diverse cable gland sizes (PG7/9/11), with features like right-angle (L180) installation and compact (CM) housing. Widely used in sensor/actuator wiring, PLC communication, and fieldbus systems, they ensure stable transmission in harsh industrial environments. This guide categorizes models by sub-series, decodes nomenclature, and provides scenario-based recommendations for efficient selection.

I. Core Advantages of the SACC Series (SQ/P12/MS)

1. Multi-interface coverage: M12 (MS/FS) and P12 (MSD/MRD) interfaces adapt to different industrial device standards, with square-base (SQ) for space-constrained cabinets and circular (P12/MS) for general field wiring.
2. Protocol & shielding compatibility: Built-in PROFINET (PN) support for industrial Ethernet, and shielded (SH) designs to suppress electromagnetic interference (EMI) in high-noise environments.
3. Flexible configuration: 4-8 core counts for signal/power integration, PG7/9/11 cable glands for different cable diameters, and right-angle (L180) mounting for cabinet-edge wiring.
4. Industrial durability: IP67 protection (when mated), -40°C to +85°C operating temperature, and anti-vibration construction for factory floors and outdoor installations.

III. SACC Series Nomenclature Decoding

1. SACC-SQ Series

SACC-SQ-[M12 Interface]-[Core Count/Type]-[Cable Spec]-[Special Feature]

• M12 Interface: MS (male straight)/FS (female straight) → M12 connector gender and orientation.
• Core Count/Type: 4CON/5CON/8CON → Number of cores (CON = connection-type terminal).
• Cable Spec: 20/0,5 → 20 AWG wire gauge + 0.5m fixed cable length (no unit = custom length).
• Special Feature: L180 = 180° right-angle mounting (for cabinet-edge wiring).

2. SACC-P12/PO12 Series

SACC-[P12/PO12 Interface]-[Core Count/Type]-[Terminal Type]-[Special Feature]

• P12/PO12 Interface: MSD (male D-code)/MRD (male reverse D-code)/MSX (male X-code)/FSD (female D-code) → 12mm connector coding (D=PROFINET, X=high-speed Ethernet).
• Core Count/Type: 4CT/5CT/8CT/4PL → CT (clamp terminal)/PL (pin-type terminal), core count.
• Terminal Type: CM (compact)/CL (clamp) → Installation form (space-saving or quick-wiring).
• Special Feature: SH (shielded)/PN (PROFINET compatible) → EMI protection or protocol support.

3. SACC-MS/MSD/MSB Series

SACC-[MS/MSD/MSB]-[Core Count/Coding]-[Gland/Feature]-[SCO]

• Base Interface: MS (standard M12)/MSD (male D-code)/MSB (male B-code) → M12 connector base type.
• Core Count/Coding: 4SC/5SC (SC coding, general signal)/4QO/5QO (QO protocol)/4CON/5CON (cable gland connection).
• Gland/Feature:
  • PG7/9/11 = cable gland size (matches cable diameter: PG7=small, PG9=standard, PG11=large);
  • M = fixed mounting (cabinet-installed);
  • DUO = dual-mode wiring (power/signal hybrid);
  • PB/PBPA = push-button terminal (quick-wiring);
  • SH = shielded;
  • PN = PROFINET compatible.
• SCO: Shielded cable outlet (enhances EMI protection for cable entry).

IV. 3-Step Quick Selection Technique

Step 1: Select Interface Type Based on Installation Scenario

• Compact cabinet wiring: SACC-SQ series (square base, e.g., 1419784 SACC-SQ-M12MS-4CON-20/0,5) to save space.
• PROFINET/Ethernet communication: SACC-P12/PO12 series with PN suffix (e.g., 1021830 SACC-PO12MSD-4CT-CM SH PN) for protocol compatibility.
• General field wiring: SACC-MS/MSD/MSB series (standard M12, e.g., 1432648 SACC-MS-5SC SH SCO) for versatile signal/power connections.

Step 2: Match Core Count & Coding to Transmission Needs

• 4-core signal/Ethernet: 4SC/4CT/4CON (e.g., 1432729 SACC-MS-4SC SH SCO for signal, 1021830 for PROFINET).
• 5-core power/signal hybrid: 5SC/5QO/5CON (e.g., 1413991 SACC-MS-5QO-0,75 SH SCO for QO protocol, 1542978 for PG9 cable).
• 8-core high-density signal: 8CT/8CON (e.g., 1021783 SACC-P12MSX-8CT-CL SH for industrial camera data).

Step 3: Choose Special Features for Environmental/Function Requirements

• High-EMI environments: Select SH (shielded) models (e.g., 1432648 SACC-MS-5SC SH SCO) to suppress interference.
• PROFINET networks: Pick PN suffix models (e.g., 1021830) for seamless protocol integration.
• Cabinet-edge wiring: Opt for L180 right-angle models (1456446 SACC-SQ-M12FS-5CON-20-L180).
• Fixed cabinet installation: Use M (fixed mounting) models (e.g., 1432567 SACC-MS-5SC M SCO).
• Cable diameter matching: Choose PG7/9/11 gland models (e.g., 1542952 for PG7, 1543016 for PG11).

V. Recommended Industry-Scenario Combinations

VI. Selection Pitfall Avoidance Guide

1. Protocol mismatch: PROFINET systems using non-PN models → Select P12/PO12 series with PN suffix (e.g., 1021830) to ensure communication stability.
2. Cable gland size error: Large-diameter cable using PG7 gland → Match gland size (PG7=small, PG9=standard, PG11=large) to cable diameter (e.g., 1543016 for PG11).
3. Shielding neglect: High-EMI environments using non-SH models → Choose SH suffix (e.g., 1432648) to suppress interference and prevent signal loss.
4. Installation space error: Narrow cabinets using circular (MS) connectors → Opt for square-base SQ series (e.g., 1419784) to save 20% cabinet space.
5. Core count insufficiency: 8-channel sensor using 5-core connectors → Select 8-core models (e.g., 1441697, 1021783) to avoid signal multiplexing and degradation.
6. Right-angle requirement missing: Cabinet-edge wiring using straight connectors → Use L180 models (1456446) to reduce cable bending and extend service life.
