Phoenix SACC-M12MSB/SACC-M12MS Series Industrial M12 Circular Connectors Selection Guide

Opening: Precision M12 Connectivity Solutions for Industrial Signal & Power Transmission

The Phoenix SACC-M12MSB and SACC-M12MS series represent industrial-grade M12 circular connectors engineered for reliable signal, power, and data transmission in factory automation, robotics, and industrial control systems. Covering two core sub-series—SACC-M12MSB (5-core specialized) and SACC-M12MS (4/5-core versatile)—these connectors feature M12 industry-standard interfaces, 2/3/4/5-core configurations, and functional variants (signal: SC; power: PL; coded signal: QO; general connection: CON). Key attributes include shielded (SH) EMI protection, IP67 ingress protection (when mated), diverse cable gland options (PG7/9/11, DM diameter ranges), and regional certifications (AU/VA/IB). Widely used for sensor/actuator wiring, industrial Ethernet, and power distribution, they ensure robust performance in harsh industrial environments.

V. Recommended Industry-Scenario Combinations

VI. Selection Pitfall Avoidance Guide

1. Core Count Mismatch: 4-channel sensors using 5-core connectors → Select 4-core variants (e.g., 1513253/1641785) to avoid unused contacts and wiring inefficiency.
2. Function Type Error: Power transmission using SC-type connectors → Choose PL-type (e.g., 1424662/1424666) for enhanced current handling and safety.
3. Cable Gland Incompatibility: 8mm cables using PG7 glands → Match gland size to cable diameter (PG9 for 7-9mm, DM 5-8 for variable diameters) to ensure IP67 protection.
4. Shielding Neglect: High-interference environments (inverters/motors) using non-SH connectors → Select SH variants (e.g., 1513570/1501540) to prevent signal distortion.
5. Regional Certification Missing: Australian projects using non-AU connectors → Choose AU-certified variants (e.g., 1507764) to meet local regulatory requirements.
6. Wire Gauge Mismatch: 0.75mm² cables using 0.34mm² QO connectors → Match QO-type wire gauge (e.g., 1641785 for 0.75mm²) to ensure reliable signal transmission.
7. Special Feature Overlooking: Space-constrained installations using standard-profile connectors → Opt for SKIN thin-profile (e.g., 1556870) or XL extended-length (e.g., 1401096) variants.
