In industrial automation, M12 connectors are the standard interface for sensors, actuators, and Ethernet devices, enabling stable signal/power transmission in harsh environments. The Phoenix VS-M12 series expands its portfolio with M12 male (MS) / female (FS) interfaces, diverse coding (A/B/C/E/R/X), and multi-functional variants (IP20 protection, RJ45 conversion, LED indication), covering 0.3m-20.0m cable lengths. With IP67/IP20 protection, shielded design (BPS), and compatibility with PROFINET/EtherNet/IP protocols, this series is widely used in factory automation, robotics, and field device interconnection. This guide integrates part number-model correspondence, core technical parameters, and scenario-specific recommendations to simplify selection and procurement.

III. VS-M12 Series Nomenclature Explained (Key to Model Understanding)

VS-M12[Interface Type][Special Feature]-[Protection/Connection]-[Coding]-[Function]/[Length]

• Interface Type:
  • MS = M12 male (plug); FS = M12 female (socket); MSD/FSD = M12 male/female dual-core (Ethernet).
• Special Feature:
  • S = Shielded; BPS/BP = Enhanced shielded; D = Dual-core (Ethernet).
• Protection/Connection:
  • IP20 = Control cabinet internal (IP20 防护); OE = Open-end (field-wired); RJ45 = RJ45 conversion.
• Coding: 93B/94B (B coding), 93E/94E (E coding), 94C (C coding), 93R (R coding), 93X (X coding) – matches M12 standard coding for protocol compatibility.
• Function: LI = LED status indication (power/signal status); OD = Outer diameter optimized.
• Length: 0.3m/0.5m/1.0m/2.0m/5.0m/10.0m/20.0m – fixed-length cables for different installation distances.

IV. 3-Step Quick Selection Technique (Easy for Beginners)

Step 1: Confirm Interface Type (Male/Female/Conversion)

• Sensor/actuator with female interface: M12 male (MS) series → 1412794, 1406056.
• Distribution box/control cabinet (female socket required): M12 female (FS) series → 1404206, 1412820.
• Ethernet device integration (RJ45 interface): M12-to-RJ45 conversion series → 1561797, 1657591.

Step 2: Select Coding Based on Protocol

• PROFINET/PROFIBUS: E coding (93E/94E) → 1406056, 1404206.
• General sensors/actuators: B coding (93B/94B) → 1403495, 1404368.
• Special protocols (e.g., CANopen): C coding (94C) → 1412794, 1412820.
• Ethernet (10G): X coding (93X/931) → 1561797, 1657591.
• Custom protocols: R/F coding (93R/94F) → 1416242, 1440656.

Step 3: Determine Protection & Special Requirements

• Field wiring (outdoor/harsh environment): OE (open-end) + IP67 → 1412794, 1405866.
• Control cabinet internal (stable environment): IP20 → 1406056, 1404205.
• Status monitoring: LI (LED indication) → 1412794, 1412820.
• High-interference environments: Shielded (S/BPS/BP) → 1440656, 1404206.
• Installation distance: Select length (0.3m-20.0m) → 0.3m (compact cabinets) → 1403157; 20m (long-distance) → 1440656.

V. Recommended Industry-Scenario Combinations (Ready-to-Use)

VI. Selection Pitfall Avoidance Guide (Common Mistakes to Note)

1. Coding mismatch: Using B coding for PROFINET (E coding required) → Confirm device protocol and select corresponding coding (E for PROFINET, A for EtherNet/IP) to avoid communication failure.
2. Interface type error: Sensor female interface using M12 female cable → Choose MS (male) for sensor female, FS (female) for sensor male.
3. Protection level neglect: Field wiring using IP20 models → Select OE (IP67) for outdoor/harsh environments to prevent water/dust damage.
4. Shielding missing: High-interference environments (near motors) using non-shielded models → Choose S/BPS/BP suffix (1440656, 1404206) to suppress EMI.
5. Length selection error: Overly long cables (＞20m) causing signal attenuation → Use 20m max (1440656) for M12, longer distances require fiber conversion.
6. LED indication oversight: Critical circuits needing status monitoring using non-LI models → Select LI suffix (1412794) for power/signal status visualization.
