Phoenix M23/M17 Series Industrial Heavy-Duty Connectors Selection Guide

Opening: High-Density Heavy-Duty Connectors for Industrial Power & Multi-Channel Signal Transmission

The Phoenix M23/M17 series encompasses industrial-grade heavy-duty circular connectors designed for harsh industrial scenarios, including robotic arms, large motors, and heavy machinery. These connectors cover core counts from 3-core to 17-core, support signal (S) and power (P) transmission, and feature specialized coding (1N/2N/198A) and length variants (24mm–600mm). With IP67 protection (when mated), anti-vibration construction, and wide operating temperatures (-40°C to +85°C), they ensure stable multi-channel power/signal transmission in high-load, high-interference industrial environments. This guide categorizes models by series, decodes nomenclature, and provides scenario-based recommendations for efficient selection.

I. Core Advantages of the M23/M17 Series

1. Dual-series coverage: M23 (heavy-duty, high-power) for large motors/robotic joints; M17 (compact heavy-duty) for medium-power multi-channel signal/power hybrid transmission, adapting to different installation space requirements.
2. Wide core count range: 3-core to 17-core configurations, supporting single-power, multi-signal, and power-signal hybrid transmission (e.g., 17-core for integrated motor power + encoder signal).
3. Specialized coding compatibility: 1N/2N/198A coding ensures exclusive matching with industrial devices, preventing cross-connection and signal interference.
4. Industrial-grade durability: Metal housing (for M23), high-temperature-resistant insulation, and anti-vibration design (up to 10g vibration resistance), suitable for factory floor and outdoor heavy machinery.
5. Flexible length/customization: Fixed-length variants (24mm–600mm) and custom coding (AW/AA) for device-specific adaptation, reducing on-site wiring modification.

III. M23/M17 Series Nomenclature Decoding

[Series]-[Core Count][Type]-[Coding]-[Length/Special Feature]

• Series:
  • M23 = Heavy-duty circular connector (for large motors, robotic joints, high-vibration scenarios);
  • M17 = Compact heavy-duty connector (for medium-power/medium-density scenarios with space constraints).
• Core Count:
  • 03/05/06/07/08/09/12/17 = Number of transmission cores (core count increases with transmission channel quantity; 17-core for ultra-high-density integration).
• Type:
  • S = Signal-type (for sensor/encoder/digital signal transmission, focus on signal integrity);
  • P = Power-type (for actuator/motor power transmission, focus on current-bearing capacity);
  • ES = Special signal-type (for high-precision/isolated signal, with enhanced anti-interference);
  • EP = Special power-type (for medium-high power with shielded/isolated protection).
• Coding:
  • 1N/2N = General industrial coding (1N for single-protocol, 2N for dual-protocol compatibility);
  • 198A/198AA = High-power motor-specific coding (for motor power/encoder matching);
  • 8A/8AA/8AW = Multi-protocol hybrid coding (for power-signal hybrid transmission).
• Length/Special Feature:
  • Length: 2/3/4/24/25/500/600 (mm, ultra-short for cabinet internal, long for field transmission);
  • S = Shielded (enhances EMI protection for high-interference environments);
  • DU = Dual-channel isolation (isolates different voltage/current signals to prevent cross-interference);
  • DNS/DUS = Custom signal/digital isolation (for specialized device compatibility);
  • L = Fixed-length cable (pre-terminated for plug-and-play).

IV. 3-Step Quick Selection Technique

Step 1: Select Connector Series Based on Equipment Type

• Heavy-duty large motors/robotic joints: Choose M23 series (e.g., 1628486 M23-7EP198AA500S, 1629080 M23-17P1N8AW600S) for high-power and vibration resistance.
• Medium-power/space-constrained machinery: Opt for M17 series (e.g., 1628518 M17-3ES1N8AA500S, 1629005 M17-17S1N8A8004S) for compact high-density transmission.

Step 2: Match Core Count to Transmission Channel Quantity

• 3-5 core: For simple power/single-group signal (e.g., 3-core sensor feedback, 5-core motor encoder, models 1628518/1628807).
• 6-9 core: For medium-density hybrid transmission (e.g., 6-core dual-power + dual-signal, 9-core multi-sensor, models 1629239/1629125).
• 12 core: For high-density signal/power (e.g., 12-core robotic arm multi-actuator, models 1069322/1628498).
• 17 core: For ultra-high-density integrated transmission (e.g., 17-core motor power + full-joint sensor, models 1341228/1629005).

Step 3: Select Coding & Special Features for Scenario Requirements

• Motor power/encoder connection: Pick 198A/198AA coding models (e.g., 1628486 M23-7EP198AA500S, 1628807 M23-5ES198A8L25) for device compatibility.
• High-interference environments: Add S (shielded) feature (all S-suffix models) to suppress EMI from inverters/motors.
• Mixed voltage/current signals: Choose DU (dual-isolation) models (e.g., 1341228 M23-17S1N1280DU, 1629220 M23-09S1N8A80DU) to prevent cross-interference.
• Cabinet-internal ultra-short wiring: Select 2-4mm ultra-short models (e.g., 1629239 M23-06S1N8A8002, 1628980 M17-8EP1N8A8002S) to save space.
• Field long-distance transmission: Use 500-600mm models (e.g., 1628495 M23-12S1N8AA600S, 1628927 M17-17S1N8AW500S) for cross-workshop connection.

V. Recommended Industry-Scenario Combinations

VI. Selection Pitfall Avoidance Guide

1. Series mismatch: Compact machinery using M23 connectors → Select M17 series (e.g., 1628518) to save installation space and avoid over-engineering.
2. Core count insufficiency: 17-channel sensor network using 12-core connectors → Choose 17-core models (e.g., 1341228/1629005) to avoid signal multiplexing and degradation.
3. Coding incompatibility: Motor encoder using general 1N coding connectors → Pick 198A/198AA motor-specific coding (e.g., 1628486) to ensure power/encoder signal matching.
4. Shielding neglect: High-EMI environments (inverters) using non-S models → Add S shielded feature (e.g., 1628788) to prevent signal distortion and device misoperation.
5. Isolation missing: Mixed voltage signals using non-DU models → Select DU dual-isolation models (e.g., 1341228) to avoid cross-voltage interference and circuit damage.
6. Length error: Cabinet-internal wiring using 500mm long connectors → Use 2-4mm ultra-short models (e.g., 1629239) to reduce cable clutter and signal attenuation.
