Phoenix QPD Series Industrial Cable Entry & Wiring Systems Selection Guide

Opening: Integrated Cable Fixing, Sealing & Wiring Solutions for Industrial Enclosures

The Phoenix QPD series is a modular industrial cable entry and wiring system that combines cable gland sealing, strain relief, and terminal connection functions. It covers multiple sub-series (W/T/QSK/P/H/C/CW) with diverse core counts (2PE/3PE/4PE), wire gauges (1.5/2.5/6.0mm²), and cable outer diameter ranges (4-20mm), as well as color options (BK black/GY gray). Widely used in control cabinet cable entry, field device wiring, and multi-channel signal/power distribution, this series ensures IP65-level sealing, reliable cable fixation, and standardized wiring, adapting to harsh industrial environments. This guide structures part number-model correspondence, core parameters, and scenario recommendations to simplify selection and procurement.

I. Core Advantages: Why Choose the QPD Series?

1. Integrated multi-function design: Combines cable gland (sealing/strain relief), terminal block (wiring), and mounting base (fixation) into one, eliminating the need for separate components and reducing installation steps by 40%.
2. Wide cable compatibility: Supports wire gauges of 1.5/2.5/6.0mm² and cable outer diameters of 4-20mm, matching signal lines (1.5mm²), power cables (2.5/6.0mm²), and different types of industrial cables.
3. Diverse installation modes: Covers wall-through (W), multi-channel terminal (T), quick-connect (QSK), panel-mount (P), multi-row (H), single/double-channel (C/CW) sub-series, adapting to cabinet walls, panels, and distribution boxes.
4. Industrial-grade protection: IP65 sealing (when matched with appropriate gaskets), -40°C to +85°C operating temperature, oil/dust resistance, and anti-vibration cable fixation to ensure long-term stability.
5. Standardized color coding: BK (black) for general scenarios, GY (gray) for visual differentiation of critical circuits, facilitating on-site maintenance and identification.

• Cable OD/Mounting Hole Spec:
  • Cable OD range (e.g., 4-9/6-10/9-14mm) = 适配电缆外径；
  • Mounting hole spec (e.g., 3X4-9/4X6-10) = mounting hole quantity × diameter range.
• Gland/Installation Type:
  • M20/M25 = cable gland thread size (matches cable OD);
  • TL = terminal lock (anti-loosening); DT = double terminal (dual connection).
• Special Feature/Length:
  • FC = fast-connect (quick terminal); FS = fast snap-in (QSK series);
  • 0.5/1.0 = fixed lead length (meter) after cable entry.
• Color: BK = black (general); GY = gray (critical circuit identification).

IV. 3-Step Quick Selection Technique

Step 1: Select Sub-series Based on Installation Mode

• Cabinet wall cable entry: W series (e.g., 1423980, 1414676) → integrated gland + wiring.
• Centralized multi-channel wiring: T series (3-row, e.g., 1411414) or H series (4-row, e.g., 1411422) → high-density distribution.
• Batch quick wiring: QSK series (FS fast snap-in, e.g., 1414728) → reduce installation time.
• Cabinet panel mounting: P series (e.g., 1410386, 1582637) → front/back panel dedicated entry.
• Dedicated circuit (space-constrained): C (single-channel, e.g., 1423991) or CW (double-channel, e.g., 1423965) → dedicated circuit isolation.

Step 2: Match Core Count & Wire Gauge (Based on Cable Specifications)

• Signal cables (low-current): 1.5mm² (e.g., 1414676 3PE1.5, 1414712 2PE1.5) → sensor/communication lines.
• Power cables (medium-current): 2.5mm² (e.g., 1423980 3PE2.5, 1423971 H3PE2.5) → actuator/motor power lines.
• High-power cables: 6.0mm² (e.g., 1411414 T4PE6.0, 1410415 C4PE6.0) → main power distribution lines.
• Core count: 2PE (dual signal/power) → 1414684; 3PE (3-core control) → 1423980; 4PE (4-core power) → 1410386; 5-core (multi-channel) → 1414728 (QSK).

Step 3: Confirm Cable OD & Special Requirements

• Cable OD matching:
  • Small OD (4-9mm): M20 gland (e.g., 1414676 W3PE1.5 4-9 M20);
  • Medium OD (6-10/9-14mm): M25 gland (e.g., 1423980 W3PE2.5 9-14 M25);
  • Large OD (12-20mm): P series 12-20mm spec (1410387 P4PE6.0 12-20).
• Special functions:
  • Quick wiring: FC (W series, 1414686) or FS (QSK series, 1414728);
  • Critical circuit identification: GY color (1423995 H4X2.5 GY, 1423965 CW3PE2.5 GY);
  • Anti-loosening: TL terminal lock (1039564 P4PE6.0 TL);
  • Fixed lead length: 0.5m (1423980) or 1.0m (1414676) for internal wiring.

V. Recommended Industry-Scenario Combinations

VI. Selection Pitfall Avoidance Guide

1. Cable OD-gland mismatch: Large OD (12mm) using M20 gland (4-9mm) → Match gland size (M20=4-9mm, M25=9-14mm) to cable outer diameter.
2. Core count/wire gauge error: 4-core power cable using 3PE model → Select 4PE (e.g., 1410386) or 4X core (QSK 1414758) for full-core wiring.
3. Installation mode mismatch: Cabinet front panel entry using W (wall-through) series → Choose P series (e.g., 1582202) for panel mounting.
4. Quick wiring neglect: Batch installation using standard terminals → Opt for QSK (FS) or W (FC) models (1414728, 1414686) to save time.
5. Critical circuit identification missing: Emergency circuits using BK color → Select GY (1423965, 1423995) for visual differentiation.
6. High-density requirement oversight: 8-channel wiring using 3-row T series → Use 4-row H series (e.g., 1411422) for more channels.
7. Sealing level neglect: Outdoor applications using single-seal models → Choose P series dual BK (1582637) for enhanced IP65 sealing.
