Phoenix SH Series 8-Core Industrial Connectors Selection Guide

Opening: High-Density 8-Core Connection Solutions for Industrial Signal & Power Transmission

The Phoenix SH series is a portfolio of industrial-grade 8-core connectors designed for reliable signal and power transmission in harsh factory environments. Covering signal (ES series) and power (EP series) categories, these connectors support diverse voltage specifications (48/58/68/008) and feature specialized coding (LD/LB/AWA) and locking structures for anti-vibration and anti-misconnection. With IP67 protection (when mated), wide operating temperature (-40°C to +85°C), and anti-corrosion housing, they are widely used in robotic workstations, production line sensors, and industrial actuator connections, ensuring stable multi-channel transmission in high-interference and high-vibration scenarios.

I. Core Advantages of the SH Series

1. Dual-category coverage:
   • ES series (signal): For 8-channel low-voltage signal transmission (e.g., sensor feedback, encoder signals), with anti-interference shielding and precise coding;
   • EP series (power): For 8-channel medium-power distribution (e.g., actuator power, module power supply), with high current-bearing capacity and overload protection.
2. Multi-specification compatibility: Supports 48/58/68/008 voltage/interface specifications, adapting to different industrial control system voltage levels and interface standards.
3. Industrial-grade reliability:
   • IP67 protection (when mated) for dust and water resistance, suitable for outdoor/harsh workshop environments;
   • Zinc alloy housing with anti-corrosion plating, resistant to salt spray and chemical corrosion;
   • Anti-vibration locking structure (LD/LB series), ensuring connection stability under 10g vibration (robotic joints/machinery).
4. Anti-misconnection design: Specialized coding suffixes (AWA/AAC/LD/LB) prevent cross-connection of different voltage/signals, reducing system faults.
5. Modular installation: DIN rail or panel-mounted options, compatible with Phoenix control cabinet infrastructure for seamless integration.

II. Product Classification & Detailed Parameter Table

The SH series is categorized into signal-type (ES) and power-type (EP) by function, with sub-variants based on voltage specification and coding.

1. ES Series (8-Core Signal Connectors)

For 8-channel low-voltage industrial signal transmission, including ESS/ESD/ESC sub-types with different signal precision and coding.

2. EP Series (8-Core Power Connectors)

For 8-channel medium-power distribution, including EPS/EPD/EPC/EP00 sub-types for different power specifications and coding.

III. SH Series Nomenclature Decoding

SH-8[Function Type][Spec Code][Coding Suffix][Special Feature]

• SH: Product series identifier (8-core industrial connector for signal/power transmission).
• 8: Fixed core count (8-channel, for multi-point signal or power distribution).
• Function Type:
  • ES = Signal-type (sub-divided into ESS/ESD/ESC: ESS=standard signal, ESD=high-precision signal, ESC=special signal);
  • EP = Power-type (sub-divided into EPS/EPD/EPC/EP00: EPS=standard power, EPD=high-power, EPC=special power, EP00=universal power).
• Spec Code:
  • 48/58/68/008 = Voltage/interface specification code (48=standard low-voltage, 58=special legacy spec, 68=high-precision signal spec, 008=universal power spec).
• Coding Suffix:
  • AWA00/AAC00 = General protocol coding (for system compatibility);
  • A8/A9 = Coding level (A8=standard coding, A9=enhanced anti-vibration coding);
  • LDL = Anti-vibration locking coding (for robotic/machinery scenarios);
  • LB1/LB2/LB3 = Mechanical locking coding (LB1=basic lock, LB2=medium lock, LB3=heavy-duty lock).
• Special Feature:
  • S = Shielded (enhanced EMI protection for signal/power);
  • SX = Enhanced shielded (for high-precision signal);
  • No S suffix = Non-shielded (for low-interference cabinet-internal scenarios).

IV. 3-Step Quick Selection Technique

Step 1: Select Function Type Based on Transmission Demand

• 8-channel signal transmission: Choose ES series;
  • Standard sensor signals: ESS sub-type (e.g., 1621568 SH-8ESS48AWA00S);
  • High-precision vision/encoder signals: ESD sub-type (e.g., 1238527 SH-8ESD68A8LB2SX);
  • Legacy/custom 58-spec signals: ESC sub-type (e.g., 1621567 SH-8ESC58AWA00S).
• 8-channel power distribution: Select EP series;
  • Standard indicator/actuator power: EPS sub-type (e.g., 1621570 SH-8EPS48AWA00S);
  • High-power heater/actuator power: EPD sub-type (e.g., 1157072 SH-8EPD68A8LB2S);
  • Legacy 58-spec power: EPC sub-type (e.g., 1621549 SH-8EPC58A9LDLS);
  • Universal multi-voltage power: EP00 sub-type (1627077 SH-8EP008A8LDLS).

Step 2: Match Spec Code to System Voltage/Protocol

• 48-spec systems: Select 48 suffix models (all ESS/EPS 48-spec variants) for standard industrial low-voltage signal/power;
• 58-spec legacy systems: Pick 58 suffix models (ESC/EPC 58-spec variants) for custom legacy equipment;
• 68-spec high-precision systems: Choose 68 suffix models (ESD/EPD 68-spec variants) for high-precision signal/high-power transmission;
• Universal multi-voltage systems: Opt for 008-spec EP00 model (1627077) for mixed-voltage power distribution.

Step 3: Add Coding/Special Features for Environmental Needs

• High-vibration scenarios (robots/machinery): Select LDL anti-vibration coding (e.g., 1621524 SH-8ESS48A8LDLS, 1621534 SH-8EPS48A8LDLS);
• Mechanical locking needs: Pick LB1/LB2/LB3 locking coding (LB3 for heavy-duty, e.g., 1621541 SH-8ESC58A9LB3S);
• High-interference environments: Choose S/SX shielded models (SX for high-precision signal, e.g., 1238527 SH-8ESD68A8LB2SX);
• Cabinet-internal low-interference scenarios: Use non-shielded models (no S suffix, e.g., 1621997 SH-8ESC58A8LDL).

V. Recommended Industry-Scenario Combinations

VI. Selection Pitfall Avoidance Guide

1. Function type mismatch: Power distribution using ES signal connectors → Select EP power series (e.g., EPS/EPD) to avoid current overload and connector burnout.
2. Spec code error: 58-spec legacy systems using 48-spec connectors → Pick 58-spec ESC/EPC models (e.g., 1621567) to ensure protocol/voltage compatibility and prevent signal/power failure.
3. Vibration scenario oversight: Robotic workstations using non-LDL coding connectors → Choose LDL anti-vibration models (e.g., 1621524) to avoid connection loosening and signal/power loss.
4. Shielding neglect: High-interference environments using non-shielded models → Select S/SX shielded variants (e.g., 1238527) to suppress EMI and ensure signal integrity.
5. Locking coding insufficiency: Heavy machinery using LB1 basic locking → Opt for LB3 heavy-duty locking (e.g., 1621541) to prevent connector disengagement under mechanical impact.

Conclusion: Select the Right SH Connector for 8-Core Industrial Transmission
