Phoenix ST Series Industrial Electronic Components Selection Guide

Opening: Versatile Electronic Components for Industrial Control & Circuit Protection

The Phoenix ST series encompasses a diverse range of industrial-grade electronic components including low-voltage terminals/protection modules (ST-06/10/20KS/KP), signal conditioning modules (ST-17S/P series), and rectifier diodes (ST-1N4007). These components are engineered for harsh industrial environments, with specifications tailored to different current/voltage ratings, signal types, and circuit protection needs, widely used in control cabinet circuits, sensor signal processing, and power rectification scenarios. This guide categorizes models by function, decodes their nomenclature, and provides scenario-based selection recommendations to streamline procurement and application.

I. Core Advantages of the ST Series

1. Multi-category coverage: Integrates passive components (diodes), signal modules, and terminal protection components, eliminating the need for multi-vendor sourcing for industrial circuits.
2. Graded specification matching: The 06/10/20 series (06=6mm, 10=10mm, 20=20mm dimension/class) adapts to different circuit current levels, while the 17S/P series supports precise signal conditioning for industrial sensors.
3. Industrial durability: Wide operating temperature range (-40°C to +85°C), anti-vibration design, and compatibility with industrial circuit standards, ensuring stable performance in factory environments.
4. Standardized interface: Uniform pin and mounting dimensions for seamless integration with Phoenix terminal blocks and control cabinets, reducing installation adaptation time.

III. ST Series Nomenclature Decoding

1. ST-06/10/20KS/KP Series

ST-[Dimension Class][Type][Parameter Code]

• Dimension Class: 06/10/20 → Represents the physical size or rated current class (06=6mm compact, 10=10mm standard, 20=20mm medium-power).
• Type:
  • KS = Signal/control type (for low-current control/signal circuits, focus on signal integrity);
  • KP = Power/protection type (for medium-current power circuits, focus on overcurrent/overvoltage protection).
• Parameter Code: 010/020/030/035 → Indicates specific electrical parameters (e.g., 010=low threshold, 035=high-precision signal threshold, 020=standard power threshold).

2. ST-17S/P Series

ST-17[Type][Chip Model][Interface Code]

• 17: Fixed 17mm physical size for compact control cabinet installation.
• Type:
  • S = Signal-type (for sensor signal conditioning, filtering, and conversion);
  • P = Power-type (for sensor/device power signal stabilization and protection).
• Chip Model: 1N8A → Core signal/power conditioning chip specification (matches industrial sensor signal levels).
• Interface Code: CK04S/8003S/9K03S → Interface type and pinout (compatible with different sensor/PLC interfaces).

3. ST-1N4007

ST-[Diode Model]

• Directly uses the industry-standard diode model 1N4007, indicating it is a Phoenix-branded industrial-grade 1A/1000V rectifier diode.

IV. 3-Step Quick Selection Technique

Step 1: Determine Component Type Based on Circuit Function

• Power rectification/reverse protection: Select ST-1N4007 (for 1A/1000V low-power AC-DC circuits).
• Signal conditioning/processing: Choose ST-17S/P series (S for pure signal, P for power signal with protection).
• Terminal connection/protection: Opt for ST-06/10/20KS/KP series (KS for signal terminals, KP for power terminals).

Step 2: Match Dimension/Class to Installation & Current Requirements

• Ultra-compact cabinets (6mm space): ST-06 series (e.g., 1607580 ST-06KS010 for signal, 1607577 ST-06KP010 for power).
• Standard control circuits (10mm space): ST-10 series (e.g., 1618239 ST-10KS010 for low-current signal, 1618458 ST-10KP035 for high-threshold power).
• Medium-power circuits (20mm space): ST-20 series (e.g., 1607657 ST-20KS010 for control signal, 1607655 ST-20KP010 for basic power).

Step 3: Select Specific Parameters & Interfaces

• High-precision signal conditioning: ST-17S1N8ACK04S (1618836, CK04S compact interface) for analog sensor signals.
• Power signal stabilization: ST-17P1N8A9K03S (1613896, 9K03S high-threshold interface) for sensor power circuits.
• Standard terminal protection: Choose 010/020 parameter codes (e.g., 1607657 ST-20KS010) for general circuits; 030/035 for high-precision/high-threshold scenarios.

V. Recommended Industry-Scenario Combinations

VI. Selection Pitfall Avoidance Guide

1. Type mismatch (KS vs. KP): Signal circuits using KP-type modules → Choose KS series (e.g., 1618239 ST-10KS010) to avoid signal attenuation; power circuits using KS → Select KP (e.g., 1618458 ST-10KP035) for sufficient protection.
2. Dimension/class error: 6mm compact cabinets using 20mm modules → Opt for ST-06 series (1607580) to save space and ensure fit.
3. Parameter code neglect: High-precision sensor signals using 010 low-threshold modules → Choose 030/035 codes (e.g., 1618464 ST-10KS035) for matching signal levels.
4. Diode overrating: 1A rectification using non-1N4007 components → Use ST-1N4007 (2802329) for industry-standard 1A/1000V rectification; avoid oversize diodes for cost and space waste.
5. Interface incompatibility: Sensor signals using mismatched CK04S/8003S interfaces → Confirm sensor/PLC interface type, select 17S/P series with matching interface codes (e.g., 1618836 for CK04S, 1607642 for 8003S).
