Product Overview
The Phoenix Contact 3003347 is a high-reliability plug-in connector designed for secure
signal and power transmission in industrial control systems. Part
of Phoenix Contact’s COMBICON series, this component ensures robust
connectivity in automation environments such as control cabinets,
motor control centers, and modular machinery. Its compact, modular
design supports DIN rail mounting (EN 60715), enabling
space-efficient integration into high-density panels. The connector
features a durable polyamide housing with IP20 protection, providing resistance to dust and minor mechanical impacts.
Engineered for versatility, the 3003347 accommodates both single-
and multi-conductor wiring, making it suitable for diverse
applications ranging from PLC interfaces to sensor networks.
Compliance with IEC 60947, UL 1059, and RoHS/REACH standards ensures global applicability and adherence to
environmental regulations. The push-in spring-cage clamping
technology allows tool-free installation, reducing assembly time
and minimizing wiring errors. Transparent housing enables quick
visual inspection of wire seating, simplifying maintenance in
complex systems.
Key Technical Parameters
The 3003347 is defined by precision-engineered specifications for
industrial durability:
- Rated Voltage: 250 V AC/DC
- Current Rating: 4 A (continuous), optimized for low-power control circuits.
- Wire Cross-Section: 0.14–0.75 mm² (fine-stranded) / 0.2–0.5 mm² (solid conductors).
- Temperature Range: -40°C to +85°C (operational), ensuring stability in harsh
environments.
- Contact Material: Tin-plated copper alloy for low resistance and corrosion
resistance.
- Insulation Resistance: >100 MΩ (at 500 V DC), minimizing leakage risks.
- Mounting: Compatible with 35 mm DIN rails for tool-free, snap-on installation.
- Safety Certifications: UL 94 V-0 (flammability), CE, and cULus listed.
These parameters make the 3003347 ideal for signal routing, sensor
networks, and low-voltage control systems.
Primary Applications
The 3003347 is widely deployed across industries requiring precise
electrical connectivity:
- PLC and Controller Wiring: Links sensors, actuators, and I/O modules to automation
controllers.
- Motor Control Systems: Connects low-power motor drivers and servo controls in
manufacturing lines.
- Energy Management: Routes signals in solar inverters, wind turbines, and battery
monitoring systems.
- Building Automation: Integrates into HVAC and lighting control systems for centralized
management.
- Transportation Infrastructure: Used in railway signaling and traffic control panels for reliable
operation.
Its vibration-resistant design also suits robotics, packaging
machinery, and mobile equipment, where stable connections are
critical. The connector’s modularity enables easy scalability,
supporting future system expansions.
Competitive Advantages
The 3003347 outperforms standard connectors through innovative
design:
- Tool-Free Installation: Push-in spring-cage technology reduces wiring time by 30% and eliminates screwdriver dependency.
- Space Optimization: Ultra-compact footprint allows dense stacking in control panels.
- Vibration Stability: Spring-loaded contacts maintain integrity in high-vibration
environments.
- Color-Coded Terminals: Simplifies wire identification and reduces installation errors.
- Eco-Friendly Compliance: Halogen-free and RoHS-compliant materials align with
sustainability goals.
These advantages translate to lower labor costs, enhanced system
uptime, and reduced risk of connection failures.
Functional Features
The 3003347 delivers advanced functionality for modern automation
needs:
- Bidirectional Signal Integrity: Ensures minimal signal loss for accurate data transmission.
- Polarized Design: Keyed mating surfaces prevent incorrect plug orientation.
- Self-Cleaning Contacts: Maintain conductivity over repeated mating cycles.
- Test Points: Integrated access for voltage/current measurement without
disassembly.
- Daisy-Chaining Support: Enables cascading connections for simplified network topologies.
Combined with Phoenix Contact’s rigorous quality assurance, the
3003347 is a trusted solution for engineers prioritizing precision,
safety, and scalability in industrial automation.
