Phoenix Contact 1424451 HC-STA-A03PT-BWS-HS-M20-ELCAL Wire Connector, Cast Aluminium

The Phoenix Contact HC-STA-A03PT-BWS-HS-M20-ELCAL wire connector is a robust industrial-grade solution designed for secure and reliable electrical connectivity. Housed in a durable die-cast aluminium casing, this connector is engineered to withstand harsh operating conditions, including exposure to salt water, making it an ideal choice for demanding environments where protection and performance are critical.

Advantages

This connector set offers exceptional durability due to its high-quality die-cast aluminium construction, which provides superior mechanical strength and resistance to environmental factors. The integrated push-in connection technology allows for rapid and tool-free wire termination, significantly reducing installation time while ensuring a vibration-resistant and stable electrical contact. With an IP67 degree of protection, the unit is fully sealed against dust and water ingress, ensuring long-term reliability in outdoor or industrial settings.

Suitable for

• Industrial automation systems
• Marine and offshore electrical installations
• Outdoor machinery and control cabinets
• Applications requiring high resistance to salt water and corrosion

When it may not be suitable

This connector is specifically designed for industrial applications with a 3-position configuration and may not be suitable for high-density signal transmission or complex multi-core cabling requirements. It is not intended for use in consumer electronics or low-voltage residential wiring where standard modular connectors are typically employed.

Key specifications

• Material: Die-cast aluminium
• Degree of protection: IP67
• Number of positions: 3
• Connection method: Push-in connection
• Connection cross section: AWG 26 to 16
• Thread size: M20
• Weight: 135 g

How to use

To install the connector, prepare the wires by stripping them to the required length according to the terminal specifications. Insert the conductors directly into the push-in terminals until they are securely locked in place. Ensure the M20 thread is properly aligned and tightened to maintain the IP67 seal. The housing should be mounted securely to the target surface or enclosure to prevent mechanical strain on the connection points.

What to consider before purchase

• Verify that the 3-position configuration meets your circuit requirements.
• Ensure the M20 thread size is compatible with your existing cable glands or enclosure ports.
• Confirm that your wire gauge falls within the AWG 26-16 range.
• Check the environmental conditions to ensure the IP67 rating is sufficient for your specific application.

Usage recommendations

For optimal performance and to maintain the IP67 ingress protection rating, ensure that all seals are clean and free of debris before assembly. Regularly inspect the housing for signs of physical damage or corrosion if used in extreme environments.
