NORDEL NLHC255T Hermetic Connector, 5-Pin, 24A, 450V, 0.5–2.5 mm², IP68

The NORDEL NLHC255T is a professional-grade hermetic connector engineered to provide secure and reliable electrical connections in challenging environmental conditions. This 5-pin connector is built to withstand moisture and dust ingress, ensuring long-term stability for critical electrical circuits. With its robust construction and high-performance sealing, it serves as an essential component for installations where protection against the elements is paramount.

Advantages

This connector offers exceptional durability due to its IP68 ingress protection rating, which guarantees complete protection against dust and prolonged immersion in water. The design supports a versatile range of wire cross-sections from 0.5 to 2.5 mm², providing flexibility for various electrical wiring projects. Its high electrical capacity, rated at 24A and 450V, allows it to handle demanding power requirements safely and efficiently. The compact and secure locking mechanism ensures that connections remain stable even when exposed to vibrations or external mechanical stress.

Suitable for

• Outdoor lighting installations
• Industrial equipment and machinery
• Garden and landscape electrical systems
• Submersible pump connections
• Waterproof junction boxes

When it may not be suitable

This connector is not intended for use in high-temperature environments that exceed the material's thermal rating or in applications involving aggressive chemical exposure that could degrade the sealing gaskets. It is also not suitable for high-voltage power distribution networks exceeding the specified 450V limit.

Key specifications

• Number of pins: 5
• Rated current: 24A
• Rated voltage: 450V
• Wire cross-section range: 0.5–2.5 mm²
• Ingress protection: IP68
• Cable diameter compatibility: 5–9 mm, 9–12 mm, and 10–14 mm

How to use

To install the connector, first strip the insulation from your wires to the appropriate length. Insert the wires into the designated terminals and ensure they are securely fastened. Assemble the housing components, ensuring that the sealing gaskets are correctly seated to maintain the hermetic seal. Tighten the cable glands firmly to secure the cable and prevent moisture from entering the housing. Verify that all parts are locked in place before energizing the circuit.

What to consider before purchase

• Ensure the cable diameter matches one of the supported ranges (5–9, 9–12, or 10–14 mm).
• Verify that the total current and voltage of your circuit do not exceed the connector's ratings.
• Check that the number of pins matches your wiring requirements.

Usage recommendations

Always ensure that the cable glands are tightened sufficiently to compress the internal seals, as this is critical for maintaining the IP68 rating. Periodically inspect the connection if it is located in an area subject to extreme weather conditions.
