Electrical Contact Harting 09691817423, Copper Alloy, AWG min.10 max.8, 40 A

Harting electrical contact 09691817423 is a single replaceable contact element produced from a copper alloy, designed to fit Harting connector systems and compatible assemblies. It supports conductor sizes from AWG 10 to AWG 8 and is rated for continuous current up to 40 A, making it suitable for medium-current signal and power connections in industrial and automation environments.

Advantages

The copper-alloy construction offers a balance of electrical conductivity and mechanical strength for repeated mating cycles. The contact is sized and shaped to integrate with Harting housings and inserts, ensuring consistent contact pressure and low contact resistance. Its rated current capability provides margin for many control, signal-power and distribution tasks while maintaining compact connector form-factors.

Suitable for

• Replacement of worn or damaged contacts in Harting connector inserts and housings
• Medium-current power distribution and control circuits up to 40 A
• Industrial automation equipment and machinery where robust connector performance is required
• Signal-power hybrid connectors combining control and power in a single assembly

When it may not be suitable

This contact is intended for conductor cross-sections corresponding to AWG 10–8 and a rated current of 40 A. It is not suitable for applications that require higher continuous currents or larger conductor sizes, or for installations that demand specialized contact plating or exotic alloys for extreme corrosion resistance. For connectors outside the Harting family or for assemblies with incompatible contact geometries, this part will not provide correct fit or reliable electrical performance.

Key specifications

• Contact material: copper alloy
• Conductor compatibility: AWG 10 to AWG 8
• Rated continuous current: 40 A
• Intended use: replaceable contact element for connector inserts/housings
• Typical applications: industrial signal and power connections

How to use

Install the contact by inserting it into the appropriate Harting connector insert or housing following the connector manufacturer's assembly guidance. Ensure conductors are prepared to the specified AWG sizes, stripped to the correct length, and either crimped or terminated according to the recommended method for this contact type. After installation, verify mechanical retention and electrical continuity before energizing the circuit. When replacing a contact, power down the system, remove the old contact carefully to avoid damage to the insert, and fit the new contact in the same orientation.

What to consider before purchase

• Confirm mechanical compatibility with your Harting connector insert or housing model
• Verify that conductor sizes (AWG 10–8) match your wiring needs
• Check that a 40 A rated contact is sufficient for continuous current requirements
• Determine if special surface plating or enhanced corrosion resistance is required for your environment

Usage recommendations

Use appropriate crimping or termination tools recommended for the contact type, follow Harting assembly instructions, and perform routine inspections of contact retention and contact resistance in regular maintenance intervals to ensure ongoing reliable performance.
