PT06A-14-18P-ND 18-Pin MIL-Spec Circular Connector, IP67

LD20/SP20 Industrial Flange Connector Dimensions and Specs

PT06A-14-18P-ND Connector Overview

The PT06A-14-18P-ND is a rugged 18-pin MIL-Spec circular connector designed for aerospace, avionics, and industrial electronics. Featuring a durable aluminum alloy shell with electroless nickel plating, this connector ensures reliable performance in harsh environments and extreme temperatures ranging from -55°C to +125°C.

The high-temperature thermoplastic insulator provides excellent electrical insulation and stability, while the solder cup termination guarantees secure and low-resistance connections. With IP67 protection, this connector is resistant to dust and water, making it ideal for demanding applications in industrial machinery, control systems, and transportation equipment.

Key Selection Criteria

When evaluating this connector for your application, consider the following decision points:

• Pin count and contact size: 18 pins with approximately 0.8 mm contact diameter, suitable for compact multi-signal routing.
• Electrical capacity: Rated at 7.5 A per contact and 600 VAC, with a test voltage of 1000 VAC for one minute.
• Environmental protection: IP67 rating provides dust-tight and temporary water immersion resistance for exposed installations.
• Termination method: Solder cup contacts require soldering during installation; verify your assembly capability.
• Standard compliance: Manufactured to MIL-DTL-26482 Series I specifications for interchangeability within this standard.

Application Suitability

This connector is well-suited for transportation and heavy machinery applications where vibration resistance and environmental sealing are critical. Typical uses include control systems, sensor interfaces, and power distribution in vehicles and industrial equipment.

For applications requiring higher pin counts or different mounting styles, review the PT Series Connectors Catalog to compare available configurations. The PT06A series is also available in other shell sizes and arrangements; consult the PT06A MIL-DTL-26482 Circular Connector Aluminum Alloy Plug for related options.

Installation Considerations

Before ordering, confirm the following details to ensure correct mating and installation:

• Mating connector part number and shell size compatibility
• Required pinout or wiring diagram for your specific circuit
• Cable outside diameter and conductor size for proper strain relief
• Mounting orientation and panel cutout dimensions
• Environmental exposure conditions beyond the IP67 rating

Performance Verification

The connector's insulation resistance is rated at ≥5000 MΩ, and contact resistance is ≤5 mΩ, confirming stable electrical performance over its service life. These values are verified during production testing to meet MIL-DTL-26482 requirements.

For applications with extreme temperature cycling or continuous high-current loads, confirm that the 7.5 A per contact rating aligns with your derating requirements. The -55°C to +125°C operating range covers most industrial and transportation environments.

Ordering and Inquiry Checklist

When requesting a quotation, provide the following information to ensure accurate matching:

• Complete part number including any suffix variations
• Mating connector part number and gender
• Required cable type, diameter, and conductor gauge
• Quantity and delivery schedule
• Any special plating or marking requirements

For applications outside the standard PT06A configuration, contact our engineering team to discuss custom solutions. Provide your mechanical drawing or pinout specification for evaluation.
