PT02A-8-4S MIL-Spec Connector Overview

The PT02A-8-4S is a compact, high-performance MIL-Spec circular connector designed for industrial electronics, automation systems, and other precision applications. Built to withstand harsh environments, it offers reliable electrical connections and long-lasting durability.

Key Selection Criteria

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

• Configuration: This model is a 4-pin receptacle (socket) with solder cup termination, suitable for panel or cable mounting where secure wire connections are required.
• Electrical Performance: Rated at 5A per contact and 250V AC/DC, it supports moderate power and signal transmission needs in control and automation circuits.
• Environmental Protection: With an IP67 rating when properly sealed, it is dust-tight and protected against temporary water immersion, making it suitable for demanding industrial environments.
• Material Durability: The aluminum alloy shell with anodized or chrome-plated finish provides corrosion resistance, while gold-plated brass contacts ensure stable conductivity.
• Temperature Tolerance: Operating from -55°C to +125°C, it accommodates both cold-start conditions and heat-generating equipment enclosures.

Application Fit and Boundaries

This connector is well-suited for industrial control systems, automation equipment, electronic devices, and environments requiring MIL-Spec reliability. Its compact design makes it suitable for tight spaces while maintaining performance and durability.

However, it is not recommended for applications requiring high-current power transmission above 5A per contact, or for environments where the connector will be frequently mated and unmated under load. For continuous submersion or high-vibration applications, verify that the mating plug and cable sealing are correctly specified.

Installation and Mating Considerations

Before ordering, confirm the mating plug configuration, pinout or wiring diagram, and cable outside diameter to ensure proper sealing and strain relief. Solder cup termination requires careful preparation of conductor ends to avoid solder bridges between adjacent contacts.

Quality and Reliability Notes

The connector's insulation resistance of ≥5000 MΩ and contact resistance of ≤5 mΩ indicate stable electrical performance under normal operating conditions. Test voltage of 1000V AC for 1 minute confirms dielectric strength for the rated voltage class.

Inquiry Checklist

To receive an accurate quotation and compatibility confirmation, please provide the following details:

• Mating plug or receptacle part number and series
• Required pinout or wiring schematic
• Cable outside diameter and conductor size
• Electrical load (current and voltage per contact)
• Environmental conditions (temperature, humidity, exposure)
• Order quantity and target delivery date
