PT06E-8-4PSR Circular Connector Overview

The PT06E-8-4P(SR) is a 4-pin circular connector engineered for demanding aerospace, defense, and industrial applications. Its aluminum alloy shell and high-temperature thermoset insulation support reliable electrical connections in harsh operating environments.

This connector uses solder terminations with strain relief (SR), offers IP67-rated protection, and operates across a temperature range of -55°C to +200°C. The 4-pin layout provides secure power or signal transmission for critical electronic systems.

Key Selection Considerations

  • MIL-DTL-5015 compliance: Rugged construction suited to military and aerospace specifications.
  • Material durability: High-temperature, corrosion-resistant housing and contacts for extended service life.
  • Strain relief termination: Solder connections with SR reduce mechanical stress on wires during vibration.
  • Application fit: Suitable for aerospace, defense, and industrial electronics requiring IP67 protection.

Application Boundaries

This connector is appropriate for systems that require a compact 4-pin interface, high-temperature tolerance, and protection against dust and water ingress. It is not intended for high-density pin counts or applications requiring quick-disconnect bayonet coupling; confirm your mating plug or receptacle configuration before ordering.

Configuration and Mating Guidance

Verify the mating receptacle series, pinout arrangement, and cable outside diameter before purchase. For solder termination, confirm conductor size and prepare cable ends according to the recommended stripping dimensions. Provide your application drawing or pinout when requesting a quote to ensure correct matching.

Inquiry Checklist

When contacting us, include the following details to expedite selection:

  • Mating connector series and gender required
  • Pinout or wiring diagram
  • Cable outside diameter and conductor size
  • Operating temperature and environmental exposure
  • Required quantity and delivery timeline

For related circular connector options, review the 12G Series Circular Connectors or consult the PT06A MIL-DTL-26482 Circular Connector Aluminum Alloy Plug for additional configuration details.
