71-419748-08P

Overview

The Amphenol Aerospace Operations 71-419748-08P is a circular MIL-spec connector plug belonging to the PT series, designed for high-reliability interconnect applications. It features a bayonet coupling mechanism and an in-line orientation suitable for cable mounting. The component utilizes crimp termination for secure electrical connections and includes environmental sealing capabilities to withstand harsh operating conditions. Constructed with aluminum alloy housing and gold-plated contacts, it ensures durability and low contact resistance across a wide temperature range.

Feature Summary

• Bayonet locking mechanism provides rapid and secure mating
• Environmental sealing protects against moisture and contaminants
• Crimp termination ensures reliable signal and power transmission

Applications

• Aerospace avionics systems
• Military communication equipment
• Industrial instrumentation

Procurement Notes

Verify the specific shell size and contact arrangement against the official datasheet before procurement. Confirm that the ordering suffix matches the required plating and seal configuration. Ensure compatibility with existing panel or cable mounting requirements. Check for any updated revision levels or alternate source approvals required by your supply chain standards.

Selection Notes

Select this model when a robust MIL-DTL-26482 Series I connector is required for critical environments. Evaluate the need for bayonet coupling speed versus screw-lock alternatives. Consider the aluminum housing weight benefits against corrosion resistance needs. Verify that the crimp tooling and contact kits are available for maintenance purposes.

Part Context

This part belongs to the Amphenol PT series of miniature cylindrical connectors, widely used in defense and aerospace sectors. The series is known for its compact design and high density. The 71- prefix indicates a manufacturer-specific designation within the broader MIL-DTL-26482 standard framework, ensuring interoperability with other compliant components.

Replacement Considerations

Compatible substitutes include MS3120E20-41S and MS3106E20-41S, provided the pin/socket polarity and environmental sealing ratings match the original design requirements. Verify that the replacement maintains the same bayonet coupling interface and cable entry orientation.
