71-432191-03P

Overview

The 71-432191-03P is a circular MIL-spec connector plug manufactured by Amphenol Aerospace Operations. It belongs to the PT series and features a size 8 shell with three pin contacts. The component utilizes a threaded coupling mechanism for secure mating. Electrical specifications include a current rating of 13 A and an operating voltage up to 250 V AC. The connector provides IP67 environmental protection when mated and operates within a temperature range of –40°C to +125°C. It supports up to 500 mating cycles and employs crimp contact termination.

Feature Summary

• Engineered for demanding industrial environments requiring reliable multipole connections
• Features a lightweight plastic shell combined with a durable metal coupling system
• Incorporates a triple-start ACME coupling thread for fast and secure mating

Applications

• Industrial machinery connectivity
• Factory automation systems
• Equipment exposed to moisture, vibration, and fluctuating temperatures

Procurement Notes

Verify the specific part number against official Amphenol documentation to confirm compatibility with existing mating connectors. Ensure that the required contact configuration matches the application's signal or power distribution needs. Confirm that the environmental sealing requirements align with the IP67 rating provided for the mated state. Cross-reference the thermal and electrical ratings with the operational parameters of the target equipment to ensure safe and reliable performance under all expected conditions.

Selection Notes

Select this component when a rugged, cost-effective solution is needed for harsh industrial settings without the weight of full metal-shell connectors. Consider the 13 A current rating and 250 V AC voltage limit for suitability in power and signal applications. Evaluate the need for serviceable contact-retention systems to simplify assembly and maintenance processes. Assess the requirement for repeated connection cycles, as the design supports up to 500 mating operations while maintaining performance integrity.

Part Context

This connector is part of the UPT Series portfolio expanded by Amphenol Industrial Operations. The series focuses on providing lightweight and rugged interconnect solutions for industrial equipment. The introduction of new configurations, such as the 12-pin variant, highlights the manufacturer's effort to offer flexible options for integrating power and signal connections. This specific model represents a compact circular design suitable for demanding operational environments.
