MS27505E17B35P MIL-Spec Connector for Aircraft Control Systems

MS27505E17B35P MIL-Spec Circular Connector Overview

The MS27505E17B35P is a MIL-Spec circular connector engineered for demanding aerospace and aviation systems. It delivers reliable electrical connections for aircraft control, avionics, and mission-critical equipment where consistent performance under harsh conditions is non-negotiable.

Key Selection Criteria for Aerospace Buyers

When evaluating this connector for your application, consider these verified decision points:

• Mating interface: Confirm the mating receptacle part number and shell size to ensure a proper fit with your existing wiring harness.
• Pin configuration: Verify the 35-pin layout and contact arrangement against your system's pinout drawing before ordering.
• Environmental sealing: Assess the IP rating and moisture resistance relative to your installation location—pressurized cabin versus unpressurized bay.
• Mechanical endurance: Review vibration tolerance and mating cycle ratings against your maintenance schedule and flight profile.

Application Fit and Installation Considerations

This connector suits aircraft electrical systems, avionics racks, and high-reliability ground support equipment. Its robust shell construction resists vibration, moisture ingress, and temperature extremes typical of aerospace environments.

For installation planning, verify the cable entry diameter and backshell compatibility with your specified wire gauge. Confirm whether your application requires a straight or right-angle configuration, and check that the coupling mechanism matches your access constraints.

Parameter Interpretation for Selection

The MS27505E17B35P designation indicates a specific shell size, insert arrangement, and contact gender. Before ordering, confirm the rated current per contact, voltage rating, and operating temperature range against your load requirements. These values determine whether this connector meets your signal integrity and power delivery needs.

Suitable and Unsuitable Applications

Suitable: Aircraft control systems, avionics signal transmission, and military ground equipment requiring MIL-Spec compliance and proven field reliability.

Unsuitable: Do not use this connector for high-current power distribution beyond its rated contact capacity, or in applications requiring frequent unmating under load. It is not designed for submersible or continuous underwater exposure.
