MS3116F18-32PN Military-Spec Circular Plug, 32 Contacts, Aluminum Shell,

Product Specification

1. Core Functions

• Dual-Purpose Transmission: Enables simultaneous transmission of power (for high-current loads) and signals (control, data, or communication signals), supporting integrated system connectivity without multiple separate connectors.
• Military-Grade Environmental Resistance: Withstands extreme temperatures (typically -55°C to +125°C), and features excellent resistance to moisture, dust, oil, and chemical exposure. It also resists vibration (per MIL-STD-202) and shock, ensuring stable performance in harsh conditions.
• Secure Bayonet Locking: Uses a bayonet-style locking mechanism for fast, tool-free mating and unmating. This design provides a tight, anti-loosening connection that prevents accidental disengagement, even under high mechanical stress.
• Corrosion & Wear Protection: Constructed with high-grade materials—including a zinc-plated or cadmium-plated steel shell and gold-plated copper alloy contacts. These materials deliver strong corrosion resistance and low contact resistance, extending the connector’s service life.
• Standardized Compatibility: Complies with MIL-DTL-5015, ensuring interchangeability with other connectors of the same standard. This allows easy replacement and integration across military, aerospace, and industrial systems.

2. Typical Applications

• Aerospace & Defense: Used in military aircraft (avionics systems, engine control units), ground combat vehicles (communication radios, weapon system controls), and naval vessels (shipboard power distribution, radar systems), where reliability in extreme conditions is critical.
• Heavy-Duty Industrial Machinery: Deployed in construction equipment (excavator hydraulic controls, bulldozer electrical systems), mining machinery (sensor arrays, power supplies), and offshore oil drilling equipment, enduring vibration, dust, and fluid exposure.
• Transportation (Rugged Sectors): Applied in rail transit (train traction control systems, onboard communication modules) and commercial aviation ground support equipment, adapting to frequent vibration and temperature fluctuations.
• Test & Measurement (High-Reliability): Integrated into military equipment testers, aerospace component validation tools, and field-deployed measurement devices, ensuring stable signal/power transmission during on-site or lab testing.
• Emergency & Field Equipment: Used in military field hospitals (portable medical devices, power inverters) and emergency rescue gear (tactical communication systems, portable lighting), withstanding harsh outdoor conditions.
