Introduction
Product Introduction: KAIDA MS27505E15B18SHN
1. Product Overview
As a high-reliability circular connector from KAIDA—a specialist in precision interconnect solutions for harsh-environment applications—the MS27505E15B18SHN is engineered to deliver stable, multi-channel electrical connections for complex systems in demanding industrial, aerospace, and defense scenarios. Designed in strict compliance with MIL-DTL-38999 (a global benchmark for rugged interconnects), this connector integrates robust mechanical construction with exceptional multi-contact electrical performance, making it ideal for applications where simultaneous transmission of power and signals is critical—such as avionics multi-sensor arrays, industrial control modules, and outdoor critical infrastructure with complex wiring needs.
2. Core Features
- Rugged Environmental Resilience: Built to withstand extreme operating conditions, including wide temperature fluctuations (-55°C to 125°C, optional -65°C to 150°C for extended use), high humidity (95% RH, non-condensing), intense vibration (up to 2000 Hz), and mechanical shock (up to 100 G). Equipped with SHN-series sealing (per configuration), it achieves IP67/IP68 protection to block dust, moisture, and liquid ingress—ensuring reliability in outdoor, industrial, or marine environments.
- Multi-Channel Electrical Precision: Features 18 gold-plated contact pins (reflected in the “18” in the model name), optimized for low contact resistance (≤ 5 mΩ initial, at 1 A, 25°C) and minimal signal loss. Each contact supports rated currents up to [XX] A (continuous) and rated voltages up to [XX] V AC/DC, enabling simultaneous transmission of multiple power lines and signal paths without cross-interference—critical for complex systems like aerospace navigation modules.
- Secure Bayonet Locking: Incorporates a MIL-DTL-38999-compliant bayonet-style locking mechanism for fast, tool-free mating (1/4-turn operation). The lock provides a vibration-resistant connection that prevents accidental disengagement, making it suitable for mobile applications (e.g., UAV telemetry, heavy machinery) where constant movement could compromise connections.
- Long-Term Durability: Constructed with high-wear materials—including anodized aluminum alloy housing (or flame-retardant thermoplastic) and gold-plated copper-alloy contacts (30 μin minimum thickness)—it supports ≥ 500 mating cycles without performance degradation. This longevity reduces maintenance frequency and replacement costs for long-deployment systems.
- Standardized Compatibility: Fully compatible with MS27505-series mating connectors, ensuring seamless integration with existing systems adhering to MIL-DTL-38999 or equivalent industrial standards. Its 15-size shell (marked by “15” in the model name) aligns with common compact interconnect footprints, simplifying retrofits and system expansions.

4. Application Scenarios
- Aerospace & Defense: Powers and connects multi-sensor systems in aircraft (e.g., engine monitoring sensors, navigation modules), UAV payloads (camera, telemetry, and control signals), and military ground equipment—withstanding extreme temperatures, vibration, and moisture during mission-critical operations.
- Industrial Automation: Integrates into complex manufacturing systems, such as robotic arms (controlling motors, encoders, and sensors) and factory control panels (transmitting power and data to multiple actuators)—resisting dust, oil, and mechanical shock in harsh production environments.
- Rail Transportation: Supports on-board electronics for trains, trams, and high-speed rail, including passenger information systems, braking control modules, and traction system sensors—simultaneously handling power and signal transmission while enduring vibration and temperature changes.
- Outdoor Critical Infrastructure: Connects multi-parameter monitoring equipment in renewable energy systems (solar inverters, wind turbine sensors), weather stations (temperature, pressure, and wind speed sensors), and telecom base stations (power supply and signal routing)—protected against rain, dust, and extreme weather.
- Marine Electronics: Used in shipboard integrated systems (navigation, communication, and propulsion control) and offshore platforms, withstanding saltwater corrosion, high humidity, and shock from waves while ensuring reliable multi-channel connectivity.
5. Design Highlights
- Optimized 18-Contact Layout: Contacts are arranged in a compact, interference-shielded pattern to minimize cross-talk between signal and power paths—critical for complex systems requiring simultaneous transmission of sensitive data and power.
- SHN-Series Enhanced Sealing: Multi-layer sealing (O-rings, grommets, and gasketed interfaces) tailored to the SHN specification provides robust IP67/IP68 protection, preventing liquid and dust ingress even in submerged or high-humidity environments.
- Lightweight, High-Strength Housing: Anodized aluminum alloy housing balances durability with low weight (critical for aerospace and UAV applications) while offering corrosion resistance for marine or industrial use.
- Anti-Misinsertion Polarization: Keyed shell and polarized contact alignment prevent incorrect mating, avoiding damage to the connector or connected equipment (e.g., industrial control modules or avionics sensors).
- Fast Field Installation: Bayonet locking enables one-handed, tool-free mating in seconds—reducing downtime during field maintenance or system assembly, even in tight spaces.
