MS5015 Connector Types, Configurations & Specifications

MS5015 Military Standard Connector for Industrial Robot Arms

For engineers building industrial robot arms, AGVs, or outdoor inspection platforms, the MS5015 series offers a MIL-DTL-5015 compliant circular connector family with 2 to 52 pins, bayonet locking, and an operating range of -55°C to +125°C. This page focuses on how to select the right configuration for your robotic system's power and signal needs.

Selecting the Right Pin Configuration

The MS5015 series supports 2 to 52 cores, with common configurations at 3, 4, 6, 8, 12, 19, 24, 37, and 52 pins. This range covers compact robot joint connections through complex control modules that need simultaneous power, signal, and data transfer. When choosing, consider the number of circuits you need today and whether future expansion is likely.

Environmental and Mechanical Performance

The anodized aluminum alloy housing resists corrosion and wear, while the IP67 rating protects against water ingress, dust, and debris. This makes the series suitable for outdoor inspection robots, rescue robots, and industrial robots in dusty or wet environments. The EMI shielding design helps maintain stable communication between robotic modules.

Installation and Maintenance Considerations

The bayonet locking mechanism secures the connection in approximately 3/4 of a turn, which supports fast installation and maintenance. The integrated keyway prevents misinsertion, protecting equipment during assembly. Gold-plated brass contacts provide a rated service life of at least 500 mating cycles, reducing replacement frequency in high-use applications.

Application Fit and Boundaries

The MS5015 series suits industrial robot arms, collaborative robots, AGVs/AMRs, outdoor inspection robots, and special-purpose rescue robots. However, confirm that your specific voltage, current, and cable diameter requirements fall within the rated values before specifying. For applications requiring higher pin counts or different environmental ratings, verify the exact shell size and insert arrangement against your system drawing.

Key Decision Points for Buyers

• Pin count and layout: Match the number of cores and contact arrangement to your power, signal, and data circuits.
• Gender and mounting: Determine whether you need male or female contacts and cable or panel mounting for each side of the connection.
• Environmental exposure: Verify that IP67 and the -55°C to +125°C range cover your operating environment, including any washdown or outdoor conditions.
• Mating cycles: For high-cycle applications, confirm that the 500-cycle rating meets your maintenance schedule.
• Locking preference: Bayonet locking suits quick connect/disconnect; confirm this matches your installation access and vibration requirements.

Specification Interpretation

The temperature range of -55°C to +125°C defines the operating limits for the connector assembly. The housing material is aluminum alloy, contacts are brass plated with gold, and the insulator uses PPS/PEI. These material choices support the stated environmental and mechanical performance. For detailed electrical ratings, refer to the Technical Specifications section on this page.

When This Connector Is Not the Best Fit

Consider alternatives if your application requires more than 52 pins, needs a different locking mechanism such as screw coupling, or demands a higher ingress protection rating than IP67. For applications with extreme vibration beyond the MIL-DTL-5015 test profile, verify the specific test levels against your system requirements before selection.

Information to Include in Your Inquiry

To receive an accurate quotation and configuration recommendation, prepare the following details:

• Required pin count and contact arrangement
• Gender for each side (plug and receptacle)
• Mounting style: cable, panel, or PCB
• Cable outer diameter and conductor size
• Operating voltage and current per contact
• Environmental conditions: temperature, moisture, dust exposure
• Mating cycle frequency and locking preference
