Frequently Asked Questions
What are the vibration and mechanical shock ratings of this 15-pin MIL-Spec D-Sub connector?
This 15-pin MIL-Spec connector is engineered for high-stress environments, rated for sinusoidal vibration from 10 Hz to 2000 Hz at 196 m/s², random vibration with a Power Spectral Density (PSD) of 0.4 G²/Hz (23.1 G RMS overall acceleration), and mechanical shock up to 735 m/s² for 11 ms.
What are the mounting dimensions and hardware options for panel or chassis installation?
The connector features a 23.6mm overall width and an 18.22 ± 0.10mm center-to-center mounting pitch. It is supplied with 2xM2 locking jackscrews for secure mating retention, and provides two Ø2.3mm mounting holes when configured without the locking assembly.
What are the electrical performance limits and operating temperature range for this 15P pre-wired assembly?
Each contact supports a 3A rated current with a contact resistance of less than 10 mΩ, a minimum insulation resistance of 5,000 MΩ, and an 800V dielectric withstanding voltage. The assembly operates reliably from -55°C to +125°C across a rated mechanical life of 500 mating cycles.
Can the pre-wired flying lead length (Dimension L) be customized for specific harness layouts?
Yes, Dimension L represents the pre-terminated wire lead length in millimeters (mm) and is fully customizable according to customer BOM and routing specifications.
Overview and Application Notes
This 15-Pin MIL-Spec D-Sub (Micro-D) pre-wired connector assembly is engineered for high-reliability interconnect applications subject to extreme shock, random vibration, and wide thermal fluctuations. Featuring a compact 23.6mm overall shell width with an 18.22mm mounting hole center-to-center pitch and dual M2 locking jackscrews, it provides a secure, space-saving interface for aerospace, defense, industrial automation, and ruggedized embedded systems. Each connector comes factory-terminated with customizable wire lead lengths (L) to streamline system integration and harness routing.
