Omnetics A28500-037 Nano-D 37-Pin Plug, Through-Hole Vertical

The Omnetics A28500-037 is a high-reliability, dual-row Nano-D plug connector designed for demanding aerospace, defense, and industrial applications. With 37 gold-plated male contacts, a rugged metal shell, and through-hole vertical terminations, it provides a compact, lightweight interconnect solution where performance and durability are critical.

Based on Omnetics Bi-Lobe^® Nano-D technology, this connector is capable of carrying up to 1 A per contact, while meeting stringent shock and vibration requirements. It is ideal for high-density PCB designs, avionics, satellite systems, and other mission-critical electronics.

Key Features

• 37-position Nano-D plug — dual-row, D-type Nano-D connector for high-density layouts.
• Male pins, vertical through-hole — straight tails for secure PCB soldering.
• Rugged metal shell — aluminum shell with nickel plating for strength and EMI performance.
• Gold-plated contacts — beryllium copper contacts with hard gold plating for low resistance and long life.
• 1 A per contact — suitable for low-power signal lines in harsh environments.
• Compact Nano-D footprint — 0.025" pitch with 0.040" row spacing for space-constrained PCBs.
• Mating hardware — designed for mating side male jackscrews (0-80) for secure retention.
