The Science of Connector Arcing: Understanding Inrush Current & Contact Bounce in Hot-Plug Scenarios
Apr 25, 2026A technical deep dive into how mechanical dynamics (e.g., micro-bounces during insertion) combined with capacitive loads trigger momentary high-current arcs — complete with oscilloscope waveform examples and mitigation tactics validated in MIL-STD-1344 and IEC 60512 test standards.

Why Do Connectors Spark During Mating? And How to Prevent Arcing Effectively
Apr 25, 2026This blog explains the physics behind sparking (arcing) when electrical connectors are mated under load, identifies key contributing factors like voltage, current, separation speed, and contact material, and provides practical, engineering-backed strategies to minimize or eliminate arcing — from derating and sequencing to arc-suppression circuits and contact plating selection.
