Video Transcript

Compact, lightweight, and probably the only thing left if a mythical dragon torches your lab. This describes Harwin’s M300 connector series. The 3.00 millimeter pitch connectors use a proven 4-finger beryllium copper contact design that ensures connectivity under high vibration and shock and enables operation up to 175 degrees celsius.

The contacts have a 10 amp current rating, and connectors are available in 3-contact single row and 6 or 10-contact dual row configurations, with variants for board-to-board or wire-to-board connections. The connector housing has an extended rear potting wall for additional strain relief, a jackscrew security system, and polarizing keyways to prevent mismating. Housings are manufactured from environmentally friendly materials and have very low outgassing. Harwin M300 connectors are rated for 1000 operations and have scoop-proof female contacts to prevent damage while mating.
