M300 3.00mm Power Connectors

Harwin M300 3.00mm Power Connectors are a range of high-reliability, high-performance connectors for aerospace, defense, industrial, or other harsh environment applications. With a compact power connection of up to 10A per contact, the M300 connectors achieve a lightweight, robust solution with a proven track record under extreme conditions. Fitted stainless steel jackscrews guard against vibration and shock, while a four-finger contact design maintains electrical continuity. Low outgassing properties meet NASA requirements for vacuum or space usage. Harwin M300 3.00mm Power Connectors operate in a temperature range of -65°C to +175°C and withstand 1000 mating cycles.
