Harwin M300 High Reliability Connectors
Harwin M300 Series High Reliability Connectors are 3mm pitch interconnects designed for high-reliability power delivery and feature gold-plated beryllium copper contacts with a four-finger design to ensure consistent electrical performance. These connectors incorporate stainless steel jackscrews for secure mating, shrouding, and polarization for proper alignment and offer through-board or crimp termination options. The M300 series high reliability connectors operate within a temperature range from -65°C to +175°C and withstand 1000 mating cycles. Typically used in aerospace, defense, industrial, and other harsh environments.

Every day you can count on the sun rising in the east. That almost matches the level of dependability you get with Harwin’s M300 series high reliability connectors. Supporting over 1000 mating cycles, the M300 series has a maximum working voltage of 600Vac/dc, a maximum current load of 10A per contact, and a maximum contact resistance of 6mΩ. With an operating temperature from -65°C to +175°C, this connector is going to work in just about any environment, and its ability to handle 100G shock and 10G vibration at up to 9 hours means that this connector is the one that you can truly rely upon. To make connections easy, its shrouded and polarized designs prevents mis-mating, and its UL94V-0 flame-retardant rating means that it is suitable for many applications including aerospace, defense, industry, and automotive.
