Glenair Mighty Mouse (Series 80) Connectors

Glenair’s Mighty Mouse Series 80 is the leading miniature connector series used in military, civil and ground applications. It mimics the MIL-DTL-38999, however, it is smaller in size and lighter. The Series 80 Mighty Mouse Connector is ideal for the extensive range of power and signal applications that rely on safe environmental and mechanical performance and electromagnetic compatibility as well as high-speed applications such as gigabit Ethernet. This series offers six different coupling variations-size #23 crimp contacts are standard, set on .076″ centers. Mighty Mouse connectors have been used in many critical military and civil applications specializing in harsh and rugged environments. Considering this series is half the size and weight of the standard D38999 connectors, many engineers switched their designs toward this series.

The goal of creating this series was to drastically decrease the size and weight of this flight critical connector while maintaining its core performance features. The connector reduction work took place in three critical areas beginning with reduction of the shell size and the addition of banding and shrink boot accessory functions. By doing so, Glenair successfully managed to cut not only the size and weight of the D38999, but also reduce the cost significantly.
