The 10090769-P444ALF is a 44-pin D-SUB male connector with solder bucket termination designed for high-reliability interconnect applications. It features a rated voltage of 250V and rated current of 2.5A, with contact resistance of 25 mO maximum initially and 40 mO maximum after mating cycles. The connector operates over a temperature range of -55°C to +105°C and provides a dielectric strength of 750V RMS, with an insulation resistance of 5000 MO minimum at 500V DC. The gold-flash contact finish ensures reliable mating with a minimum of 50 mating/unmating cycles, and the insertion/extraction force per contact is 5N maximum with 0.2N minimum. This connector is ideal for industrial control systems, telecommunications equipment, and data acquisition systems requiring robust, multi-pin interconnections.
