The 09031646921, also identified as 09 03 164 6921, is a DIN 41612 Type C male PCB connector from HARTING with the official designation DIN-Signal C064MS-3,0C1-2. It provides 64 angled male contacts for motherboard-to-daughtercard, extender-card and PCB-to-cable applications.
The 64 active contacts are arranged in rows a and c at positions 1 through 32. Contact spacing is 2.54mm on both the mating and termination sides. The connector uses wave-solder termination and includes a fixing flange for secure PCB mounting.
Electrical specifications include a 2A rated current at 20°C, 20mΩ contact resistance, insulation resistance greater than 10¹²Ω, and a 1kVrms test voltage. Both minimum clearance and creepage distance are 1.2mm. The connector meets Performance Level 2 according to IEC 60603-2.
The contacts are made from copper alloy, with Au over NiP over Ni on the mating side and Sn over Ni on the termination side. The insert is glass-fiber-filled thermoplastic resin in RAL 7032 pebble grey and meets UL 94 V-0 flammability requirements. Mechanical endurance is rated at 400 mating cycles.
The connector has a limiting temperature range of -55°C to +125°C and does not support hot plugging. It is RoHS and ELV compliant and carries relevant UL and CSA approvals. HARTING specifies a packaging quantity of 100 pieces and a net weight of approximately 12.54g per connector.
