The 09052486831 from HARTING, also identified as 09 05 248 6831, is a DIN 41612 Type E female board-to-board connector with the official designation DIN-Power E048FS-4,5C1-2. It uses 48 straight female contacts and is designed for motherboard-to-daughtercard and mezzanine connections.
The connector uses wave-solder termination with a 4.5mm termination length and includes a fixing flange for PCB retention. Its 48 contacts are arranged across rows a, c and e at even-numbered positions from 2 through 32. Contact spacing is 5.08mm on both the mating and termination sides.
Electrical specifications include a 6A rated current at 20°C, maximum contact resistance of 15mΩ, insulation resistance greater than 10¹²Ω, and a 1.55kVrms test voltage. Clearance and creepage distances are both 3mm.
The contacts are made from copper alloy, with noble metal over nickel on the mating side and tin over nickel on the termination side. The insert is glass-fiber-filled thermoplastic resin in RAL 7032 pebble grey, with a UL 94 V-0 flammability rating. The connector meets Performance Level 2 according to IEC 60603-2 and is rated for at least 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 UL 1977 and CSA-C22.2 No.182.3 approvals. HARTING specifies a packaging quantity of 20 pieces and a net weight of approximately 16.68g per connector.
