The 4.20mm vertical dual row wafer connector DW-WF-242050 is a vertical through-hole power connector featuring a 4.20 mm pitch, brass tin-plated terminals, Nylon 66 UL94 V-0 housing and a 9 A / 600 V AC/DC rating. The supplied engineering configuration uses vertical 180° orientation, tin plating and tape-reel packaging.
4.20mm vertical dual row wafer connector DW-WF-242050WV02P-31TR-01 is a vertical through-hole PCB power connector designed for reliable wire-to-board electrical interconnection. The supplied Dragon Well engineering drawing identifies a 4.20 mm pitch, dual-row construction and 180° vertical orientation, with a polarized shrouded housing for controlled mating.
The connector is rated at 9 A AC/DC and 600 V AC/DC. Electrical performance includes 20 mΩ maximum contact resistance, 1000 MΩ minimum insulation resistance, and 1500 VAC per minute dielectric withstand voltage. The specified operating-temperature range is −25°C to +85°C.
The 4.20mm vertical dual row wafer connector uses brass terminals with tin plating. Its insulating housing is manufactured from Nylon 66 and is rated UL94 V-0 according to the supplied drawing. The combination of a shrouded housing, vertical mating direction and through-hole PCB termination makes the connector suitable for power-oriented board interfaces requiring secure mechanical PCB attachment.
For the supplied 02P engineering configuration, the drawing shows a body width of 5.40 mm, an overall body height of 12.85 ±0.30 mm, and a depth of 9.70 ±0.30 mm. The PCB terminal extension is specified at 3.40 ±0.35 mm. The recommended PCB footprint uses Ø1.40 mm holes with 5.50 mm center spacing.
The ordering code confirms WV vertical 180° orientation, 02P pin configuration, 31 tin plating, TR tape-reel packaging and series code 01.
This 4.20mm vertical dual row wafer connector is suited to power and wire-to-board PCB interconnection in electronic equipment where a 4.20 mm pitch, 9 A current rating and 600 V rating are required. Comparable 4.20 mm power connector systems from major connector manufacturers are also used for vertical through-hole wire-to-board power connections.
