Molex Milli-Grid Series Shrouded Straight Through Hole PCB Header, 44 Contacts, 2 mm Pitch, 2 Row 87831-4420

Molex 87831-4420 Milli-Grid Series Shrouded Straight Through Hole PCB Header features 44 male contacts arranged in 2 rows with a precise 2 mm pitch, designed for high-density wire-to-board signal applications.

The connector system utilizes a 2.00 x 2.00 mm grid pattern to optimize board design flexibility while providing a shrouded construction that safeguards the contacts from physical damage during insertion and operation. It includes a centre polarization slot that ensures correct mating by interlocking with a key on the receptacle, preventing mismating. Additionally, centre or side locking windows offer a secure mechanical lock between the header and receptacle.

Its kinked solder tails assure reliable retention on the printed circuit board, and the locating pegs facilitate automatic insertion processes in manufacturing. The contacts are made from phosphor bronze and plated in gold, delivering excellent electrical conductivity and corrosion resistance. This PCB header supports through-hole mounting, providing strong mechanical stability.

Operating between -55°C and 105°C, this header is ideal for industrial and commercial equipment such as printers, fax machines, copiers, servers, routers, automotive audio and GPS devices, security systems, set-top boxes, and digital media players.

Part of the Molex 2.0 mm Milli-Grid Interconnection System, this product supports both board-to-board and cable-to-board connections with options for vertical or right-angle mounting. The robust design and versatile features make it suited for demanding electronic component assemblies.

High density 2.00 x 2.00 mm grid design ensures compact layout. Shrouded design protects contacts from damage. Centre polarization slot prevents mismating with secure locking windows. Kinked solder tails provide secure retention on PCB.
