3. M50 Connectors – 1.27mm pitch Male and Female Connectors Introduced as Standard product in 1997/1998 Sales on this product range has steadily increased throughout this period More variations now available across the industry Why more M50?

4. Additional M50s and New M52s To enhance the range of Fine Pitch products, additional connectors were specified for the 2005 Catalogue launch. The new products encompass 1.27mm pitch products, with a choice of 1.27mm or 2.54mm row spacing. SIL and DIL versions are available. There is now greater flexibility in connector heights and the choice of whether to have location pegs on SMT products. The M52 range increases the choice of Fine Pitch connectors, and gives Harwin more products meeting current industry standards. The addition of Pin Header Variant options for the M50 range give the ultimate flexibility in board-to-board connections. This has also been introduced for the M52 range. Why more M50?

M50-3XX additions mate with current M50-3XX items – basic pin headers and sockets. M50-4X0 additions (shrouded single polarisation) do not mate with current M50-4X2 items (shrouded double polarisation). Breakdown of Connectors
