Frequently Asked Questions
What are the body dimensions of the M22-7141742 connector and how do they affect PCB layout?
The M22-7141742 socket connector has a body length of 1.339 inches (34.01 mm), breadth of 0.157 inches (3.99 mm), and depth of 0.173 inches (4.39 mm). These compact dimensions allow the connector to be placed on standard PCB footprints in multi-row board assemblies without excessive keep-out zones, enabling high-density interconnect designs in embedded systems and compact industrial controllers.
What contact finish does the M22-7141742 use, and how does it benefit long-term connection reliability?
The M22-7141742 uses a tin (Sn) plating over a nickel (Ni) barrier layer on its termination contacts. The nickel barrier prevents tin diffusion into the copper base material, maintaining contact resistance below 20 mΩ over thousands of mating cycles. This finish is well-suited for applications with moderate mating frequency, such as board replacement in test jigs and field-serviceable embedded modules operating at 5 V to 48 V supply rails.
In which industrial or embedded applications is the M22-7141742 socket connector most commonly specified?
The M22-7141742 is frequently specified for board-to-board interconnects in industrial control modules, sensor interface cards, and robotics joint controllers that require RoHS-compliant, mechanically secure connections. Its 1.339-inch body length accommodates multi-pin signal buses in a single connector, reducing the number of separate connectors needed in designs with 10 to 40 signal lines. Medical monitoring devices and portable test instruments also use this connector for its low profile and reliable mating in space-constrained enclosures.
How does the M22-7141742 compare to a standard 2.54 mm pitch header when selecting a board connector for a compact design?
Compared to a standard 2.54 mm pitch header, the M22-7141742 Harwin socket provides a more secure socket-style locking engagement that resists accidental unmating under vibration levels up to several g in industrial environments. While both share similar pitch options, the Harwin M22 series socket features nickel-barrier contact construction for lower long-term contact resistance compared to bare tin headers, which is important for signal integrity in 3.3 V and 5 V logic bus applications with contact currents in the 1 A to 3 A per-pin range.
