Frequently Asked Questions
How many positions does the M20-9994045 support and what is the pin pitch?
The M20-9994045 provides 40 positions in a single-in-line (SIL) arrangement with a 2.54 mm pitch, resulting in a total body length of 4 inches. This makes it well suited for parallel bus connections, GPIO breakouts, and multi-signal wire harnesses requiring 40 circuits on a standard pitch grid.
What is the pin length and contact finish of the M20-9994045 and why does it matter for solder joints?
The M20-9994045 has a 6.1 mm pin length below the PCB surface with gold (Au) contact finish on the termination side. The 6.1 mm length ensures adequate solder joint formation during wave soldering while gold plating reduces oxidation and improves wettability, producing reliable through-hole connections in industrial PCB assemblies.
Can the M20-9994045 be trimmed or split for shorter position counts in prototyping applications?
The M20-9994045 is a 40-position SIL connector with a 2.54 mm pitch that can be mechanically cut at the body to yield shorter segments for prototyping use, as is standard practice for breakaway headers. Each cut segment retains 2.54 mm pin spacing, making it compatible with standard breadboards, IDC sockets, and 0.1-inch pitch PCB footprints.
