Frequently Asked Questions
What contact finish does the M40-3202045R use, and how does it affect connector reliability?
The M40-3202045R uses a gold (Au) contact finish on its termination contacts, which provides excellent corrosion resistance and maintains low contact resistance typically below 20 mΩ even after hundreds of mating cycles. Gold plating is preferred in low-current signal connectors where surface oxidation on base metals would cause intermittent connections in precision measurement and embedded module applications.
How does the peg board mounting option on the M40-3202045R improve mechanical stability on PCBs?
The integral mounting peg on the M40-3202045R locks into a drilled through-hole on the PCB, providing a mechanical anchor that resists connector pull-out forces and mating side loads during insertion. This is especially valuable in industrial and automotive applications where vibration and repeated mating cycles can loosen surface-only solder joints on a 0.787 inch body receptacle.
What board space does the M40-3202045R occupy, and is it suitable for compact PCB designs?
The M40-3202045R body measures 0.787 inch (approximately 20 mm) in length and 0.126 inch (approximately 3.2 mm) in breadth, occupying a narrow footprint on the PCB. This slim profile makes it suitable for compact embedded computing boards and industrial I/O modules where row connectors must fit within tight board area budgets alongside other components.
Is the M40-3202045R compliant with RoHS and REACH regulations for export to EU markets?
Yes, the M40-3202045R is explicitly marked as RoHS-compliant with a Pb-free code and carries the REACH compliance designation, making it fully eligible for export to EU markets and for use in designs requiring halogen-free and lead-free material declarations. Gold-finished contacts further ensure the connector meets environmental and material reporting requirements in industrial and medical connector supply chains.
