Frequently Asked Questions
What pitch and pin count does the Harwin M50-3612542R use?
The M50-3612542R is a 50-position dual-in-line connector arranged as 25 contacts per row on a 1.27 mm (0.05 inch) pitch. This fine pitch allows mounting within a 31.75 mm body length, making it suitable for dense PCB layouts in compact embedded systems and portable instruments.
How do the mounting pegs of M50-3612542R improve assembly reliability?
The integrated PCB mounting pegs align the connector on the board during placement and resist lateral movement through the 260 °C reflow soldering process. This mechanical support prevents tombstoning and connector shift, ensuring consistent solder joint quality across all 50 SMT contact positions in high-volume production.
Which application scenarios benefit most from the M50-3612542R low-profile design?
Its low-profile SMT body, rated body depth of 1.68 mm, suits stacked PCB assemblies in compact industrial controllers, data acquisition modules, and handheld test equipment where vertical clearance is below 5 mm. The 50-position density also reduces the number of discrete connectors needed, simplifying wiring harness design.
Is the M50-3612542R RoHS compliant and available for automated assembly?
Yes, the M50-3612542R carries a Pb-free (RoHS compliant) designation and ships in tape-and-reel format suitable for automated pick-and-place machines. Each reel provides a continuous supply for SMT lines, supporting production volumes requiring uninterrupted feeder loading without manual connector handling.
