Frequently Asked Questions
How does the 1.27 mm pitch of the M52-5102045 compare to standard 2.54 mm pitch sockets for high-density PCB designs?
At 1.27 mm (0.05 inch) pitch, the M52-5102045 provides double the contact density of standard 2.54 mm pitch sockets, fitting 40 contacts (20+20) in a board length of roughly 25.4 mm versus 50 mm for an equivalent 2.54 mm alternative. This density advantage is critical for small form-factor modules in UAVs, wearables, and compact embedded systems.
What is the benefit of the 4.6 mm body height of the M52-5102045 in stacked PCB assemblies?
The 4.6 mm vertical height allows socketed modules to sit close to the host board, maintaining a low overall stack height under 10 mm when a standard module is inserted. In space-constrained enclosures for industrial IoT gateways or embedded vision systems, this low-profile through-board socket saves several millimeters versus taller 7 mm or 8.5 mm alternatives.
When should engineers choose gold over tin contact finish for the M52-5102045 socket in a mission-critical application?
Gold contact finish is preferred over tin when the M52-5102045 will experience more than 50 insertion cycles, operate in humid or corrosive environments, or carry low-level signals below 100 mV where oxide-induced contact resistance increase would cause measurement errors. Gold plating maintains contact resistance below 20 mΩ throughout the connector's rated insertion life.
Which types of plug-in modules or mezzanine cards is the M52-5102045 socket designed to receive?
The M52-5102045 accepts standard 1.27 mm pitch DIL pin headers from compatible Harwin M52 series and similar 0.05 inch pitch mezzanine modules, including small compute-on-modules, RF front-end cards, and sensor daughtercards with 40 pins. The 1.016 inch body length accommodates 20 pins per row across the 0.197 inch body width.
