What are the key features of M50-3602542R?

  • 1.27 mm (0.05 inch) pitch dual-in-line layout with 50 contacts (25+25) enabling high-density SMT board-to-board or board-to-module connectivity in compact designs
  • Selective gold and tin contact finish providing reliable low-resistance mating at the contact interface with cost-effective tin termination on the PCB pads
  • Tape and Reel packaging supporting high-volume automated SMT pick-and-place assembly with a low-profile body of only 0.066 inch depth

What is M50-3602542R used for?

The M50-3602542R is ideal for compact embedded modules, IoT sensor boards, and SOM (System-on-Module) carrier cards where a 1.27 mm pitch 50-position dual-in-line SMT header provides reliable board-to-board signal connectivity in space-constrained designs. Its low-profile 0.066 inch body depth minimizes stack height in densely populated PCBs used in medical wearables, industrial gateways, and portable test instruments. The Tape and Reel packaging supports seamless integration into high-volume automated SMT assembly lines.

Frequently Asked Questions

How many contacts does the M50-3602542R provide and what pitch does it use?

The M50-3602542R provides 50 contacts arranged in a dual-in-line (DIL) configuration of 25+25 positions at a 1.27 mm (0.05 inch) pitch, offering a compact high-density footprint of 1.25 inch body length for SMT board-to-board or module interconnects in embedded and IoT applications.

What contact plating does the M50-3602542R use and how does it affect mating performance?

The M50-3602542R uses selective gold plating on mating contact surfaces over a nickel barrier, combined with tin on the PCB termination side, providing low contact resistance and reliable electrical performance across 50 positions through multiple insertion cycles while keeping material cost lower than fully gold-plated alternatives.

For which types of PCB assembly processes is the M50-3602542R best suited?

The M50-3602542R is optimized for SMT reflow soldering processes and arrives in Tape and Reel packaging for automated pick-and-place machinery, making it ideal for high-volume production of IoT modules, embedded computing boards, and wearable devices where a 50-position 1.27 mm pitch low-profile connector must be placed and reflowed at high throughput with a body depth of only 0.066 inch.

When is the Harwin M50-3602542R preferred over a through-hole pin header for board-to-board connections?

The M50-3602542R is preferred over through-hole headers when PCB thickness constraints, double-sided component placement, or SMT-only manufacturing lines are involved, since its 0.066 inch SMT body depth and 1.27 mm pitch allow a 50-position dual-row connector to be surface-mounted on densely packed boards without drilling holes or using wave soldering.
