Frequently Asked Questions
What is the total pin count and pitch of the Harwin M50-3612542, and how are positions arranged?
The Harwin M50-3612542 provides 50 positions arranged as 25+25 in a dual-in-line (DIL) layout with a 1.27 mm pitch. The body measures 1.25 inches in length, accommodating 50 individual contacts suitable for parallel bus, mixed signal, or power and ground routing in embedded systems and industrial control boards.
How does the peg board mounting option on the M50-3612542 benefit PCB assembly processes?
The peg board mounting feature on the M50-3612542 provides mechanical registration to the PCB before and during reflow soldering, preventing connector movement or misalignment during the SMT process. This is especially valuable on high-density boards with 50-position connectors where even minor misalignment of 1.27 mm pitch contacts can cause bridging or open joints in automated assembly lines.
When is the M50-3612542 a better procurement option than a 0.100" pitch DIL connector for the same 50-position requirement?
The M50-3612542 at 1.27 mm pitch offers a significantly smaller footprint than a standard 0.100" (2.54 mm) pitch DIL connector for the same 50-position count. At 2.54 mm pitch, a 25-position single-row connector spans 63.5 mm, while M50-3612542's dual-row 1.27 mm pitch fits 50 positions in a 1.25 inch (31.75 mm) body, making it the right choice when board space savings of 50% or more are required.
