Frequently Asked Questions
How many positions and rows does SMH-120-02-T-S provide, and what is its pin pitch?
The SMH-120-02-T-S is a 40-position, dual-row socket connector on a 0.100 inch (2.54 mm) pitch, with 20 positions per row. This arrangement supports up to 40 independent signal connections and is compatible with standard 0.100 inch dual-row headers and pin strips widely used in embedded and industrial PCB designs.
What contact finish does SMH-120-02-T-S use, and how does it compare to gold-plated alternatives?
The mating contacts of SMH-120-02-T-S use matte tin over nickel (50 microinch nickel barrier), while the termination contacts use tin over nickel as well. Tin plating is cost-effective for applications with lower mating cycle counts, while gold plating is preferred for hundreds of cycles. Tin-finished sockets are standard in industrial and prototyping applications with infrequent connector swaps.
Why choose through-hole mounting for SMH-120-02-T-S in high-vibration or field-serviceable PCB designs?
Through-hole mounting on SMH-120-02-T-S produces solder joints that penetrate the PCB, providing mechanical pull-out strength significantly higher than SMT pads. This makes the 40-position connector suitable for industrial equipment, test fixtures, and field-replaceable modules where repeated insertion and removal, mechanical shock, or vibration could lift SMT solder joints over time.
Is SMH-120-02-T-S RoHS and lead-free compliant for use in European markets?
Yes, SMH-120-02-T-S carries a Pb-free code designation and is suitable for lead-free PCB assembly using SnAgCu solder compatible with a 260°C peak reflow profile. This ensures compliance with RoHS directives required for sale and distribution in the European Union and other markets with lead-free mandates.
