Frequently Asked Questions
What is the total pin count and pitch of the SFM-135-02-H-D-K-TR socket strip?
The SFM-135-02-H-D-K-TR is a 70-pin dual-row socket strip with .050" (1.27 mm) pitch, placing 35 contacts per row in a surface-mount footprint that maximizes signal density for compact board-to-board interconnect solutions in industrial and telecom PCB designs.
How does the keying option on the SFM-135-02-H-D-K-TR prevent mating errors during automated SMT assembly?
The K suffix adds a mechanical polarization key that physically prevents the 70-pin socket from mating in the incorrect orientation, reducing costly assembly rework in high-volume SMT production where automated pick-and-place handles hundreds of placements per hour at .050" pitch density.
What temperature range does the SFM-135-02-H-D-K-TR support for use in demanding environments?
The SFM-135-02-H-D-K-TR is rated for operating temperatures from -55°C to +125°C, making it well-suited for harsh industrial, military, and telecom environments. Its 70-pin surface-mount construction at .050" pitch withstands thermal cycling while maintaining reliable contact resistance across all positions.
