Frequently Asked Questions

What contact configuration and pitch spacing does the SDL-120-G-19 provide for board interconnection?

The SDL-120-G-19 provides 40 socket positions arranged in a double-row configuration with 0.100-inch (2.54 mm) center-to-center pitch, using beryllium copper contacts with gold (30 µm) plating over nickel (50 µm) barrier layer, ensuring reliable signal transmission and mechanical durability across thousands of mating cycles.

How does the low-profile screw-machine socket design improve reliability in test and measurement equipment?

The SDL-120-G-19 low-profile screw-machine socket design reduces contact resistance while maintaining secure mechanical grip, making it ideal for 40-pin test equipment interfaces, instrumentation backplanes, and embedded expansion modules where repeatable connection integrity and low insertion force are essential for production and field deployment.

Is the SDL-120-G-19 compliant with RoHS and suitable for industrial automation applications?

Yes, the SDL-120-G-19 is fully lead-free with RoHS compliance and gold/nickel plating rated for thousands of mating cycles, making it suitable for industrial instrumentation, test equipment, and embedded systems requiring reliable 40-pin modular connections with long operational life and minimal maintenance.
