Frequently Asked Questions
How many positions and what pitch does the LSHM-140-03.0-L-DV-A-N-K-TR have?
The LSHM-140-03.0-L-DV-A-N-K-TR is an 80-position connector with a 0.50mm pitch. This high-density configuration supports up to 80 signal or power contacts in a body length of approximately 0.972 inches, making it well suited for high pin-count board-to-board stacking applications in compact electronics.
What stacking height does this SAMTEC connector provide, and which board mounting method does it use?
This connector provides a 3.0mm board-to-board stacking height, which is specified in the part number suffix. It uses a peg board mounting option for reliable mechanical registration and stability. The 3.0mm stack height is compatible with slim embedded and telecom designs that require controlled inter-board spacing.
What contact finish is used on the LSHM-140-03.0-L-DV-A-N-K-TR mating contacts, and why does it matter for high-speed signals?
The mating contacts are finished with gold over nickel, providing excellent corrosion resistance and low contact resistance across the 80 pins. Gold plating is critical for high-speed signal integrity because it minimizes insertion loss and maintains consistent impedance even after multiple mating cycles, supporting reliable data transmission at multi-gigabit rates.
