Samtec Straight Surface PCB Header, 80 Contacts, 0.5mm Pitch, Dual Row, Shrouded LSHM-140-03.0-L-DV-A-N-K-TR

Samtec LSHM-140-03.0-L-DV-A-N-K-TR is a high-speed, high-density, surface mount PCB header connector featuring 80 contacts in a dual row arrangement, with a fine 0.5mm pitch. Specifically engineered for robust board-to-board connectivity in demanding industrial and electronics environments, this component provides developers and OEMs the benefits of reliable signal integrity and design flexibility.

The header employs gold-plated phosphor bronze contacts that ensure excellent conductivity, long-term resistance to corrosion, and sustained durability even in high-cycle applications. Its housing is constructed from liquid crystal polymer, which delivers mechanical strength, dimensional stability, and the ability to withstand elevated reflow soldering temperatures.

80-pin contact arrangement and high-speed data transmission capability (up to 23 Gbit/s for vertical mounting configurations) make it suitable for modern high-bandwidth electronic circuits.

Its hermaphroditic, self-mating design reduces inventory cost and provides options for vertical, right angle, or reverse mounting to optimize layout and stack height from 5mm to 12mm.

Each contact incorporates an undercut retention notch, resulting in increased mating/unmating force and an audible click to confirm a secure connection. The board-to-board system supports parallel, perpendicular, and coplanar system designs, fitting a wide variety of industrial, communications, and instrumentation needs.

The shrouded structure offers robust mechanical protection against mismating and environmental factors. Surface mount termination streamlines automated assembly processes and ensures strong PCB attachment.

Applications include high-speed computing, control panels, measurement instrumentation, network equipment, and advanced industrial automation systems requiring dependable, compact internal interconnections. The component’s wide operating temperature range from -55°C to +125°C supports deployment in challenging environmental conditions.
