Samtec LSHM Series Straight Surface PCB Header, 80 Contacts, 0.5 mm Pitch, 2 Row, Shrouded LSHM-140-02.5-L-DV-A-S-K-TR

The Samtec LSHM-140-02.5-L-DV-A-S-K-TR is a high-performance straight surface PCB header designed for compact board-to-board connections in demanding electronic environments. This model features 80 contact points, arranged in two rows with a narrow 0.5 mm pitch, ensuring that it meets the requirements for high-density designs.

Each contact is constructed from gold-plated phosphor bronze, delivering reliable electrical performance and excellent corrosion resistance. The shrouded housing, made from Liquid Crystal Polymer, provides robust mechanical protection while maintaining a slim profile for space-constrained PCB layouts. The surface-mount orientation enables compatibility with automated SMD processes, streamlining assembly and integration.

The LSHM series Razor Beam connector incorporates a hermaphroditic terminal/socket strip, offering audible feedback on mating. Mating and unmating forces are approximately four to six times greater than conventional micro pitch connectors, providing secure mechanical connectivity even under vibration or movement. The system supports parallel, perpendicular, and coplanar board-to-board interfaces, and a shield option is available for applications requiring EMI protection.

This connector supports a maximum current of 2A and a voltage rating of 160V AC, making it suitable for both signal and low-power applications. It operates reliably in environments ranging from -55°C up to 125°C, ensuring performance across a wide spectrum of temperature conditions. Solder termination with male contacts further simplifies integration into standard PCB manufacturing processes.

Applications include industrial control boards, high-speed signal transfer, telecommunications equipment, laboratory electronics, and commercial products requiring robust board-to-board connections. The self-mating hermaphroditic design can help reduce inventory costs and streamline product sourcing.

In summary, the Samtec LSHM-140-02.5-L-DV-A-S-K-TR is ideal for designers and engineers seeking a secure, high-density option for reliable and durable PCB connectivity.
