Frequently Asked Questions
What is the contact pitch and position count of the LSHM-150-02.5-F-DV-A-S-K-TR?
The LSHM-150-02.5-F-DV-A-S-K-TR features a 2.5 mm pitch with 50 positions arranged in a dual-row configuration. This high-density layout provides 50 individual contact points across the connector body, which measures approximately 1.169 inches in length, making it suitable for compact board stacking applications.
Which industrial or embedded computing designs benefit most from the shielded construction of this SAMTEC board stacking connector?
Applications in industrial automation, ruggedized embedded computing, and telecommunications equipment benefit from the shielded construction of this connector. The shielding reduces EMI emissions and susceptibility at the interconnect level, and with 50 contacts at 2.5 mm pitch, it supports high pin-count board-to-board signal and power routing in electrically noisy environments.
How do the matte tin contacts with nickel barrier compare to gold-plated alternatives for long-term board stacking reliability?
Matte tin (Sn) contacts with nickel (Ni) barrier provide a cost-effective alternative to gold plating for lower-frequency mating cycles, typically rated up to 30 insertion cycles. The nickel barrier prevents tin migration into the copper base and maintains contact resistance below specified limits over the component's operating life, making it appropriate for permanent or infrequent-reconnect board stacking assemblies.
What is the factory lead time for the LSHM-150-02.5-F-DV-A-S-K-TR and how does the peg mounting option affect PCB layout?
The factory lead time for this part is 1 week, making it readily available for production schedules. The peg board mounting option adds mechanical retention posts to the connector body, requiring additional 0.8 mm to 1.0 mm diameter holes in the PCB layout to secure the connector and prevent misalignment during reflow soldering of the SMT contacts.
