Samtec ST4 Series Straight Surface PCB Header, 100 Contacts, 0.4 mm Pitch, 2 Row, Shrouded ST4-50-1.50-L-D-P-TR

Samtec ST4-50-1.50-L-D-P-TR is a new high-performance straight surface mount PCB header designed for reliable board-to-board connections in advanced electronic assemblies. This connector features 100 male contacts arranged in two rows with a fine pitch of 0.4 mm, enabling compact and precise mating interfaces.

The housing material is a durable black Liquid Crystal Polymer (LCP) that provides outstanding electrical insulation and mechanical stability over a broad operating temperature range from -55°C to +125°C. Contacts are made from phosphor bronze for strength and conductivity, plated with silver and tin to resist corrosion and ensure good electrical contact.

The connector supports a current rating of 1.6A per pin, with the capability to power two pins simultaneously, making it suitable for high-speed and high-current signal transmission. The shrouded design ensures secure and protected mating, reducing the risk of damage or misalignment in industrial or commercial electronics.

Its narrow pitch and reliable contacts make it ideal for dense electronic applications such as telecommunications equipment, computing devices, instrumentation, and industrial automation systems.
