JST XA Series Straight Surface PCB Header, 7 Contact, 2.5 mm Pitch, 1 Row, Shrouded BM07B-XASS-TF (LF)(SN)

The JST BM07B-XASS-TF (LF)(SN) XA Series Straight Surface PCB Header is a high-quality wire-to-board connector designed for industrial and electronic applications requiring robust and reliable PCB connections. Featuring 7 male contacts arranged in a single straight row with a 2.5 mm pitch, this shrouded header ensures secure mated connections, optimized for durability and ease of assembly.

The connector housing is manufactured from glass filled PA66 nylon, an engineering plastic that prevents solder cracking and offers excellent mechanical stability under thermal cycling. Designed with an integrated locking ramp device, the header firmly secures the mating connector, reducing the risk of vibration-induced disconnection common in industrial, automotive, and manufacturing environments.

Additional design features include insertion guides and polarization bosses, which enable easy and accurate positioning on the PCB during assembly processes, minimizing errors and improving throughput.

The contact pins utilize a copper alloy base with tin plating, offering low electrical resistance and excellent corrosion resistance for long-term reliability. Rounded pins are reflow treated to provide low insertion force, enhancing compatibility with automated assembly techniques and reducing wear on mating connectors.

Operational specifications include a rated current of 3 amperes and voltage withstand up to 250 volts, suitable for a wide range of electronic boards and control systems. The connector supports surface mount assembly, making it compatible with modern PCB manufacturing.

The shrouded design protects contacts and prevents misalignment during assembly. Locking device secures the connection under vibration and mechanical strain. Glass filled PA66 nylon housing mitigates solder cracking issues.

Low insertion force pins speed up assembly and ensure longevity. Rated for 3A current and 250V voltage for versatile electronic applications. Operating temperature range from -25°C to 85°C suits varied environments. Polarization bosses ensure correct orientation and reduce assembly errors.

Copper alloy contacts with tin plating offer excellent conductivity.

This JST XA Series PCB header is widely used in industrial electronics, automation controls, instrumentation, and power distribution modules where reliable wire-to-board connections are critical. Its robust design and quality materials provide long service life in demanding operational conditions.
