JST PSI Series Straight Through Hole PCB Header 2 Contacts 4 mm Pitch 1 Row Shrouded B02B-PSILE-A1(LF)(SN)

The JST B02B-PSILE-A1(LF)(SN) is a high-quality PSI Series straight through hole PCB header engineered for precision and durability in wire-to-board interconnect applications. With a 2 contact configuration and 4 mm pitch, this header offers secure and repeatable electrical connections in circuit board layouts.

Its fully shrouded single row housing supports safety and prevents accidental mismating or misalignment during assembly, aided by a positive locking mechanism. The male contacts are manufactured from copper alloy and finished with tin plating for excellent electrical conductivity and long-term corrosion resistance.

The body is constructed from fiberglass reinforced polybutylene terephthalate, providing robust mechanical integrity and resilience to the demands of repeated connections. The component is designed for straight through hole mounting, ensuring stable fixation to the PCB even in environments with vibrations or handling stress.

This PCB header is rated for up to 12 A current and 300 V voltage, suitable for diverse electronics, control panels, and instrumentation assemblies. It is engineered to operate effectively in temperatures ranging from -25°C to 85°C, making it compatible with challenging industrial, laboratory, and commercial conditions.

The single row, 2-pin arrangement and shrouded construction facilitate convenience in compact layouts, while PCB pegs incorporated into the housing aid in accurate positioning and provide extra stability on the board. The design includes color coding and keying notches to further reduce the risk of mismating, enhancing assembly reliability and safety.

Applications of this JST PSI Series PCB header include power distribution, industrial automation, signal interface boards, laboratory measurement devices, and general PCB interconnection in commercial systems. The connector is especially useful where robust locking and shrouding are needed to maintain consistent connections in demanding environments.

For professionals seeking reliable PCB connections, this header provides maximized safety, mechanical retention, and compatibility with automated assembly processes. Its compliance with high-current and voltage ratings also makes it ideal for both signal and power lines in your electronic assemblies.
