JST JWPF Series Vertical PCB Header, 4 Contacts, 2 mm Pitch, Shrouded, Wire-to-Board, Fibreglass B04B-JWPF-SK-R (LF)(SN)

JST B04B-JWPF-SK-R (LF)(SN) Vertical PCB Header is a high-performance wire-to-board connector designed for demanding environments requiring waterproof capabilities. This model features a shrouded housing made from fibreglass reinforced polybutylene terephthalate (PBT), providing superior mechanical strength and efficient electrical insulation.

Its precise 2 mm pitch ensures compatibility with a wide range of PCB layouts, enabling accurate and reliable connections in electronic assemblies. The header supports up to four copper alloy contacts, each plated in tin to enhance conductivity and resist corrosion, making it ideal for industrial, automotive, and harsh environmental electronics.

This connector carries up to 3A of current and withstands voltages up to 100V, facilitating robust signal and power transfer within PCB systems. Exceptional ingress protection rated to JIS C0920 grade 7, achieved via solid rubber seals and contained seal rings, ensures its suitability for applications where moisture, dust, and adverse conditions are prevalent.

The single-row configuration simplifies board design and assembly, while the vertical orientation aids in reducing PCB footprint and optimizing component placement. Crimp contacts and a secure inner housing lock mechanism further ensure strong retention and stable connectivity, eliminating risk of unintentional disconnection during operation.

Operating across a wide temperature range, from -25°C to 85°C, this header is engineered to maintain integrity and performance in both low and high-temperature working environments. Its tail pin length of 3.3 mm and wire-to-board mounting support flexible integration into various industrial, embedded, and consumer electronics.

Common industrial applications include automotive control units, outdoor instrumentation, HVAC controllers, power distribution boards, and waterproof sensor modules. The header’s enhanced sealing and spring construction make it highly reliable in laboratories, manufacturing sites, and commercial equipment exposed to water or dust.

Whether for new PCB development or for upgrading reliability in existing systems, the JST JWPF Series Vertical PCB Header delivers proved durability, waterproofing, and electrical performance.
