About

JST 3.5mm BH Series Connectors — Robust Wire-to-Board Interconnects for Power & Signal The JST BH series at 3.5mm pitch occupies the ideal middle ground between compact signal connectors and heavy-duty power interconnects. Engineered for applications requiring reliable current handling in a moderate-density PCB footprint, the BH series is widely deployed in industrial control systems, power electronics, motor drive assemblies, and embedded computing platforms where both mechanical robustness and electrical performance are non-negotiable. Key Technical Advantages 3.5mm Balanced Pitch: Provides a practical balance between connector density and current capacity (up to 5A per contact), making the BH series suitable for mixed power-and-signal harness assemblies where a single connector family must handle diverse circuit requirements. Positive-Latch Retention: Secure snap-fit housing mechanism resists accidental unmating under vibration, shock, and repeated connect/disconnect cycles, ensuring long-term reliability in field-deployed industrial and consumer equipment. High-Temperature PA66 Housing: UL94 V-0 rated nylon housing rated for continuous operation up to 105°C, maintaining structural integrity and dielectric performance across thermal cycling environments typical of power electronics enclosures. Tin-Plated Copper Alloy Contacts: Delivers stable, low contact resistance with excellent resistance to fretting corrosion and oxidation over extended service life in thermally and mechanically demanding installations. Versatile Pin Count Range: Available from 2-pin to 12-pin configurations, accommodating simple power rails through multi-channel control and sensor wiring harnesses within a single connector family. Wire Gauge Compatibility: Accepts 20–26 AWG wire, compatible with standard BH-series crimp tooling for consistent, production-ready terminations across a broad range of wire sizes. RoHS & REACH Compliant: All materials meet current EU environmental directiv
