General Specifications
The VA Connector from JST is a 7.92mm pitch, disconnectable crimp style connector, suitable for primary power supply circuits and various high-current applications. This connector is capable of handling a current rating of 7A AC, DC with an AWG #18 wire, and a voltage rating of 250V AC, DC. Designed for use within a temperature range of -25°C to +85°C, it also features good contact and insulation resistance levels. The connectors are applicable for a PC board thickness of 1.6mm and wire sizes ranging from AWG #20 to #18.
Design Features
Design aspects include an anti-misinsertion construction and a reliable locking mechanism, enhancing safety. Different models cater to top-entry and side-entry types, including options with a PCB stabilizer. These connectors, offering compactness and capacity, are provided with several standards certifications, such as UL Recognized E60389, Certified LR20812, and R75122.
Materials and Compliance
Materials include phosphor bronze with tin-plated contacts (reflow treatment) and PA plastic with a UL94V-0 rating for housings, ensuring robustness. All components are RoHS compliant, adhering to environmental regulations.
Mounting and Assembly Details
Mounting details provided are viewed from the soldering side, taking into account tolerances and the variety of PC board piercing methods. Appropriate machinery and tools such as the MK series crimper and applicator are recommended for crimping, with specific models for various connector types.
Marking and Packaging
Connectors and terminals are clearly marked, including labels for color identification. For instance, terminal model numbers like SVA-41T-P1.1, VAR-2, and series like B2P3-VH have designated quantity per reel or bag. Further information on color variants and ordering can be obtained by directly contacting JST.
Important Notes
Dimensions in the datasheet are guidelines and it’s advised to consult JST for detailed specifications. Furthermore, the datasheet instructs to refer to “General Instruction and Notice when using Terminals and Connectors” available at the end of the catalog for RoHS compliance details and other notices.
