Overview of EH CONNECTOR 2.5mm Pitch
The datasheet provides detailed information about the EH CONNECTOR, which features a 2.5mm pitch and is designed for disconnectable crimp style connections. This compact connector is optimal for high-density internal wire-to-board connections, offering both affordability and reliability. The device is described as having a low profile of 8.1mm post-mounting and a width of 3.8mm, positioning it as an ideal component for space-constrained applications.
Electrical and Mechanical Specifications
The connector has a current rating of 3A AC/DC for AWG #22 wires and a voltage rating of 250V AC/DC. It operates within a temperature range of -25°C to +85°C, accommodating temperature rise during current application. The initial contact resistance is specified at 10mΩ max, increasing to a maximum of 20mΩ after environmental testing. An insulation resistance of at least 1,000MΩ, along with an 800V AC/minute withstanding voltage, ensures durable performance and reliability.
Applicability and Compliance
The EH CONNECTOR can be used with an array of wire sizes ranging from AWG #32 to #22, accommodating various applications. Printed circuit board (PCB) thickness requirements are between 0.8 to 1.6 mm. Moreover, the connector is RoHS compliant for environmental standards. However, users are encouraged to consult the “General Instruction and Notice when using Terminals and Connectors” section of the catalogue for more information, or to contact JST directly for specific details.
Design and Features
Key features of the EH CONNECTOR include a slim design, highly reliable contacts, polarizing guides, and simple yet effective crimping processes. Standards by which the connector is recognized or certified include UL Recognized E60389, Certified LR20812, and CSA Standard R50082349.
Materials and Options
Components like contacts and housings are made from materials such as phosphor bronze with a tin-plated finish for enduring connectivity; these components also undergo a reflow treatment to boost reliability. For gold-plated products or low-insertion force type contacts designed with vibration resistance in mind, JST should be contacted for details.
Dimensions and Packaging
Dimensions are provided for the housings and shrouded headers, with varying quantities per bag or box indicating bulk packaging options. The circuit numbers for these components range from 2 to 15, with post-material being brass coated in copper and tin, and housing material specified as PA 66, UL94V-0 in natural white color. Alternative color codes for identification and corresponding part numbers are offered as well.
Additional Components and Tools
JST also details the necessary crimping tools and applicators, designed explicitly for the EH CONNECTOR series. These tools include dies and applicator models compatible with the contacts which facilitate the crimping process, ensuring secure and efficient connections.
This datasheet is designed to provide comprehensive information about the EH CONNECTOR series for potential users or buyers, noting that further details or variations such as customization options can be obtained by contacting JST directly.
