JST Male Connector 2.54mm (3-Pin) (Straight / Right Angle)

JST Male Connector 2.54mm (3-Pin) Overview

The JST Male Connector 2.54mm (3-Pin) is a compact, reliable wire-to-board connector designed for secure electrical connections in electronics projects. With a standard 2.54mm pitch and three contacts, it reliably carries power, ground and signal lines in a small footprint for hobbyist and commercial applications.

Straight and Right-Angle Variants

Choose between straight and right-angle mounting depending on board layout and space constraints:

• Straight: Ideal for vertical header mounting on PCBs where cables connect from above.
• Right-Angle: Perfect for edge connections or horizontal routing to keep wiring neat in compact enclosures.

Key Features

• Type: JST male connector (wire-to-board)
• Pin count: 3-pin for power, ground and signal
• Pitch: 2.54mm (standard spacing compatible with many headers and perfboards)
• Construction: Durable plastic housing with corrosion-resistant metal contacts
• Compact and lightweight design for tight spaces
• Secure mating and reliable electrical contact for long service life

Specifications

• Connector family: JST
• Contact material: Tin or nickel-plated metal (corrosion-resistant)
• Housing material: High-quality plastic
• Mounting styles: Through-hole or surface mount variants available depending on model
• Typical uses: PCB headers, wiring harnesses, and custom cable assemblies

Applications

This 2.54mm 3-pin JST male connector is widely used across electronics projects and products, including:

• Arduino shields and breadboard prototyping
• Robotics and automation systems
• RC models, drones and battery connections
• Sensors, modules and small embedded systems
• Custom wiring harnesses and repair work

Installation and Compatibility Tips

• Verify the mating female housing or PCB footprint matches a 2.54mm pitch and 3-pin layout.
• Use the straight variant for vertical connections; use the right-angle variant for edge or horizontal routing.
• Crimp or solder wires according to recommended practices to ensure reliable contact and strain relief.
• Inspect contacts for secure fit and avoid excessive force when mating connectors.
