4 Pin Power Relimate Male Connector Straight 2.54mm Pitch: A Detailed Look

The 4 Pin Power Relimate Male Connector Straight 2.54mm Pitch is a widely used connector in electronics, particularly for hobbyists, makers, and industrial applications. This small but versatile component provides a reliable and convenient way to connect electronic devices and circuits. Let’s delve deeper into its details:

Description:

• Type: 4 Pin Male Relimate Connector (often referred to as JST-XH)
• Form Factor: Straight
• Pin Count: 4
• Pitch: 2.54mm (0.1 inch) – This refers to the distance between the centerlines of adjacent pins.

The connector consists of two parts:

1. Housing: A plastic housing that holds the metal pins securely.
2. Pins: Four male pins made of conductive metal (usually brass or copper) that establish the electrical connection.

The male connector features pins that protrude outwards, designed to mate with a corresponding female connector that has sockets to accept the pins. The 2.54mm pitch ensures consistent spacing and alignment for easy and reliable connections.

Specifications:

• Current Rating: Typically 3 Amps (although this can vary depending on the manufacturer)
• Voltage Rating: Typically 250 Volts (similar to current rating, this can vary)
• Operating Temperature: -25°C to 85°C
• Wire Gauge: Usually compatible with 22 AWG to 28 AWG wires (American Wire Gauge)

Features:

• Compact size: Ideal for applications where space is limited.
• Easy to use: Straightforward assembly with soldering or crimping techniques.
• Polarized design: Prevents incorrect connection due to a specific orientation of the housing. This is a crucial safety feature to avoid damaging circuits.
• Versatility: Compatible with various electronic components and DIY projects.
• Low cost: An affordable solution for connecting circuits.

Applications:

• Power Supply Connections: Commonly used for connecting power supplies to electronic devices like Arduino boards, Raspberry Pi, and other development boards.
• Sensor Connections: Enables easy connection of sensors like temperature sensors, light sensors, and pressure sensors to data acquisition systems or microcontrollers.
• LCD and Display Connections: Provides a reliable connection between LCD screens and driver boards.
• Battery Connections: Can be used to connect batteries to circuits for portable applications.
• Internal Board Connections: Useful for connecting different modules within a larger electronic device.
• DIY Electronics Projects: A staple component for hobbyists and makers due to its ease of use and versatility in various electronic projects.

Developments:

The basic design of the 4 Pin Relimate connector has remained consistent for many years, proving its effectiveness and reliability. However, there have been some advancements in related technologies:

• Micro JST Connectors: Smaller versions of the JST connector family cater to applications requiring even tighter spacing and miniaturization.
• Locking Relimate Connectors: These variants incorporate a locking mechanism for more secure connections in environments with vibrations or movement.
• SMD (Surface Mount Device) Relimate Connectors: These connectors are designed for surface mounting on PCBs (Printed Circuit Boards) using soldering techniques, offering a more compact and efficient solution.

Selection Considerations:

When choosing a 4 Pin Relimate Male Connector, consider the following factors:

• Current and Voltage Requirements: Ensure the chosen connector meets the current and voltage demands of your application.
• Wire Gauge: Select a connector compatible with the wire gauge you plan to use.
• Cable Length: Decide if you need pre-wired connectors with attached cables or prefer to solder or crimp your own wires.
• Mounting Style: Choose through-hole mounting for soldering onto PCBs or pre-crimped options for direct connection.

Conclusion:

The 4 Pin Power Relimate Male Connector Straight 2.54mm Pitch is a fundamental building block in the world of electronics. Its compact size, ease of use, affordability, and reliable connections make it a popular choice for various applications. With its consistent design and ongoing advancements in related connector technologies, the Relimate connector family is likely to remain a mainstay for electronics enthusiasts and professionals alike.
