4-Pin 5A Magnetic Pogo Pin Connector Male & Female Set with 15cm Cable

Specifications:

• Operating Voltage: Up to 24V 
• Operating Current: 5A (Maximum)
• Interface: 4-Pin (2 power/2 signal or 4 general purpose)
• Connector Type: Magnetic Spring-Loaded Pogo Pin (Male and Female set)
• Cable Length: 15cm (per side)
• Mounting Style: Free-hanging / inline cable
• Magnetic Configuration: Self-aligning with reverse polarity protection built-in 

Minimum hardware to get started:

• Soldering Iron & Solder : to securely connect the bare 15cm wire ends to your power source, PCB, or control board.
• Heat Shrink Tubing : to safely insulate your solder joints and prevent dangerous short circuits, which is critical when handling up to 5A of current.
• Power Supply / Battery Pack : to actually provide the power that will be transmitted across the magnetic coupling.

Safety Warnings:

• Current Draw Warning: This connector is rated for a maximum of 5A. Do not exceed this limit, and ensure the wires you splice into it are appropriately gauged (at least 22 AWG or thicker) to handle the load without melting.
• Debris Warning: The strong magnets can attract stray metal shavings, solder blobs, or screws on your workbench. Always wipe the connector faces clean before snapping them together to prevent bridging the power and ground pins.

Frequently Asked Question

• Is this connector compatible with Arduino and ESP32 projects? Yes, it works perfectly for supplying power or transmitting general digital signals to any microcontroller board.
• Can I use this to charge a lithium battery pack? Yes, provided your charging circuit and battery do not draw more than the maximum rated 5A.
• Does this work with standard 2.54mm pitch perfboards? The cables are free-hanging, so you can solder the bare wire ends directly to any perfboard, PCB, or wire harness.
• Can I connect multiple sets together? Each male connector is polarized with magnets to perfectly snap only to its paired female connector, preventing reverse polarity and mismatches.
• What is the maximum voltage this connector can handle? It is safely rated for use with standard DC voltages up to 24V.
• Can I run a continuous 5A current through it? Yes, the high-quality spring-loaded pins are designed to handle up to 5A continuously without overheating.
• Will I experience a voltage drop across the connector? The voltage drop is minimal due to the gold plating and strong magnetic tension keeping the pins firmly pressed together.
• Which pins should I use for power and ground? We recommend using the outer pins for VCC and GND to prevent accidental shorts if the connector is misaligned briefly during snapping.
• Do I need to solder the connections? Yes, the 15cm cables come with bare stripped ends that require soldering or crimping for a secure electrical connection to your circuit.
• How do I insulate the soldered wires? Always use properly sized heat shrink tubing over your individual wire solder joints to prevent accidental short circuits.
• Do I need a specific Arduino library to use this? No, this is a purely passive mechanical connector and does not require any software, code, or libraries to function.
• Can I send I2C or SPI signals through these pins? Yes, but keep the total cable lengths as short as possible to prevent signal degradation or interference on high-speed data buses.
• Will the magnetic field affect my sensor readings? The built-in magnets are highly localized, but you should keep them at least a few centimeters away from sensitive magnetometers or compass modules.
