## Long description

The Phoenix Contact FK-MCP 1,5/ 4-ST-3,81 is a high-quality PCB plug-in connector engineered for reliable and efficient electrical connectivity in electronic assemblies. Featuring a 4-position design with a 3.81 mm pitch, this component ensures precise alignment and secure contact for circuit board applications. The connector utilizes a modern push-in spring connection method, which facilitates quick and tool-free wire insertion, significantly reducing assembly time while maintaining a robust mechanical and electrical bond.
Advantages
This connector offers exceptional reliability due to its high-quality tin-plated contact surface, which provides excellent conductivity and corrosion resistance. The push-in spring technology allows for rapid installation and reliable vibration-resistant connections, making it suitable for demanding industrial environments. Its compact design and standardized pitch ensure compatibility with a wide range of PCB layouts, while the durable construction supports consistent performance over long operational lifecycles.
Suitable for
Industrial control systems
Electronic device manufacturing
Circuit board prototyping and assembly
Signal and power transmission in automation equipment
When it may not be suitable
This connector is not intended for high-power applications exceeding its 8 A nominal current rating or 160 V voltage limit. It is also not suitable for environments where extreme temperatures or chemical exposure exceed the specified material tolerances of the connector housing.
Key specifications
Number of positions: 4
Pitch: 3.81 mm
Nominal current: 8 A
Rated voltage: 160 V
Nominal cross-section: 1.5 mm²
Connection method: Push-in spring connection
Contact surface: Tin
Color: Green
How to use
To use the connector, strip the wire to the appropriate length as specified by the technical requirements. Insert the solid or ferruled conductor directly into the push-in terminal point until it is fully seated. For stranded wires without ferrules, use a small screwdriver to actuate the spring mechanism before inserting the wire. Ensure the connection is secure by gently pulling on the wire. To remove the wire, actuate the spring release mechanism and pull the conductor out.
What to consider before purchase
Verify the pitch of your PCB layout matches the 3.81 mm specification.
Ensure the wire gauge used falls within the 0.14 to 1.5 mm² range.
Check that the total current and voltage requirements of your circuit do not exceed the connector ratings.
Confirm the number of positions required for your specific application.
Usage recommendations: Always ensure the power is disconnected before installing or removing connectors to prevent electrical hazards. Use appropriate wire stripping tools to avoid damaging the conductor strands.
