Why This M8 PCB Panel Mount Connector?
Choosing the right M8 PCB panel mount connector means evaluating IP rating, pin count, orientation, and long-term reliability. Our connectors are designed with industrial-grade materials — gold-plated contacts, nickel-plated brass shells, and FKM sealing rings — ensuring thousands of reliable connections in the harshest environments. The IP67 rating (IEC 60529) guarantees full dust protection and water submersion up to 1 meter for 30 minutes.
For technical questions about M8 connector wiring, coding, or custom pin configurations, refer to the IPC-A-620 quality standards for cable and wire harness assemblies.
Frequently Asked Questions
What is an M8 PCB panel mount connector?
An M8 PCB panel mount connector is an 8mm circular industrial connector with threaded coupling that mounts directly to a printed circuit board. It provides IP67 waterproof and dustproof sealing for reliable power and signal transmission in harsh industrial environments.
What is the difference between M8 and M12 connectors?
M8 connectors have an 8mm thread diameter and are more compact, ideal for space-constrained sensor applications. M12 connectors (12mm thread) support higher pin counts up to 17 pins and higher power ratings. Our M12 PCB mount connector series provides additional options for larger systems.
Is the M8 connector IP67 rated?
Yes. All our M8 PCB panel mount connectors feature IP67 protection with FKM sealing rings. They are fully dust-tight and withstand temporary water immersion up to 1 meter depth for 30 minutes per the IEC 60529 standard.
What is the difference between straight and right-angle M8 PCB connectors?
Straight connectors have pins perpendicular to the PCB surface for vertical mounting. Right-angle connectors have pins parallel to the PCB, reducing overall height by 40-60%, ideal for slim enclosures and limited-clearance applications.
What pin configurations are available?
This M8 PCB panel mount connector is available in 3, 4, 5, 6, and 8-pin configurations. Current ratings range from 1.5A to 3A and voltages from 30V to 60V depending on pin count.
