METZ MMT471A115 PCB-bus, 4-polig, 3,5 mm rastermaat, groen

PCB terminal blocks often fail when connections are cramped, difficult to solder, or unable to handle the required current in industrial control systems. The METZ MMT471A115 PCB socket solves these challenges with a compact 3.5 mm pitch and a robust 4-pole design, ensuring reliable, space-saving connections on printed circuit boards. Its through-hole mounting and solder termination provide a secure mechanical and electrical bond, while the green polyamide housing offers clear identification and durability in demanding environments.

Who is it for

This PCB socket is ideal for electronics engineers, PCB designers, and technicians working on industrial automation, building control, or embedded systems. It suits applications requiring a dependable board-to-wire interface with moderate current capacity, such as sensor connections, control panels, and power distribution on PCBs.

Tips

For reliable soldering, preheat the PCB and use a soldering iron with a fine tip to avoid overheating the polyamide housing. Ensure the wire is stripped to the correct length and fully inserted before soldering to prevent loose connections. When designing your PCB, leave adequate clearance around the socket for easy wire access and future maintenance.
