METZ Connect MMT471A315 8-napainen PCB-liitinliitin, liitin, 3,5 mm jako, ruuviliitäntä, vihreä

The METZ Connect MMT471A315 stands out as a high-density PCB terminal block socket engineered for secure wire-to-board connections in compact industrial electronics. With an 8-pole configuration on a 3.5 mm pitch, it offers a space-saving solution without compromising on current capacity or reliability. Unlike standard terminal blocks, this socket features a horizontal wire entry and screw termination, allowing for straightforward wiring even in tight enclosures. Its green polyamide housing is not only visually distinct but also provides excellent insulation and mechanical stability, making it a preferred choice for automation, control systems, and power distribution boards.

Highlights

• 8 poles with 3.5 mm pitch for dense PCB layouts
• Rated for 10 A and 160 V (IEC) for robust power handling
• Accepts solid and stranded wires from 0.2 to 1.5 mm² (24–16 AWG)
• Horizontal wire entry simplifies routing in low-profile designs
• UL94 V-0 flammability rating ensures safety in demanding environments
• Wide operating temperature range from -40 °C to +105 °C

In daily use

Installation is straightforward: insert the stripped wire (5 mm) into the terminal opening, tighten the M2 screw to the recommended 0.2 Nm torque, and the connection is secure. The through-hole mounting provides strong mechanical anchoring to the PCB, reducing stress on solder joints during wire handling. The tin-plated copper alloy contacts deliver low contact resistance and excellent corrosion resistance, ensuring long-term performance. The green housing aids in visual identification and complements standard industrial color coding. Whether used in PLC interfaces, sensor connections, or power supplies, this terminal block delivers consistent and maintenance-free operation.
