METZ Connect MMT371A115 PCB Socket 4-Pole 3.81mm Pitch Screw Terminal Green

Connecting wires to a printed circuit board often means choosing between a secure hold and easy servicing. The METZ Connect MMT371A115 PCB socket solves this by combining a screw terminal connection with through-hole mounting, giving you a reliable, vibration-resistant link that can be disconnected and reconnected whenever needed. With a 3.81 mm pitch and 4 poles, it fits compact PCB layouts while handling up to 8 A and 160 V.

Who is it for

This socket is built for engineers, technicians, and hobbyists working on industrial controls, automation systems, or custom electronics. It suits anyone who needs a durable board-level connector that can be wired in the field without special tools. Whether you are prototyping a new design or maintaining existing equipment, the MMT371A115 offers a straightforward solution.

Main features
