<h2>Male connector/plug <i>WINSTA</i>® MIDI 3-pole</h2><br/><br/>The <i>WINSTA</i>® MIDI male connector/plug B coding saves space and money and space thanks to its compact dimensions. The pluggable PCB connectors with spring pressure connection technology and Push-in CAGE CLAMP® technology from WAGO permit maintenance free terminal connections. The coding options reduce installation errors, allowing fast, secure wiring of all components. B coding enables the <i>WINSTA</i>® MIDI pcb connectors to be used for control in applications in automation, robotics, and mechanical engineering. This pcb connectors is used for electrical currents up to 25 A. Thus the product is ideally suitable for high power loads. The <i>WINSTA</i>® MIDI Pluggable Connection System with Push-in CAGE CLAMP® spring pressure connection technology facilitates precise electrification. Due to the integrated test slot, connections can be checked even when they are plugged in. This saves time, labor, and money.<br/><br/><h3><i>WINSTA</i>® MIDI solutions for your electrical installation – protected against mismating and maintenance-free</h3><br/><br/>The WINSTA® Pluggable Connection System allows pluggable electrical installation. This significantly reduces the need for servicing and lowers costs. Take advantage of the pluggable version of our maintenance-free spring pressure connection technology too!
