The APC Electronic MP-6P4C is a modular RJ-12 plug designed for telephony and data networking cabling. These connectors feature a 6P4C configuration, meaning they have six positions with four active contacts to ensure reliable signal transmission. Constructed with a clear plastic housing, the plugs allow you to visually verify the wire placement during installation, while the gold-plated contacts prevent corrosion and maintain a stable connection over time. This pack of 100 pieces is a practical choice for technicians or network installers who need to create custom-length telephone cables or repair existing communication lines.
