M1-50 Field-Terminated Series S66 Block, 50-Pair

The M1-50 50-Pair S66 Wiring Block is a high-performance telecommunications and data connectivity solution designed for organized cable termination in commercial, residential, and enterprise network installations. Featuring a 50-pair capacity and a durable thermoplastic construction, this connector block provides reliable wire management and termination for compatible voice and data cabling systems.

Designed for Category 5e applications, the M1-50 supports compatible Voice over IP (VoIP) and Gigabit Ethernet (1000BASE-T) installations when used as part of a properly designed and tested cabling system.

The block accommodates 22–26 AWG solid insulated conductors or 18–19 AWG solid stripped conductors, offering flexibility for different telecommunications wiring requirements.

Integrated fanning strips help organize horizontal cabling and cross-connect jumper wires while providing a dedicated surface for circuit identification labels. This design simplifies cable routing, maintenance, and troubleshooting in structured wiring installations.

Manufactured from high-impact, flame-retardant thermoplastic, the M1-50 is designed for durable performance in professional telecommunications environments. Its Category 5e S66-style contact clip configuration supports consistent electrical connections and repeated installation handling.

The block is compatible with industry-standard S66 accessories and can be mounted on compatible S89-series stand-off brackets to provide additional cable routing space behind the terminal block.

Ideal for telephone systems, network distribution points, telecommunications closets, commercial buildings, and structured cabling installations, the M1-50 provides a cost-effective solution for managing multiple copper cable terminations.
