Field Terminated M Series S66™ Blocks
The S66M1-50 is fully compatible with all industry standard accessories while providing a proven, economical solution for terminating high performance cable. The wide range of mounting accessories allows the S66M1-50 to be installed in almost any environment. Each pair of S66™ clips has been moved slightly closer together, creating additional space between conductors of adjacent pairs and reducing near-end crosstalk.
