Self-Strip Terminal Connectors
R66M Series & Category 5 Non-Connectorized

R66M150XR66M Series & Category 5 Non-Connectorized

R66M series non-connectorized quick-clip blocks are manufactured of UL Listed 94 V-0 rated material and are designed for fast and easy termination of insulated solid copper wire.

The R66M series has a clip capacity of 50 horizontal rows by 4 vertical rows. Unskinned 20- through 26-gauge conductors or skinned 18- and 19-gauge conductors can be easily terminated using the industry standard R714B punch-down tool.

The R66M series blocks are supplied with integral fanning strips, molded on each side of the block, and notched every ten rows for easy identification. The blocks are available mounted in gray or beige molded impact-resistant plastic housings.

The Category 5 R66M150 blocks comply with EIA/TIA-568 Category 5 specifications. These blocks provide the highest transmission performance for speeds up to 100 megahertz per second, while decreasing attenuation, near-end crosstalk, and return loss.

Category 5 blocks use the same sturdy block as the standard R66M series. For high speed performance EIA/TIA-568 recognizes only 24- gauge UTP (unshielded twisted pair) horizontal wiring. Category 5 gives a network increased flexibility and improved performance.

Features & Benefits

  • Sturdy block—for easy installation
  • Designed block stackability—allows high pair density
  • Impact-resistant molded housings—provide long life; low maintenance costs
  • Notched fanning strip—for ease of wire tracing, identification, and good housekeeping
  • UL Listed and meets EIA/TIA-568 Category 5 specifications—to exceed documented performance levels; conforms to state-of-the-art LAN systems for high speed data
  • Category 5 provides network flexibility—to handle emerging voice and data applications
  • Category 5 supports data rates up to 100 megahertz per second—for network flexibility

Application

R66M series blocks are used in equipment rooms to cross-connect key telephone and PBX systems. The blocks terminate 25 twisted pair station cable and have cross-connect features from key service units to station equipment. These blocks are also used to connect a private branch exchange to its stations. The compact size and convenience of quick-clips on the R66M series have expanded its use on all types of customer premises and central office equipment, including T1 and data connections.

The Category 5 series give users the ability to support virtually all data and voice applications conforming to the level of wiring used with the 5 series blocks support the most advanced applications such as FDDI over copper, and other high speed applications. The Category 5 series blocks with Level 4 wiring support data up to 20 megahertz for token ring or equivalent applications, and with Level 3 wiring, the block supports data up to 16 megahertz for T2 equivalent applications.
