Business Wire
Stewart Connector, a division of Bel Fuse Inc. (NASDAQ:
BELFA) (NASDAQ: BELFB), today announced the availability of
the modular MRJ21® interconnect system under a license agreement
with Tyco Electronics. The MRJ21 cabling system is designed to
promote optimal port density in space-constrained telecom and
premise wiring applications. The Category 5e cable assemblies
simultaneously support VoIP (Voice over Internet), PoE (Power over
Ethernet) and GbE (Gigabit Ethernet) while offering installers the
ability to connect 24 twisted pairs (12 two-pair or 6 four-pair
ports) with just one connection. These Input/Output (I/O)
interconnect systems’ double-blade design allows up to 4 times the
port density of traditional 2x6 stacked modular jacks (RJ45), and
up to 3 times the port density of an RJ21 connector. Devices are
available in four connection schemes including six unshielded RJ45
connectors to 45-degree angle MRJ21 connectors, six unshielded RJ45
connectors to straight MRJ21 connector, straight MRJ21 connector to
straight MRJ21 connector, and straight MRJ21 connector to 45-degree
angle MRJ21 connector. The MRJ21 board-mount receptacle boasts a
robust board lock design for superior PCB strain relief, and the
cable assemblies provide offset jackscrews to ensure positive
latching and secure cable retention. Assemblies are durability
tested to 500 cycles.
Stewart Connector’s MRJ21 cabling system targets
telecommunication and premise wiring applications wherever
traditional stacked modular jacks and RJ21 connectors are used.
They may be confidently employed in applications including network
closets, core and edge routers, digital cross connects, GbE
switches, 10/100BASE-T, and DSLAM. The assemblies allow a
connection migration path from such legacy products as punchdown
blocks, modular plug breakouts, and standard RJ21 assemblies, and
are designed with a die-cast backshells for shielded
applications.
Fully shielded to reduce EMI emissions, the high-performance
modules’ differentially paired footprint and contact layout further
reduce crosstalk through built-in compensation. Connectors feature
1 mm pair spacing and 1.5 mm pair-to-pair spacing. Additionally,
the dual-row receptacles meet the height requirements of the
CompactPCI™ specification.
Average pricing for Stewart Connector’s MRJ21 cable assemblies
is $145.00 each. Delivery is from stock to 4 weeks. Custom assembly
lengths are accommodated.
