Horizontal 90° Dual Port 8P8C RJ45 Female Connector QR2120A-2SPB712EF, 100Mbps Fast Ethernet Integrated Transformer Filter Magnetics, DIP PCB Twin Network Jack with Per-Port Link Activity Dual LED
QITDA model QR2120A-2SPB712EF is a horizontal 90° DIP twin dual-port shielded RJ45 integrated connector designed for 100Mbps fast ethernet. Each independent port is pre-installed with dedicated fast ethernet pulse transformer, EMI filter magnetics and separate green-yellow dual LED indicators for real-time link & data activity feedback. It fully complies with IEEE802.3 100BASE-TX standard and backward compatible with 10BASE-T 10Mbps network.
Two fully isolated 8P8C RJ45 channels are combined into one nickel-plated metal shield housing, which saves much PCB layout space compared to two single-port sockets. The built-in magnetic ring and transformer module effectively suppress high-frequency crosstalk, signal attenuation, return loss and electromagnetic interference, ensuring stable lossless 100Mbps signal transmission for each port. Dual LED operation: solid green = successful physical link, flickering yellow = ongoing data transmission.
Horizontal right-angle DIP pin structure is fully compatible with automatic wave soldering mass production lines. Full nickel-plated metal shielding shell provides reliable EMI isolation between two twin ports and external noise environments, performing steadily in small switches, POS terminals, intercom systems, surveillance auxiliary boards and low-speed industrial network equipment. All contact terminals adopt phosphor bronze substrate with heavy gold plating, featuring ultra-low contact resistance, excellent abrasion resistance, anti-oxidation and long plug cycle service life.
This horizontal dual 100Mbps RJ45 socket is widely applied to mini 2-port fast ethernet switches, POS payment equipment, building intercom hardware, security alarm panels, embedded low-speed communication modules and cost-sensitive small network terminals. Customization options include pin length adjustment, modified LED positions and customized pin assignments. The product meets ISO9001 quality system and RoHS environmental compliance standards.
