Specifications & Parameters

This 2.8 mm pitch 2×5P 5G base station connector is a highdensity boardtoboard / boardtocable interconnect component specially engineered for 5G communication infrastructure hardware. With a total overall length of 9.9 mm, this dualrow 4position perrow connector delivers compact footprint, stable signal transmission and outstanding mechanical reliability for base station internal wiring, power distribution and highspeed signal routing. It is widely deployed inside remote radio units, baseband processing units and auxiliary control modules of 5G macrosites and smallcell sites.

The mechanical dimension of total length 9.9 mm is strictly controlled during injection molding and stamping production. The 2.8 mm pin pitch balances highdensity layout and sufficient creepage distance, which is critical for 5G telecom equipment. The PPS housing offers excellent thermal stability, antiaging performance and resistance to chemical solvent inside base station cabinet environment. Selective gold plating is applied on the mating contact surface to guarantee lowresistance signal transmission even after longterm vibration and temperature cycling. The solder tails are tinned to achieve good solderability for PCB assembly. All raw material batches are traceable for telecomgrade quality requirement. Every finished connector undergoes dimensional inspection, plating thickness verification and electrical performance test before packing.

Product Features & Advantages

• Ultracompact dimension optimized for 5G base station internal space constraint With total length only 9.9 mm and 2.8 mm pitch 2×5P layout, this connector saves valuable PCB real estate inside densely packed 5G RU, BBU and smallcell cabinets. Modern 5G base station hardware integrates multiband radio modules, power supply circuits and signal processing circuits in limited cabinet volume. Miniaturized interconnect components become essential. This 9.9 mm shortbody design avoids physical interference with surrounding components, supporting compact PCB layout design without sacrificing electrical safety margin. Design engineers can implement dense harness routing while keeping enough clearance for thermal dissipation.
• Highreliability contact system for telecom longterm operation The contact spring is stamped from highelastic copper alloy. The mating contact area adopts precise selective gold plating process. Gold plating effectively prevents oxidation and surface corrosion under variable temperature and humidity inside outdoor base station cabinets. Stable low contact resistance is maintained during whole equipment service life. The contact structure provides proper contact normal force, resisting continuous vibration caused by fan operation and outdoor mechanical shock. Compared with ordinary consumergrade connectors, this telecomoriented product strictly controls spring deflection and stress relaxation, avoiding signal dropoff or intermittent connection failures. Minimum 500 mating cycles ensure convenient module maintenance and replacement in field service scenarios.
• Antimisinsertion polarization & foolproof housing design The PPS plastic housing is molded with builtin polarizing key feature. It physically blocks reverse insertion or offset mating. Onsite maintenance technicians will not damage pin contacts by wrong insertion. This foolproof function greatly reduces humancaused hardware failure risk during base station installation and troubleshooting. The housing wall thickness is enhanced to improve mechanical strength. It is resistant to accidental bump and scratch during assembly and transportation. UL94V0 flame retardant PPS material suppresses fire spreading risk for powersignal mixed application inside telecom racks.
• Wide temperature adaptability for outdoor 5G infrastructure 5G base station equipment faces complex ambient condition: outdoor remote radio units may suffer low temperature in winter and high temperature when heat accumulates in cabinet in summer. This connector supports working temperature from 40℃ to +105℃. PPS housing keeps stable mechanical property under wide temperature swing. Contact spring will not lose elasticity under thermal cycling test. It can be used for both indoor BBU room and outdoor polemounted radio unit without extra protective modification.
• RoHScompliant leadfree manufacturing & easy PCB assembly All materials comply with RoHS 2.0 and REACH regulation, suitable for global telecomequipment export. Throughhole solder tail fits standard leadfree reflow soldering process. Soldertail tin plating brings good wettability. SMTrelated assembly work can be finished on standard production line without special tooling. The connector delivers consistent dimensional tolerance for highvolume automated assembly.
• Balanced powersignal mixeduse capability Each contact supports 3A rated current. It can transmit lowvoltage auxiliary power and control signal simultaneously. For many 5G submodules, designers need one connector to handle both power supply and status signal feedback. This 2×5P 2.8 mm pitch connector realizes mixed powersignal interconnection, reducing total connector quantity and simplifying whole harness architecture.
