Overview

In-depth Product Details & Applications

Solution Overview

The aerospace environment imposes the most extreme reliability requirements on connectors—vibration, shock, alternating high and low temperatures, vacuum, radiation, and other extreme conditions all pose severe challenges to connectors. This solution uses precision-machined round-hole pin headers/sockets, with a process level that exceeds the MIL-DTL-55302 standard, to provide the highest level of interconnection assurance for aerospace electronic equipment.

Main Application Areas

Flight control computers: Interconnection between flight control mainboards and sensor boards, servo control signals, redundant voting signals
Navigation systems: INS inertial navigation, GPS/GNSS receivers, air data computers, magnetic compasses
Satellite communication payloads: Transponder module connections, antenna control units, power amplifiers, RF distribution
UAV flight control: IMU inertial measurement units, GPS modules, motor drive control, data link radios
Ground test equipment: Flight data collectors, avionics integrated test benches, simulation equipment

Solution Advantages

Precision machining from high-quality beryllium copper/brass, with pin body straightness ≤0.05mm/inch; multi-layer plating process (nickel base layer + silver intermediate layer + gold/palladium surface layer) for extreme corrosion resistance; high-temperature PEEK/PPS materials used for insulators, with temperature resistance above 260°C; produced and inspected in accordance with GJB 2446/MIL-DTL-55302 standards.
